广西龙胜地区的蛇绿岩并非是构造侵位于元古界丹洲群中的异地洋壳碎片,而是早期岩浆侵位的基性超基性岩席在原地遭受变形分解作用的透镜体型产物。岩石地球化学分析表明,龙胜蛇绿岩既不同于洋壳型蛇绿岩,又有别于岛弧型蛇绿岩,龙胜也不存在所谓的洋壳型和岛弧型两种蛇绿岩共存的现象。龙胜蛇绿岩是一种非构造侵位的另一种类型的蛇绿岩。
The ophiolite in Longsheng area, Guangxi, is not the structure of the crust in the different parts of the Danzhou group in the Proterozoic. Instead, the early ultramafic mantle in the early magmatic emplacement undergoes deformation and decomposition in situ . Rock geochemical analysis shows that the Longsheng ophiolite is different from both the oceanic-type ophiolite and the island-arc type ophiolite. There are also neither ophiolite-type nor-arc-type ophiolite Coexistence phenomenon. Longsheng ophiolite is a non-structural emplacement of another type of ophiolite.
