Shale mineralogy
Oil Shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid organic material. Liquid and gaseous hydrocarbons can be extracted from the oil shale, but the rock must be heated and/or treated with solvents.The contents of major oxides and the concentrations of trace elements were normalized to Post-Archean Australian Shale (PAAS) values. The Paleocene–Eocene carbonates are enriched in CaO, MgO, Cr, and Ni, whereas ...

In addition, depending upon the type of clay minerals present, shale may present shrink/swell problems (smectite and chlorite minerals), or squeeze/deformation problems (kaolinite and chlorite minerals). Siltstone Key Point. Silt does not have a precise composition.
