Introduction This report comprises the AFTA (apatite fission track analysis) data obtained for 27 samples from six wells supplied by the Alaska Geologic Materials Center (GMC) from the North Slope of Alaska. As part of the agreement between Geotrack International (Kerry Hegarty) and the Alaska GMC (John Reeder), Geotrack was obliged to supply the raw fission track data for the samples supplied. These data are supplied herein. The .data consists of: fission track ages (both individual grains and mean age), confined length measurements and the chlorine content of each age grain. No interpretations of the data are supplied herein. Geotrack appreciates the opportunity to have collaborated with the Alaska GMC. 2. Report structure Sample details are discussed in Appendix A, together with the yields of detrital apatite obtained after mineral separation. Sample preparation and analytical details are described in Appendix B, and are followed by presentation of al] AFTA data, including raw track counts and fission track ages for individual grains. The presentation of data in the form of Tables and Figures throughout the report is discussed in detail in Appendix B. 3. Data quality The quality of the AFTA data is considered to be excellent. Apatite yields in 18 of the 27 samples were excellent, with the remaining ranging from very poor to good. ~~lC DATA REPORT 3 3 3 Page 4/61 A.1 GMC Data Report 333 Page 5/61 APPENDIX A Sample Details A.1 Apatite yields and quality Twenty seven samples from six wells from the North Slope Region, Alaska were obtained for Apatite Fission Track Analysis (AFTA®) from the Alaska GMC. The yields of detrital apatite obtained after mineral separation varied from very poor to excellent with the majority being of excellent quantity, as summarised in Table A.1. The quality of the resulting AFTA data varied from very poor in two samples to excellent in most of the samples. Overall, the samples provided age and length data of excellent quality.

Cuttings samples are washed and dried before grinding to sand grade. The ground material is then washed to remove dust, dried and processed by conventional heavy liquid and magnetic separation techniques to recover heavy minerals. Apatite grains are mounted in epoxy resin on glass slides, polished and etched for 20 sec in SM HN03 at 20°C to reveal the fossil fission tracks. After etching, all mounts are cut down to 1.5 X 1 cm, and cleaned in detergent, alcohol and distilled water. The mounts are then sealed in intimate contact with low-uranium muscovite detectors within heat shrink plastic film. Each batch of mounts is .stacked between two pieces of uranium standard glass which has been prepared in similar fashion. The stack is then inserted into an aluminium can for irradiation. After irradiation, the mica detectors are removed from the grain mounts and standard glasses and etched in hydrofluoric acid to reveal the fission tracks produced by induced fission of 235U in the apatite and standard glass. B.2 Experimental Details Fission track ages Fission track ages are calculated using the standard fission track age equation using the zeta calibration method (equation 5 of Hurford and Green, 1983), viz: F.T. AGE _ ~ In ~ 1 + ~ ~ ~D Pl g PD .~ ~ B.1 D where: ~D = total decay constant of 238U (= 1.55125 x 10-10) ~ = Zeta calibration factor ps = Spontaneous track density pi = Induced track density pD = Track density from uranium standard glass g = A geometry factor (= 0.5) B.2 GMC DATA REPORT 3 3 3 Page 9/61 Fission track ages are determined by the external detector method or EDM (Gleadow, 1981). The EDM has the advantage of allowing fission track ages to be determined on single grains. In apatite, tracks are counted in 20 grains from each mount wherever possible. In those samples where the desired number is not present, all available grains are counted, the actual number depending on the availability of suitably etched and oriented grains. Only grains oriented with surfaces parallel to the crystallographic c- axis are analysed. Such grains can be identified on the basis of the etching characteristics, as well as from morphological evidence in euhedral grains. The grain mount is scanned sequentially, and the first 20 suitably oriented grains identified are analysed. Tracks are counted within an eyepiece graticule divided into 100 grid squares. In each grain, the number of spontaneous tracks, NS, within a certain number of grid squares, Na, is recorded. The number of induced tracks, N;, in the corresponding location within the mica external detector is then counted. Spontaneous and induced track densities, ps and pi, respectively, are calculated by dividing the track counts by the total area counted, given by the product of Na and the area or each grid square (determined by calibration against a ruled stage graticule or diffraction grating). Fission track ages may be calculated by substituting track counts, NS and Nl, for track densities ps and pi in equation B.1, since the areas cancel in the ratio. Translation between apatite grains in the grain mount and external detector locations corresponding to each grain is carried out using AutoscanTM microcomputer-controlled automatic stages (Smith. and Leigh Jones, 1985). This system allows repeated movement between grain and detector, and all grain. locations are stored for later reference if required. Neutron irradiations are carried out in a well thermalised flux (X-7 facility; Cd ratio for Au ~98) in the Australian Atomic Energy Commission's HIFAR research reactor. Total neutron fluence is monitored by counting tracks in mica external detectors attached to two pieces of NBS standard glass SRM612 included in the irradiation canister at each end of the sample stack. In determining track densities in external detectors irradiated adjacent to uranium standard glasses, 25 fields are normally counted in each detector, and the total track count ND is divided by the total area counted to obtain the track density pD. The positions of the counted fields are arranged in a 5 X 5 grid covering the whole area of the detector. For typical track densities of between ~5 X l Os and 5 X 106 this is a convenient arrangement to sample across the detector while gathering sufficient counts to achieve a precision of -~2% in a reasonable time. B.3 GMC DATA REPORT 3.3 3 Page 10/61 A small flux gradient is often present in the irradiation facility over the length of the sample package (note that this developed only in late 1991, after extended refurbishment of the reactor, before which no detectable flux gradient was present). If a detectable gradient is present, the track count in the external detector adjacent to each standard glass is converted to a track density pD and a value for each mount in the stack is calculated by linear interpolation. When no detectable gradient is present, the track counts in the two external detectors are pooled to give a single value of pD which is used to calculate fission track ages for each sample. A Zeta calibration factor, ~, has been determined empirically for each observer by analysing a set of carefully chosen age standards with independently known K-Ar ages, following the methods outlined by Hurford and Green (1983) and Green (1985). All track counting is carried out using Zeiss~R~ Axioplan microscopes, with an overall linear magnification of 1068 x using dry objectives. For further details and background information on practical aspects of fission track age determination, see e.g. Fleischer, Price and Walker (1975), Naeser (1979) and Hurford (1986). Track length measurements For track length studies in apatite, the full lengths of 'confined' fission tracks are measured. Confined tracks are those which do not intersect the polished surface but have been etched from other tracks or fractures, so that the whole length of the track is etched. Confined track lengths are measured using a digitising tablet connected to a microcomputer, superimposed on the microscope field of view via a projection tube. With this system, calibrated against a stage graticule ruled in 2µm divisions, individual tracks can be measured to a precision of ± 0.2 µm. Tracks are measured only in prismatic grains, characterised by sharp polishing scratches with well etched tracks of narrow cone angle in all orientations, because of the anisotropy of annealing of fission tracks in apatite (as discussed by Green et al., 1986). .Tracks are also measured following the recommendations of Laslett et al.. (1982), the most important of which is that only horizontal tracks should be measured. One hundred tracks are measured whenever possible. In apatite samples with low track density, or in those samples in which only a small number of apatite grains are obtained, fewer confined tracks may be available, and in such cases, the whole mount is scanned to measure as many confined tracks as possible. WYVI~V B.4 GMT DATA REPORT 3.3 3 Page 11 / 61 Integrated frssion track age and length measurement Fission track age determination and length measurement are now made in a single pass of the grain mount, in an integrated approach. The location of each grain in which tracks are either counted or measured is recorded for future reference. Thus track length measurements can be tied to age determination in individual grains. As a routine procedure we do not measure the age of every grain in which lengths are determined, as this would be much too time consuming. Likewise we do not only measure ages in grain in which lengths are measured, as this would bias the age data against low track density grains. Nevertheless, the ability to determine the fission track age of certain grains from which length data originate can be a particularly useful aid to interpretation in some cases. Grain location data are not provided in this report, but are available on request. B.3 Data Presentation Fission track age data Data sheets summarising the apatite fission track age data, including full details of fission track age data for individual apatite grains in each sample, together with the primary counting results and statistical data, are given in the following pages. Individual grain fission track ages are calculated from the ratio of spontaneous to induced fission track counts for each grain using equation B.1, and errors in the single grain ages are calculated using Poissonian statistics, as explained in more detail by Galbraith (1981) and Green (1981). All errors are quoted as ~ l 6 throughout this report, unless otherwise stated. The variability of fission track ages between individual apatite grains within each sample can be assessed using achi-squared (x2) statistic (Galbraith, 1981), the results of which are summarised for each sample in the data sheets. If all the grains counted belong to a single age population, then the probability of obtaining the observed x2 value, for v degrees of freedom (where v =number of crystals -1), is listed in the data sheets as P(x2) or P(chi squared). A P(x2) value greater than 5% can be taken as evidence that all grains are consistent with a single population of fission track age. In this case, the best estimate of the fission track age of the sample is given by the "pooled age", calculated from the ratio of the total spontaneous and induced track counts in all grains analysed. Errors for the pooled age are calculated using the 'conventional' technique outlined by Green (1981), W ~-VI~V B.s GIVIC DATA REPORT 3 3 3 Page 12/61 based on the total number of tracks counted for each track density measurement (see also Galbraith, 1981). A P(x2) value of less than 5% denotes a significant spread of single grain ages, and suggests that real differences exist between the fission track ages of individual apatite grains. A significant spread in grain ages can result either from inheritance of detrital grains from mixed source areas (in sedimentary rocks), or from differential annealing in apatite grains of different composition, within a narrow range of temperature. Calculation of the pooled age inherently assumes that only a single population of ages is present, and is thus not appropriate to samples containing a significant spread of fission track ages. In such cases Galbraith has recently devised a means of estimating the modal age of a distribution of single grain fission track ages which is referred to as the "central age". Calculation of the central age assumes that all single grain ages belong to a Normal distribution of ages with a standard deviation, 6, known as the "age dispersion". An iterative algorithm (Galbraith and Laslett, 1993) is used to provide estimates of the central age with its associated error, and the age dispersion, which are all quoted in the data sheets. Note that this treatment replaces use of the "mean age" which has used been in the past for those samples in which P(x2)<5%. For samples in which P(x2)>5%, the central age and the pooled age should be equal, and the age dispersion should be less than ~10%. Table B.l summarises the fission track age data in apatite from each sample analysed. Construction of radial plots of single grain age data Single grain age data are best represented in the form of radial plot diagrams (Galbraith, 1988, 1990). As illustrated in Figure B.1, these plots display the variation of individual grain ages in a plot of y against x, where: y = (zj - zo) /a; x =1/aj B.2 and; zj = fission track age of grain j zo = a reference age 6j = error in age for grain j In this plot, all points on a straight line from the origin define a single value of fission track age, and at any point the value of x is a measure of the precision of each individual grain age. Therefore, precise individual grain ages fall to the right of the plot (small error, high x), which is useful, for example, in enabling precise, young grains to be identified. The age scale is shown radially around the perimeter of the plot (in Ma). If W ~-V/~V B.6 G-MC BATA REPORT 3 3 3 Page 13/61 all grains belong to a single age population, all data should scatter between y = +2 and y _ -2, equivalent to scatter within f26. Scatter outside these boundaries shows a significant spread of individual grain ages, as also reflected in the values of P(x2) and age dispersion. In detail, rather than using the fission track age for each grain as in equation B.2, we use: zj = N . aj = { 1 /Nsj+ 1 /Nij } B.3 i~ as we are interested in displaying the scatter within the data from each sample in comparison with that allowed by the Poissonian uncertainty in track counts, without the additional terms which are involved in determination of the fission track age (pD, ~, etc). Zero ages cannot be displayed in such a plot. This can be achieved using a modified plot, (Galbraith, 1990) with: Nsi+3/8 ~ _ 1 f 1 1 zj =arc sin rJsj + Nij + 3/4 6j - 2 Nsj + N;j f B.4 Note that the numerical terms in the equation for zj are standard terms, introduced for statistical reasons. Using this arc-sin transformation, zero ages plot on a diagonal line which slopes from upper left to lower right. Note that this line does not go through the origin. Figure B.2 illustrates this difference between conventional. and arc-sin radial plots, and also provides a simple guide to the structure of radial plots. Use of arc-sin radial plots is particularly useful in assessing the relative importance of zero ages. For instance, grains with NS = 0, Ni = 1 are compatible with ages up to 900 Ma (at the 95% confidence level), while grains with NS = 0, N; = 50 are only compatible with ages up to ~14 Ma. The two data would readily be distinguishable on the radial plot as the 0,50 datum would plot well to the right (high x) compared to the 0,1 datum. In this report the value of z corresponding to the fission track age of each sample is adopted as the reference value, zo. Note that the x axis of the radial plot is normally not labelled, as this would obscure the age scale around the plot. In general labelling is not considered necessary, as we are concerned only with relative variation within the data, rather than absolute values of precision. W ~-VI~V B.~ GMC DATA REPORT 3 3 3 Page 14/61 Radial plots of the single grain age data in apatite .from each sample analysed in this report are shown on the fission track age data summary sheets at the end of this Appendix. Track length data Distributions of confined track lengths in apatite from each sample aze shown as simple histograms on the fission track age data summary sheets at the end of this Appendix. For every track length measurement, the length is recorded to the nearest 0.1 µm, but the measurements have been grouped into 1µm intervals for construction of these histograms. Each distribution has been normalised to 100 tracks for each sample to facilitate comparison. A summary of the length distribution in each sample is presented in Table B.2, which also shows the mean track length in each sample and its associated error, the standazd deviation of each distribution and the number of tracks (N) measured in each sample. The angle which each confined track makes with the crystallographic c- axis is also routinely recorded, as is the width of each fracture within which tracks are revealed. These data aze not provided in this report, but can be supplied on request.. Breakdown of data into compositional groups In Table B.3, AFTA data are grouped into compositional intervals of 0.1 wt% Cl width. Parameters for each interval represent the data from all grains with Cl contents within each interval. Distributions of Cl contents in all apatites analysed from each sample (i.e. for both age and length determinations) are shown on the fission track age data summary sheets at the end of this Appendix. Plots of fission track age against Cl content for individual apatite grains Fission track ages of single apatite grains within individual samples are plotted against the Cl content of each grain on the fission track age data summary sheets at the end of this Appendix. These plots are useful in assessing the degree of annealing, as expressed by the fission track age data. For example, if grains with a range of Cl contents from zero to some upper limit all give similar fission track ages which are significantly less than the stratigraphic age, then grains with these compositions must have been totally annealed. Alternatively, if fission track age falls rapidly with decreasing Cl content, the sample displays a high degree of partial annealing. B.8 GMG DATA REPORT 3 3 3 Page 15/61 B.4 A note on terminology Note that throughout this report, the term "fission track age" is understood to denote the parameter calculated from the fission track age equation, using the observed spontaneous and induced track counts (either pooled for all grains or for individual grains). The resulting number (with units of Ma) should not be taken as possessing any significance in terms of events taking place at the time indicated by the measured fission track age, but should rather be regarded as a measure of the integrated thermal history of the sample, and should be interpreted in that light. Use of the term "apparent age" is not considered to be useful in this regard, as almost every fission track age should be regarded as an apparent age, in the classic sense, and repeated use becomes cumbersome.
