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
The genesis of the diamond mantle source suggests that diamond is formed at the bottom of the lithosphere and the top of the asthenosphere. The kimberlite or pegmatite lamprophyre is only a carrier that brings out the metallogeny. The anomaly of gravity balance not only reflects the tectonic activity in the deep crust but also reflects its Therefore, we should pay special attention to the search of young diamond-bearing rock masses in the Yuanshui River Basin
