Investigations of the Thermal Evolution of Sedimentary Basins Using sup 40 Ar/ sup 39 Ar Thermochronology: Applications to Petroleum Exploration. Progress Report, April 1, 1985-March 31, 1986

摘要

As we approach half way through our current reporting period, we find our program of assessing the utility of microcline thermochronology (MTC) in elucidating sedimentary basin thermal histories progressing satisfactorily on the two proposed fronts - development of microanalysis and assessment of the application of MTC to the thermally complex Anadarko Basin. Several hardware setbacks prevented us from initial testing of the microanalytical system until mid-1985, and software development continued to years but by January 1986 the mass spectrometer and extraction system were mated and testing begun. A suite of samples have been collected from the Anadarko project and mineral separations completed. Sample analysis will begin following irradiation protocol. We anticipate achieving our contracted goals by the end of our reporting period. 1 fig., 1 tab. (ERA citation 11:019061)
