Is shale clastic
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.
In contrast, shale is a type of clastic sedimentary rock which contains mud, flakes of clay minerals and a trace amount of other minerals. Structure. Mudstone has a layered structure while shale has a single layer. Composition. Furthermore, mudstone mainly contains mainly clay and mud while shale contains clay, mud, and some minerals. Conclusion
