在充分收集、整理、综合研究中国大陆11条地学断面(简称GGT)、数十条其它地球物理剖面(地震剖面、大地热流、大地电磁测深等剖面)和覆盖中国大陆及邻区的剪切波三维速度结构资料的基础上,阐述了中国大陆及邻区地壳结构、岩石圈结构和软流圈结构,并对中国大陆矿产资源预测作了简单的讨论。中国岩石圈结构是在三种不同性质的软流圈基础上发展起来的,有明显的继承性。中国岩石圈结构在某种程度上与大地构造单元相吻合,说明地壳构造受到岩石圈的影响和制约。尤其在地震波垂向低速带上(地壳上地幔都表现为低速性质)是内生多金属矿带的良好产出环境。
To fully collect, collate and comprehensively study 11 geosciences sections (GGTs) in mainland China, dozens of other geophysical sections (such as seismic sections, geothermal heat, and magnetotelluric sounding profiles) and shear covering China and its neighboring areas On the basis of three-dimensional wave velocity structure data, the crustal structure, lithosphere structure and asthenosphere structure in the Chinese mainland and its adjacent areas are described. The prediction of mineral resources in mainland China is briefly discussed. China’s lithospheric structure is developed on the basis of three different types of asthenosphere, with obvious inheritance. The lithospheric structure of China is consistent with the tectonic units to a certain extent, indicating that the crustal structure is affected and restricted by the lithosphere. Especially in the vertical seismic velocity low-velocity zone (the crust and upper mantle are shown as low-speed properties) is a good environment for the production of endogenous polymetallic ore belt.
