Study Notes
Types of Sedimentary Rocks
- Three types: clastic, chemical, organic
Clastic Sedimentary Rock
- Most common sedimentary rock type
- Forms through lithification of clastic sediments
- Classified based on grain size
Comparison of Conglomerate and Breccia
- Both categorized as coarse-grained sedimentary rocks
- Conglomerate is made of rounded particles
- Breccia consists of angular particles
Chemical Sedimentary Rocks
- Form from precipitation of dissolved minerals in water
- Common example includes evaporite minerals
Evaporite Minerals
- Three common types: calcite, halite, gypsum
Organic Sedimentary Rocks
- Form from accumulation and lithification of the remains of living organisms
- Examples include coal and some types of limestone
