摘要

The objectives of the research are to (1) determine whether age and source ofunconfined and confined ground waters are the same beneath the southern, central, and northern High Plains, (2) determine whether confined ground water is derived from vertical leakage or from lateral inflow from an outcropping recharge area before hydrologic divides are formed, (3) evaluate whether geomorphologic or climatic change during the Quaternary accounts for the isotopically distinct ground water in confined aquifers, and (4) consider the implications of variations in isotopic composition of ground water for Quaternary paleoclimatology of the continental interior.
