By the early years of the twentieth century, as the geology of the continents began to be better known, it was realized that Permian and Precambrian glacial deposits
occur virtually on all continents and at low latitudes.
Each one is a semi-continuous belt of ground, ten to 300 ft higher than surrounding glacial deposits
, or perhaps just thicker till where it is plastered onto bedrock hills as in Logan County or northeastern Ohio.
For example, paleosols formed in glacial deposits
, such as the Sangamon paleosol in the United States and Canada (Hall 2000) and the Eemian soil in Europe (Stremme 1998), bave been important in identifying ancient surfaces and interpreting interglacial climates.
Various glacial deposits
exhibit a range of properties related to their potential use and limitations for geotechnical aspects.
The modern term for the search for mineral deposits using glacial deposits
is called 'drift prospecting.
A big freeze caused glacial deposits
found in the tropics, according to a computer model that simulated the planet's past climate.
They were up there at the top of the list of things to forget the instant you left school, along with how to make sodium nitrosulphate (or whatever) and the term for glacial deposits

His long-term study of glacial deposits
supports other contentions that thousands of years ago Earth experienced much wider average temperature swings than previously thought.
provide the sand for the dune building that continues now.
Alluvial mining refers to mining precious metal deposits (particularly gold and gemstones) found in alluvial deposits - which are deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits
Carbonate cementation in polar regions or within glacial deposits
in formerly glaciated areas have attracted interest as a potential indicator of hydrologic and permafrost conditions and palaeoclimatic proxies (e.
This size range is the terminal grade for calcite and dolomite and can be related to the provenance of the glacial deposits
The northernmost point of New Zealand's South Island is Farewell Spit, a sand bar jutting out into the Tasman Sea for 20 miles, the sand blown into huge drifts after being dumped there by currents loaded with glacial deposits
fed by the Southern Alps.
Gostin's team will explore other glacial deposits
that formed around the same time in other parts of the world to see if there is further evidence of the asteroid's impact on the microscopic creatures at that time.
were dealt with in more detail than in other regional reports, perhaps because better exposures made them more accessible to observation.
