Relationships between chemico-mineralogical composition and color properties in selected natural and calcined Spanish kaolins
TL;DR: A total of 21 raw, washed and ground Spanish kaolins were studied in this article, and the CIELAB color parameters significantly correlated with compositional properties such as mineralogy, the chemical analysis of elements, the free oxide contents (Al 2 O 3, SiO 2, Fe 2 O 4 ) extracted with ammonium oxalate and with citrate-dithionite-carbonate, and trace elements.

Naturally Occurring Contamination in the Mancos Shale
TL;DR: The elevated concentrations suggest that naturally occurring contamination should be considered when evaluating groundwater cleanup levels and major ion chemical reactions are dominated by calcite dissolution following proton release from pyrite oxidation and subsequent exchange by calcium for sodium residing on clay mineral exchange sites.
