中文摘要:文章汇集了中国大陆人工地震、天然地震层析成像、大地电磁、地热等资料,给出了中国大陆及其邻近海域岩石圈速度结构。以南北带为界,中国大陆岩石圈划分为东、西两个基本单元。西部和东部的华南岩石圈厚;东部的东北、华北和邻近海域岩石圈薄。以南北带为界,中国大陆岩石圈地幔划分为东、西两个基本单元。西部和东部的华南为高速厚幔区;东部的东北、华北和邻近海域为低速薄幔区。

Relationship between Lithospheric Structures and Metallogenic Processes in Five Major Metallogenic Domains of Chinese Continent
Abstract:Based on geoscience transects and seismic data,the authors collected data from such aspects as seismic tomography, magnetotelluric survey and geothermal exploration, determined the thickness and constructed the velocity model of the crust in various metallogenic provinces of China. The crust gradually becomes thinner and thinner from east to west in China.The velocity-histogram map of the crustal structure was compiled in accord with the metallogenic provinces of China. The horizontal low velocity layer, the vertical low velocity zone and the high velocity layer in the basement of the lower crust are related to the ore-forming processes.
