【摘要】 近二十年来国内外地球物理学家对利用航磁数据计算居里点深度感到兴趣。已发表了日本、美国及我国的部分地位的居里点等温面图,其結果某些与Pn波速的区域性变化相一致,某些指出居里等温面的空间变化与地热能面的集中密切相关,它们也可用于地壳结构的研究。本文介绍用航磁数据计算居里点深度的原理及方法并给出计算方框图。更多还原

【Abstract】 National and foreign geophysicts have been interested in calculating Curie Point depth by aeromagnetic data for about two. decades. Curie Point isother mal surface maps of Japan and of some regions in America and in China have been published. Some of the results are in agreement with regional variation in Pn velocity and some of them indicate a strong correlation between the spatial variation of the Curie isotherm level and the concentration of surface geothermal energy. They can also be used for the crust structure study. In this paper, the priciple and methods of the Curie Point depth calculation by aeromagnetic data are introduced and block diagrams of computation are given.更多还原
