Is shale clastic organic or chemical
Regarding the REE behavior in environments and surface processes such as diagenesis and weathering, it is known that their concentrations in water are extremely low and that their potential for interaction with terrigenous sediments after they have been deposited is equally negligible (Taylor and McLennan 1985 Taylor S.R., McLennan S.M. 1985.The …Shale. Shale is a lithified mud — a sedimentary rock composed mostly of clay- and silt-sized grains. There are several ways to define shale. Some definitions are rather narrow. Glossary of Geology published by the American Geological Institute defines shale as a laminated, indurated rock with >67% clay-sized minerals 1.
