Lacustrine deposits have gained more attention recently due to containing valuable source rocks of oil, coal, and uranium. Lacustrine deposits generally provide productive mining conditions but can prove challenging when underground mines are attempted due to the poor shear strength of clays and silts as well as the amount of moisture often locked in the layers due to a low permeability ...
Sediment heavy meltwater streams running out of or off of a glacial body will slow in velocity once in contact with a body of water. This decrease in velocity causes the streams to be unable to carry sediment and the sediment falls out of the water column. Heavier sediments will fall out of the water column first as the water velocity decreases.
Similarly, non-reactive phosphorus in the sediment can be remineralized into the reactive form. [2] Sediments are generally richer in phosphorus than lake water, however, indicating that this nutrient may have a long residency time there before it is remineralized and re-introduced to the system.

Lacustrine plains are plains formed when lakes filled with sediments are drained. There are several reasons why drainage might occur, but in all cases the water in the lake is lost, leaving behind a level land of sediments. The resulting plain is an area of flat land which is often rich in fine-grained sediments.
It is the uppermost formation of the lacustrine and fluvio-glacial sediments of paleolake Humboldt, that existed at the edge of the Eastern Hills until the latest Pleistocene. The uppermost sediments of the Sabana Formation were deposited during the Last Glacial Maximum , a time when the first humans populated the Bogotá savanna.
In geography and geology, fluvial sediment processes or fluvial sediment transport are associated with rivers and streams and the deposits and landforms created by sediments. It can result in the formation of ripples and dunes , in fractal -shaped patterns of erosion, in complex patterns of natural river systems, and in the development of ...
Indus Molasse, a continental clastic rock sequence (with rare interbeds of marine saltwater sediments) comprising alluvial fan, braided stream and fluvio-lacustrine sediments derived mainly from the Ladakh batholith but also from the suture zone itself and the Tethys Himalaya. These molasses are post-collisional and thus Eocene to post-Eocene.
The Cerro Azul Formation (Spanish: Formación Cerro Azul), also described as Epecuén Formation, is a geological formation of Late Miocene (Tortonian, or Huayquerian in the SALMA classification) age in the Colorado Basin of the Buenos Aires and La Pampa Provinces in northeastern Argentina.
