Sinan and illinoian upland tills, the aquifer consists essentially of the sankoty sand. Pennsylvanian and mississippian rocks underlie the pleistocene deposits and are not developed as a source of ground water where sand and gravel aquifers are present. Rocks below the mississippian contain water too highly mineralized for most domestic purposes.
Age sequence indicated by carets, which are on younger side of contact between deposits of different ages. 25 meter thick and are laterally con- tinuous for more than 5 meters.
Gravel deposit in the peoria region that he named the sankoty sand for its occurrence in the sankoty water-well field north of peoria (horberg 1950a). He believed the deposit to be “nebraskan” in age, which was the earliest glacial episode recognized at that time, and mapped its distribution along the ancient mississippi (horberg 1953).
(joseph augustine), 1881-1949: the pleistocene deposits of sankoty head, nantucket, and their fossils.
Pleistocene non-marine sediments are found primarily in fluvial deposits, lakebeds, slope and loess deposits as well as in the large amounts of material moved about by glaciers. Less common are cave deposits, travertines and volcanic deposits (lavas, ashes).
The mahomet bedrock valley is an east-west–trending buried valley in central illinois containing basal pleistocene sands and gravels making up the mahomet aquifer and the contemporaneous sankoty mahomet aquifer, which are the major sources of freshwater for east-central illinois.
To help establish the date of the deposits, they measured the same isotopes in rocky debris used in the earlier study. Another test used rare forms of oxygen, found within the sediment, which revealed that precipitation must have fallen at much lower elevations than the height of the current ice sheet.
To the east, where wisconsinan outwash terminates against wisconsinan and illinoian upland tills, the aquifer consists essentially of the sankoty sand. Pennsylvanian and mississippian rocks underlie the pleistocene deposits and are not developed as a source of ground water where sand and gravel aquifers are present.

A few of the glacial aquifers art major freshwater resources for numerous municipalities. This investigation focused on the mahomet aquifer (ma) and the sankoty mahornet aquifer, which are contemporaneous pleistocene-age unlithifled sands and gravels filling ancient bedrock valleys in east-central illinois.

It probably is present almost continuously in the deep part of the ancient mississippi valley throughout illinois, and it may extend to the gulf coast. The basal pleistocene sand, called the natchez formation, at natchez, mississippi, contains polished pink sand grains like those in the sankoty.
