Sedimentology Journal
Sedimentology encompasses the study of contemporary sediments like sand, silt, and clay,and therefore the processes that end in their formation (erosion and weathering), transport, deposition and diagenesis.Sedimentologists apply their understanding of contemporary processes to interpret geological
history through observations of matter rocks and matter structures.
Sedimentary rocks cover to seventy fifth of the Earth's surface, record abundant of the Earth's history, and harbor the fossil record.
Sedimentology is closely coupled to stratigraphy, the study of the physical and temporal relationships between rock layers or strata.
The premise that the processes poignant the world nowadays area unit a similar as within the past is that the basis for determinant however matter options within the rock record were shaped. By scrutiny similar options nowadays to options within the rock record—for example, by scrutiny fashionable sand dunes to dunes preserved in ancient aeolian sandstones—geologists reconstruct past environments. There area unit four primary sorts of matter rocks: clastics, carbonates, evaporites, and chemical.Clastic rocks area unit composed of particles derived from the weathering and erosion of precursor rocks and consist primarily of fractional material. Clastic rocks area unit classified per their predominant grain size and their composition. within the past, the term "Clastic matter Rocks" were accustomed describe silica-rich clastic matter rocks, but there are cases of clastic carbonate rocks. The additional acceptable term is siliciclastic matter rocks.Organic matter rocks area unit necessary deposits shaped from the buildup of biological detritus, and type coal and shale deposits, and area unit generally found among basins of clastic matter rocks
