摘    要:依据中国大陆三维速度扰动图象,编制了中国大陆现代岩石圈和华北—扬子地台古岩石圈厚度图,并对含与不含金刚石的金伯利岩及钾镁煌斑岩中部分指示矿物和上地幔捕虏体地质特征进行分析,发现岩石圈底部某些地球物理特征与金刚石赋存部位有密切关系。在此基础上,从深部角度讨论了含金刚石的金伯利岩及钾镁煌斑岩时空分布特征,并作了预测研究。

关 键 词:中国大陆  岩石圈厚度  预测  金刚石原生矿

Abstract:The paleo-lithosphere thickness charts of North China, Yangtze platform and the charts of present lithosphere are prepared based on the 3-D velocity disturbance images in Chinese continent. Analysis of the geological properties of xenolith in the upper mantle and of the indicator minerals in pay kimberlites, non-pay kimberlites and lamproites shows that there exists a close relation between the geophysical properties of the bottom of lithosphere and diamond occurrences. The chrondogical-spatial distribution of pay kimberlites and lamproites is worked out and studies for prediction are made in light of the above discussion.
Keywords:Chinese continent  thickness of lithosphere  predicting  primary diamond deposit prediction
