Abstract

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.
