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 ...
Sketch showing the main glacio-lacustrine (or glacio-marine) deposits & depositional processes. Sediments deposited into lakes that have come from glaciers are called glaciolacustrine deposits. In some European geological traditions, the term limnoglacial is used. These lakes include ice margin lakes or other types formed from glacial erosion ...
Sediment deposition in Garfield County, Montana. A lacustrine plain or lake plain is a plain formed due to the past existence of a lake and its accompanying sediment accumulation. Lacustrine plains can be formed through one of three major mechanisms: glacial drainage, differential uplift, and inland lake creation and drainage.

A diagram of various depositional environments. In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record.
Lacustrine terrace – A step-like landform; Lava field, also known as lava plain – Large, mostly flat area of lava flows; Oceanic basin – Geologic basin under the sea; Oceanic plateau – Relatively flat submarine region that rises well above the level of the ambient seabed; Outwash fan – Type of sediment deposition by a melting glacier
Varves form in a variety of marine and lacustrine depositional environments from seasonal variation in clastic, biological, and chemical sedimentary processes. The classic varve archetype is a light / dark coloured couplet deposited in a lake basin. During summer months, light laminae (thin layers) composed of silica and calcium carbonate are ...
