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

将对支持简单热边界层模型的Heat.flow/基底深度关系进行测试，以确定它是否确实适用于较老的海洋地区。为了证明这一点，将使用在拟议的R/V Gyre巡航期间获得的热流测量和分析DSDP 90和91站点的放射性来记录墨西哥湾西部晚侏罗世洋底的热流，以确定来自10公里沉积物的辐射热源对表面热通量的影响。地震折射和反射数据将被用来计算含水的基底，以及比正常地壳更薄的可能对该深度的影响。

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.
