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 ...
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 ...
Glaciolacustrine plains form when the lakes in the continental ice sheets drain and leave the rocky debris within behind. The most recent ice age, the Wisconsin, was a drive for glacial lake formation and the glaciolacustrine plain formation that followed. [3] Glacial lakes are grouped into categories which represent the conditions in which ...
Generally the outwash deposits are finer further from the margin of the ice. [12] The deposits often have distinct layers due to the seasonal and episodic changes in stream flow. [8] Outwash streams often flow into proglacial lakes, where they leave glaciolacustrine deposits. These mainly consist of silt and clay, with laminations on the ...
As a glacier melts, large amounts of till are eroded and become a source of sediments for reworked glacial drift deposits. These include glaciofluvial deposits, such as outwash in sandurs, [19] and as glaciolacustrine and glaciomarine deposits, such as varves (annual layers) in any proglacial lakes which may form. [20]
An prospecting dog is a dog that has been specially trained to aid prospectors in finding mineral deposits near but not on the surface of the ground. Many mineral ores (especially sulfide ores) emit a specific aroma that a dog can be trained to detect.

[1] [6] [7] When the lake drained it exposed the sandy and gravelly glaciolacustrine deposits left by the glacier, along a broad plain just west of Schenectady, where the Mohawk emptied into the lake. [8] Dune and deltaic sands, containing lenses of silty sand, silt and clay, [9] compose the topsoil which now underlies the Albany Pine Bush. [10]
