Two Classifications of Sedimentary Rocks | Clastic/Detrital Sedimentary Rocks; Chemical And Biochemical Sedimentary Rocks |
First, sediments may originate as solid particles from weathered rocks, such as the igneous rocks. These particles are called detritus,and the sedimentary rocks they form are called | Detrital Sedimentary Rocks |
___________ are derived from material (ions) that is carried in solution to lakes and seas | Chemical and Biochemical Sedimentary Rocks |
processes by which sediments are transformed into solid sedimentary rocks | Lithification |
Two Processes of Lithification | Compaction; Cementation |
As sediments accumulate through time, the weight of overlying material compresses the deeper sediments. As the grains are pressed closer and closer, pore space is greatly reduced | Compaction |
