CCZO -- Soil Mineralogy, Soil Geochemistry, Photographic Imagery -- Calhoun 70-m deep well -- (2019-2019)

Mineralogical and chemical data from the weathered portion of the 70m deep well located in the CCZO. Seven samples ranging from the surface to a depth of approximately 13 meters are the subject of varied analytics. This data set includes results from thin section petrography, X-ray powder diffraction (UGA Bruker D8 Advance, Co-radiation), energy dispersive spectroscopy (UGA JOEL Superprobe), and bulk sample elemental analysis (Actlabs: Canada, FUS-ICP and GRAV methods).

Data

Thin sections photos (representative) 7 samples (0 to 13.7 m) using 5X, 10x, 20X and 50x objective magnifications (photos are paired in plane polarized and cross polarized light). Summary of observations for thin sections.

X-ray diffraction patterns of size fractions of the 7 samples (0 to 13.7 m) in waterfall display. Comments and annotations are made on each figure to note mineralogical trends. Quantitative analysis of size fractions using Rietveld refinement method. Include mineral tau plots (after Brimhall et al, 1988), assuming quartz is conservative.

Bulk elemental data for 7 samples (0 to 13.7 m). Includes plot of chemical alteration index (CAI).

Elemental data for micas/hydrous phyllosilicates/clay minerals in 7 samples (0 to 13.7 m) from energy dispersive spectroscopy with selected backscatter electron images. Plots of selected paired element concentrations are includes with annotations to the figures.

本数据集源自位于CCZO地区深度为70米的井孔风化部分，涵盖了从地表至约13米深度的七个样本，并对其进行了多样化的分析。数据集内包含薄片岩相学分析结果、X射线粉末衍射（使用UGA Bruker D8 Advance，共辐射）、能量色散光谱（UGA JOEL Superprobe）以及批量样品元素分析（Actlabs：加拿大，FUS-ICP和GRAV方法）的数据。

数据包括：
- 使用5X、10x、20X和50x物镜放大倍数拍摄的7个样本（0至13.7米）的薄片照片（代表性照片），照片在平面偏光和交叉偏光下配对。
- 7个样本（0至13.7米）的X射线衍射图谱，以瀑布式显示，并在每张图上添加注释以记录矿物学趋势。使用Rietveld精修法对粒径进行定量分析，包括矿物τ图（根据Brimhall等，1988年的方法），假设石英为保守元素。
- 7个样本（0至13.7米）的批量元素数据，包括化学变化指数（CAI）的图表。
- 能量色散光谱测得的7个样本（0至13.7米）中的云母/水合层状硅酸盐/粘土矿物的元素数据，包括所选背散射电子图像。图表中包含所选成对元素浓度的绘图，并对图表进行了注释。
