Sedimentary rock Mineral information data and localiti

A rock resulting from the consolidation of loose sediment that has accumulated in layers eg a clastic rock such as conglomerate or tillite consisting of mechanically formed fragments of older rock transported from its source and deposited in water or from air or ice or a chemical rock such as rock salt or gypsum formed by precipitation from solution or an organic rock such as...

Occurrence Mineralogy of Sedimentary Rocks

Minerals found in sedimentary rocks can be divided into 2 classes Allogenic minerals - These are formed elsewhere and transported into the area of deposition Authigenic minerals - These are minerals that are formed at the site of deposition either by direct...
