Sedimentary characteristics and rock forming processes

Sedimentary size

Fine, medium, coarse

Sedimentary shape

Rounded, sub rounded, angular

Sedimentary sorting

Well, moderately, poorly sorted

Short transport/depositional history

Coarse grains, angular, poorly sorted, eg. breccia

Long transport/depositional history

Fine grains, rounded, well sorted, eg. desert sandstone

Magnification equation

Magnification \= image size/actual size

Diagenesis

The physical and chemical changes occurring during the conversion of sediment to sedimentary rock

Lithification

The process that converts sediments into solid rock by compaction or cementation.
