NEW PROGRESS IN THE STUDY OF THE ZETANG OPHIOLITIC MELANGE IN TIBET

摘要: 泽当蛇绿混杂宕是雅鲁藏布江蛇绿岩带重要组成部分，受控于板块结合带。它与国内、外某些典型的层序性蛇绿岩能够对比，形成于板内拉张裂谷，属边缘海或小洋盆的产物，时代跨越三叠纪－早白垩世。

Abstract: The Zetang ophiolitic melange is an important component part of the Yarlung Zangboophiolite belt and controlled by the plate junction zone. It may be well correlated with sometypical sequential ophiolites at home and abroad.The melange originated in an intraplate ex-tensional rift and is the product of the marginal sea or small oceanic basin. Its age ranges fromthe Triassic to Early Cretaceous.
