甘孜—理塘结合带中段蛇绿岩的地质特征

Geological Features of Ophiolite in the Middle Garzê-Litang Plate Junction

甘孜—理塘结合带中的蛇绿岩 ,从时间、空间分布及其岩石学、岩石化学、地球化学特征来看 ,可分为两部分。早期卡尔蛇绿岩组为大陆裂谷型蛇绿岩 ;晚期瓦能蛇绿岩组合为洋岛—洋中脊过渡型蛇绿岩。

Space-time Distribution, petrographic, petrochemical and geochemical characteristics of ophiolite in the middle Garzê-Litang plate junction indicate that the ophiolite may be divided into early continental rift ophiolite and late oceanic transitional (island-mid-oceanic ridge) ophiolite.
