这是近20年板块构造理论问世以来,用最新的地质方法和见解所能获得的有利于能源和矿产资源的图件。地球动力学图提供了地球表层现今运动以及由于应力和密度不均匀将造成未来运动的资料。根据海洋卫星雷达测量海平面高度而获得的最新资料编制的重力等值线,它比以前任何图件更仔细地表示了大陆边缘,也精确地圈定了海槽和海山外缘的裸露的关节状隆起(高重力值反映的地形波长约为300公里)。特别是用最新的方法对石油钻井的井壁进行系统和定向的测量获得的岩石圈应力,反映在板块内部的最大水平挤应力方向似乎多与扩张轴向外的方向有关,与板块的绝对运动关系不大,历史时期断层位移反映地球表面现代的变形形式。火山活动和地震初动方向揭示了从地表到削减带底部的变形形式,表面的地层在消减带上被认为透入到很深的地幔。
This is a map of the energy and mineral resources that can be obtained with the latest geologic methods and insights since the advent of plate tectonics in the last two decades. The Earth Dynamics diagram provides information on the current movement of the earth’s surface and the future movement that will result from uneven stress and density. The gravity contour, based on the most up-to-date information obtained by sea-satellite radars on sea level measurements, shows the continental margin more carefully than any previous map and also precisely delineates the bare knuckles of the trough and seamounts Uplift (high gravity value reflects the terrain wavelength is about 300 km). In particular, the lithospheric stress obtained by systematically and directionally measuring the borehole wall of petroleum drilling by the latest method appears to be related to the direction of the maximum horizontal compressive stress inside the plate more in relation to the direction of the expansion axis and to the absolute movement of the plate Little relationship between the historical period of fault displacement reflects the Earth’s surface deformation of the modern form. Volcanic activity and the onset of the earthquake revealed a deformation pattern from the surface to the base of the abatement zone, where the surface formation is thought to penetrate into the deep mantle on the abatement zone.
