海底热流的2D值模拟,以及简单地下盐体几何 形态系统变化的水底重力响应的2D数值模拟,指出了这两类数据在提取盐体几何形态信息方面的有效性。对一个特定的盐体几何形态而言,当盐体顶部深度增加时,通过上覆沉积层的热扩散引起了热流异常振幅的急剧下降。当盐体顶部深度大约为1千米时,热流响应对盐体通道岩的长度及盐舌片的厚度不敏感。除了大量对向着及穿过盐体热折射形式的热流异
2D numerical simulation of the seafloor heat flow and the 2D numerical simulation of the underwater gravity response simply by changing the geometry of the subsalt body are carried out. The validity of these two kinds of data in extracting salt geometry information is pointed out. For a particular salt geometry, the thermal diffusivity of the overlying sediments causes a sharp drop in the anomalous amplitude of the anomalous heat flux as the top depth of the salt increases. When the depth of the top of the salt body is about 1 km, the heat flow response is not sensitive to the length of the salt passage rock and the thickness of the salt flake. Except for a large amount of heat flow that is directed toward and through the salt refractory
