	Geology of Baxter State Park - Glacial Geology - Deposition - Maine Geological Survey
		All types of glacial deposits are called glacial drift, a term handed down from the 18th and early 19th centuries, when glacial deposits were considered to be the result of icebergs drifting in the Biblical flood.
		There are two types of drift deposits: unstratified drift, or material deposited directly by a glacier, and stratified drift, or sediments washed from glaciers into meltwater streams and deposited as sand and gravel.
		Kettles or kettleholes are depressions formed in deposits of stratified drift, caused by the melting of a large block of ice which had been buried in the sand and gravel.

		In Christianity, the Deposition is the removal of Christ from the cross, at the Crucifixion.
		In Archaeology, deposition is physically similar to that of geology.
		In rapid prototyping, fused deposition modeling is a process by which a part is constructed by depositing material layer by layer.

	Deposition (geology) - Wikipedia, the free encyclopedia
		Deposition, also known as sedimentation, is the geological process whereby material is added to a landform.
		This is the process by which wind, water, or ice create a sediment deposit through the laying down of granular material that has been eroded and transported from another geographical location.
		Deposition can also refer to the build up of a sediment from organically derived matter or chemical processes.

	Deposition and Sedimentary Rock Formation
		This deposit stretched from north of Banff to south of Canmore.
		Since sedimentary rocks are the result of a sequential process of erosion and deposition, we can often find a mixture of many minerals trapped in their stony facade.
		Deposits that have not been recycled numerous times may also contain significant amounts of minerals like feldspar, mica, and olivine.

		The deposits closest to the land surface and the physiography, in general are the result of glacial advance and retreat during the last glacial period, the Wisconsin.
		The outwash deposit is composed of stratified and sorted sand and gravel that represents an aggradational deposit of a large discharge of meltwater and sediment at and beyond the ice sheet margin at that time.
		Because this upland deposit is composed of permeable sand and gravel, the outwash plain is a main ground-water recharge area and the deposits comprise a principal aquifer of the area.

		Percolating water from the hill the deposit occurs within is strongly radioactive and was sold in the 1920s for therapeutic purposes.
		The geology of the Silver Crater Mine site is similar to the geology of the Fission site, and the calcite vein-dike is part of the same group of calcite vein-dikes that dot the countryside near Bancroft.
		This process occurs when vein-dike, which was hydrothermally deposited or injected as a molten liquid, is reheated enough to cause the evenly distributed biotite, hornblende, betafite, apatite, and so forth, in the wall-rock in the calcite vein-dike to start to migrate and form larger crystals in the calcite vein-dike.

	An Introduction to Geology and Hard Rock Mining
		Geology is the study of the earth, its surface configurations, and the physical and chemical processes acting upon its surface and its interior.
		Deposits of coal, petroleum and naturally occurring brines do not fit such a rigorous definition, but have in generic terms also been considered minerals, principally because they are not readily identifiable as either animal or vegetable.
		Mineral deposits are not uniform either in their physical character of the wallrock (hardness, toughness, stand-up time, required support), or in the nature of the ore and gangue minerals (intergrowths, variations in composition, intensity of oxidation and/or alteration processes acting on the ore minerals influencing their metallurgical behavior).

		Geology is the study of the earth, its structure, composition, and history.
		Because such evidence of rapid deposition is so often found in the rocks of the earth, a revolution has been going on for a number of years in the estimates of the time it took to lay down strata.
		Even if the deposition of a group of strata is claimed to have taken millions of years, if the strata are penetrated by a polystrate tree fossil it is clear that the time was really less than it takes for a tree to rot out and fall down.

		Sensitivities to acid deposition, ranked high, medium, and low are assigned on the basis of bedrock compositions and their associated soils, and their capacities to neutralize acid precipitation.
		Fifty four percent of the approximately 37 million acres comprising the area of the SAA region is highly sensitive to acid deposition (having negligible or no capacity to neutralize), twenty percent as medium, and twenty six percent is rated as having low sensitivity.
		Bedrock geology and surficial geologic deposits have been shown to exert an important influence on the chemical composition of stream water and on the sensitivity of aquatic ecosystems to acid deposition (Norton and others, 1982).

	GEOLOGY OF BELIZE and Ambergris Caye, Belize
		The Quaternary (Pleistocene) rocks and modern sediments along the coast, and under water, are the youngest cycle of deposition in Belize, and are represented largely by shallow-water, limy sediments.
		Along its entire length the modern barrier reef sits atop a prominent fault that separates the shallow platform to the west from the deeper Caribbean to the east, where water depths progressively approach 4000 meters.
		The area was faulted about 1.8 million years ago as sea level fell, exposing the older shelf, and the consequence of that was the creation of a high ridge along the shelf edge that became the site of coral growth.

		Although of great age (deposited between 2,800 and 2,000 million years ago), the rocks are remarkably well preserved, and are of great economic importance.
		Huge thicknesses of glacial deposits - tillites, varved clays, and sandstones - were laid down; the Dykwa glacial sequence of the Karroo basin is 800-900 m/2,600-2,950 ft thick, suggesting a lengthy glaciation.
		The Permian glacial deposits were closely followed by the deposition of coal measures (of economic importance in the Wankie basin of Zimbabwe), followed in turn by shales, sandstones, and finally the Karroo basalts.

	Reading A Stream
		Perhaps the trickiest theories yet to confront the beginning gold-dredger are those that relate to placer geology, also known as "the science of stream deposition." Placer geology concerns the varying conditions which cause gold and other heavy materials to be deposited in a streamflow environment.
		Without a doubt, the best way to learn the ins and outs of gold deposition is to place yourself at the feet of a genuine "old-timer", but unfortunately not too many of us have access to such a person; we will therefore have to study the facts relating to placer geology from books.
		There are so many variables involved in the science of placer geology it would be virtually impossible to mention all of them, but basically, the deposition of heavy materials in a stream is based upon the speed and volume of water flow coupled with the shape and slope of the river channel.

		The deposition of these alternating sediment layers continued as several thousand feet of strata were deposited.
		During the latter part of the Triassic period the area was down-warped, and the seawaters came in and deposited the sediments of the Haro formation.
		The loose and unconsolidated sediments deposited during the different glacial invasions and interglacial intervals were left in such a position that in some cases they were exposed to the action of the waves.

		Both clastics and carbonates were deposited in a mixed marine and nonmarine environment, with clastics predominating in the eastern part of the State.
		Swamp conditions prevailed, resulting in the deposition of thousands of feet of nonmarine sandstone and shale and the many important coal seams that we know today.
		Important lake deposits, predominantly clay, were thus laid down in the Monongahela River basin.
