Water-Pressure Systems


pools of subterranean waters, which are distinguished with respect to all the principles of formation and propagation of subterranean waters. Water-pressure systems may pertain to one or several geological structures or to a part of one structure; they cover regions of present supply, drainage, and discharge. They may be represented by artesian basins of various sizes. Most ba-sins are assy metrical (like artesian slopes), with various dis-charge cells (open and closed). In many basins it is possible to establish the overflow of water from one system to another; all water-pressure systems of the earth’s crust are connected to each other. The depth of the base of water-pressure systems in platform areas is usually determined by the position of the old crystalline foundation. Depending on the rock complex that makes up the basin, there are one-, two-, or multilevel basins of subterranean waters.

In large, multilevel basins, the underground discharges for various levels may proceed in opposite directions. Water-pressure systems frequently include formations of fresh or mineral waters and brines. Analysis of the hydrogeochemical zonality of the basins with respect to both the gas and chemical composition of the waters and the content of rare and radioactive elements and organic substances makes it possible to draw important conclusions relating to prospecting for mineral resources.
