Clastic Sedimentary Rocks

Sedimentary rocks are divided into other groups They are clastic or non clastic This grouping tells more about how the rocks formed and what they formed from 2 Rocks that are made of bits of other rocks that have been weathered eroded and deposited are called clastic rocks Clasts are the fragments of rocks and minerals Examples of

Sedimentary Rocks and Processes

WEATHERING All rocks igneous metamorphic and sedimentary exposed at the Earth s surface are subjected to the relentless effects of weathering Physical weathering acts to break up rocks into smaller pieces while chemical weathering acts to change the composition of various minerals into other minerals or forms which are stable at the temperature and pressure conditions found at the Earth

Sedimentary Rock Classification How Do You tell One

Sedimentary rock is classified into two groups based on how they form They are clastic and chemical. Clastic sedimentary rock is formed as bits of weathered rock become cemented together Because all kinds of rock are subject to weathering many different minerals can make up this group of rocks.

Clastic Sedimentary Rock Classification

26 10 2000  Sedimentary rocks are classified on the basis of the texture grain size of the rock and composition The basic classification only concerned texture using the Wentworth size scale.But any full rock name must specify both texture and composition Thus an arkose sandstone is a rock of sand sized particles with a high percentage of those particles being feldspar.
