Clastic - Rocks that are formed from the fragments ( Clasts) of any other rocks. Chemical - There are two types of Chemical Sedimentary Rocks. Biogenic - Rocks that are formed from the activity of life forms ( biological ). Precipitate - Rocks that are formed from naturally precipitated minerals.There are a few categories of mudstone. These categories include siltstone, claystone, mudstone (mudstone can be further categorized into shale and argillite). What is Shale. Shale is a type of clastic sedimentary rock that contains mud, flakes of clay minerals and a trace amount of other minerals. More precisely, shale is a thin layer of mudstone.Mudstone. Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from shale by its lack of fissility (parallel layering). [1] [2] The term mudstone is also used to describe carbonate rocks ( limestone or dolomite) that are composed predominantly of carbonate mud. [3] Concretions are hard bodies that form in sediments before they become sedimentary rocks.
