What is the difference between siliciclastic and carbonate rocks and the common siliciclastic and carbonate rocks?

Answer 1

There are many differences between siliciclastifc and carbonate rocks as you can see below,

1- dominant sediment grian size range. In carbonate slopes is it mud to boulders but it is mud to sand in siliclastic sediments.

2- sand grain characteristic. The grains are irregular to spherical shapes in carbonate, primary intragranular and microporosity common and the grains in siliciclastic are ingular to spherical shapes, primary intragranular and microporosity uncommon.

3- The third difference is the mud characterstic since it is aragonite needles, planktonic skeletal forms and less cohesive when it is platy micaceous forms, and more cohsive in siliciclastic.

4- The dominate sediment sources are paltform top, margin, slope, and water column but they are hinterland and water cloumn in siliciclastic.

5- The early lithification also differ between those rocks. It is submarine cementation and biological binding and uncommon in siliciclastic.

6- The maximum slope declivities. The re-sedimented is 35-40° in the carbonate sediments when it is 3-6° in the silicicaltic.

7- Sediment dispersal. it it inherently line-fed, requries sediment focusing mechanism for downslope point source when in the silicicaltic it is inherently point-courced with modification from strike reworking.
