Is shale clastic organic or chemical

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.

ADVERTISEMENT What Are Sedimentary Rocks? Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, conglomerate, sandstone, siltstone, and shale.However, the cause and extent of increased marine primary productivity during this time interval remain unknown. To estimate the primary productivity in a late Neoproterozoic sea, this study investigated the Sirbu Shale, Vindhyan Supergroup, for trace elements, organic carbon isotopes and total organic carbon (TOC).1. Introduction.
