| 摘 要： | 我国东、西两条地幔陡坡带明显地控制着岩金矿分布，特别是它们相互联结的秦岭段的幔坡域，更是岩金矿发育地区，东部地幔台坪隆起区金成矿作用强烈，在金成矿上，华南地区与华北地区可相互媲美，故在华南找岩金矿是极有前景的。中部地幔台坪区是我国微细浸染型金矿最主要的分布地区。幔坳与岩金矿分布的关系次之，以天山幔槽和敦化幔坳的岩金矿分布较多。幔隆本身与岩金矿分布的关系不密切，但其周边地区岩金矿却发育，如四川盆地幔隆和准噶尔幔脊周边的金矿分布多即是反映。

RELATIONSHIP BETWEEN MOHO SHAPE AND DISTRIBUTION OF ROCK GOLD DEPOSIT IN CHINA |
| |
| Abstract: | Two mantle sharp gradient belts of the east and the west control the distribution of rock gold deposit in China, especially,mantle slope area of Qinlin section combined by them each other is still developmental region of rock gold deposit.Gold metallization is very in.tensive in the east upwarpet district of mantle plate.South China can compare favourably with very hopelul in South China. The centre mantle plate district is very main distributional location of gold ore deposit of micrograined desseminated type.The relationship between mantle depression and rock gold deposit is secondary.Tianshan mantle trough and Dunhua mantle depression have distributed more rock gold deposits among mantle depressions.The mantle uplift for oneself and distribution of rock gold deposit are not closely related,but rock gold deposits are developmental round mantle uplift, for example,the distributions of many rock gold deposits have been reflected this con.dition round mantle uplift of Sichuan basin and Zhungaer. |
