GEOL 1401 Sedimentary Rocks
Sedimentary Rocks - Comes from preexisting rocks (from rocks sediments)
-
Detrital sediments: Particles derived by weathering
Chemical sediments: Minerals extracted from solutions (seawater) by : Inorganic processes Organic processes
(processes that break down rocks into smaller pieces)

Sedimentary Rocks Weathering takes place when some process breaks a parent material into smaller pieces.
-
Sedimentary Rocks - Three important processes takes place during the formation of sedimentary rocks:
-
1. Transportation 2. Deposition 3. Lithification
