Study Notes
Formation of Sedimentary Rocks
- Sedimentary rocks form through various processes, with lava cooling being an exception.
Definitions and Terminology
- Sediment Sorting: Refers to the range of particle sizes found within sediment.
- Layering: Also known as stratification, it describes the arrangement of sediments and rocks in distinct layers.
- Texture: Relates to the grain size of sedimentary materials.
- Grain Roundness: Indicates the loss of edges on sediment grains, which is a product of weathering and transport.
Clastic Rocks
- The formation of clastic rocks does not involve the build-up of plant materials, a process more relevant to organic rocks.
Chemical Rocks
- Chemical sedimentary rocks are formed from crystals that precipitate out of a solution.
Depositional Environments
- Sedimentary Depositional Environment: An area where sediments are deposited.
- Alluvial Fan: A continental deposit characterized by gravel and sand.
- Sand Dunes: Formed as sand mounds in desert regions.
- Beach Sand: Represents sediments deposited along shorelines.
- Reef: Structures built from calcareous skeletons of organisms, resistant to wave action.
Fossils
- Fossils are defined as remains or traces of organisms preserved in sedimentary rock.
Sedimentary Structures
- Not all geological formations are considered sedimentary structures; for instance, magma emplacement does not qualify.
Sediment Transport
- Stratification is a process related to sediment layering and does not serve as a transporting agent, unlike water or wind.
Coal Formation
- Coal originates in swamp environments, where organic materials accumulate and undergo metamorphism over time.
Clastic Rock Composition
- The composition of clastic rocks is influenced by the surrounding geological environment, excluding the type of vegetation present, such as the type of plant growing near a river.
