GEOG 150 Lecture Notes - Lecture 6: Silt, Cross-Bedding, Dolomite
Detrital sedimentary rock
Rocks tear form from the accumulation of materials that originate and are transported as solid particles
derived from both mechanical and chemical weathering.
Chemical sedimentary rock
Sedimentary rock consisting of material that was precipitated from water by either inorganic or organic
means.
Organic sedimentary rock
Sedimentary rock composed or organic carbon from the remains of plants that died and accumulated on
the floor of a swamp. Coal is an example.
Shale
The most common sedimentary rock, consisting of silt and clay sized particles.
Fissility
The property of splitting easily into thin layers along closely space, parallel surfaces, such as bedding
planes in shale.
Sorting
The degree of similarity in article size in sediment or sedimentary rock.
Conglomerate
A sedimentary rock composed of rounded, gravel sized particles.
Breccia
A sedimentary rock composed of angular fragments that were lithified.

Sedimentary rock consisting of material that was precipitated from water by either inorganic or organic means. Sedimentary rock composed or organic carbon from the remains of plants that died and accumulated on the floor of a swamp. The most common sedimentary rock, consisting of silt and clay sized particles. The property of splitting easily into thin layers along closely space, parallel surfaces, such as bedding planes in shale. The degree of similarity in article size in sediment or sedimentary rock. A sedimentary rock composed of rounded, gravel sized particles. A sedimentary rock composed of angular fragments that were lithified. A type of chemical sediment that forms when material dissolved in water is precipitated by water- dwelling organisms. Limestone can from by inorganic means or from biochemical processes.
