Silisiclastic Rocks Flashcards
Created by accumulation of existing rocks or fragments of extinct organisms on the Earth’s surface.
Sedimentary Rocks
Conglomerate, Breccia, Sandstone, Shale, and Shale/Musdtone are examples of ____________.
Clastic Rocks
Rocks formed by evaporation of saline water. Eg. Gypsum
Evaporate Rocks
Formed by chemical and organic sources (BIOCHEMICAL), these rocks form from CaCo3. Eg. Dolomite
Carbonate Rocks
Forms due to decomposition of organic remains under temperature and pressure. Eg. Coal
Organic Rocks
How are sedimentary rocks classified?
Their COMPOSITION and by the MANNER how they are formed.
Made from the broken fragments of other rocks, cemented by minerals.
Clastic Sedimentary Rocks
A clastic sedimentary rock formed by an angular gravel and boulder-sized clasts cemented together in a matrix. ANGULAR IN NATURE.
Breccia
A clastic sedimentary rock formed from the compaction of silt and clay-size mineral particles.
Shale
A clastic sedimentary rock where sand is laid and buried in beaches, dunes, and seafloors.
Sandstone
Weathering, Erosion, Deposition, Compacted, and Cemented are ____________.
The ways of how a Sedimentary Rock form.
A process where sedimentary rocks are altered after they are deposited, but before they are buried and lithified.
Diagenisis
A classification of sedimentary rocks where it is made from rounded pebbles and cobbles. Eg. Conglomerate and Breccia
Crudaceous Rocks
A classification of sedimentary rocks where it is made up of mainly sands. Can be accumulated by wind or deposited underwater. Eg. Sandstone
Arenaceous Rocks
A classification of sedimentary rocks where it is made up of clay sized sediments. Eg. Shale
Argillaceous Rocks
