The six ore samples are quartz sandstones in which rounded quartz grains and minor feldspar, lithic clasts, heavy detrital minerals, and coalified plant material are the detrital constituents. Consistent with this lithology, whole-rock geochemical results from sandstone ores of the same deposit contain from 57 % to 81 % SiO 2 (Bos-Orent, 2021).

Sandstone mineralogy has been quantified by point counting, and mudrock mineralogy semi-quantified by XRD. The detrital and authigenic mineralogy in the sandstone is almost identical to that found in the mudrock. The principal difference is in the relative proportions.
