| 摘 要： | 金刚石幔源成因论认为金刚石在岩石圈底部、软流圈顶部生成,金伯利岩或钾镁煌斑岩仅为载体将其带出成矿,重力均衡异常既反映地壳深处构造活动,又反映其活动的近期性,为此,要特别注意沅水流域年轻的含金刚石岩体的查找

| Abstract: | The mantle derivation theorists of diamonds hold that diamonds are formed at the bottom of the lithosphere and the top of the rheosphere,and the kimberlites or lamproites only serve as carriers for bringing diamonds out to form deposits.The gravity isostatic anomalies reflect not oly the tectonic activities at the depth of the earth crust but also the short term character of these activities.Hence special importance should be attached to the prospecting for young diamond bearing rock bodies in Yuanjiang river area. |

| Keywords: | gravity isostatic anomaly mantle uplift fracturing diamond |
