Heat Flow/Basement Depth Relation for the Ocean Crust in theEastern Gulf of Mexico: A Constraint on Thermal Models of the Ocean Lithosphere?

支持简单热边界层模型的热流/基底深度关系将被测试，以确定它是否真的适用于更古老的海洋地区。为了证明这一点，将在墨西哥湾西部晚侏罗世海底记录热流，使用在拟议的R/V环流巡航期间获得的热流测量数据，并分析DSDP 90和91站点的放射性，以确定来自10公里沉积物的放射性生热对地表热通量的影响。地震折射和反射数据将用于计算含水基底和薄于正常地壳对该深度的可能影响。

The heat-flow/basement depth relation, which favors the simple thermal boundary layer model, will be tested to determine if it actually is applicable to older oceanic areas. To document this, heat flow will be documented in the Late Jurassic ocean floor of western Gulf of Mexico using both heat-flow measurements acquired during a proposed R/V Gyre cruise and also analyzing the radioactivity of DSDP 90 and 91 sites to determine the effect of radiogenic heat from 10 km of sediments on the surface heat flux. Seismic refraction and reflection data will be used to compute the water-loaded basement and the possible effect of thinner-than- normal crust on this depth.
