东秦岭松树沟蛇绿岩产出的构造环境及其组合层序的厘定

A Preliminary Study of Tectonic Environment and Sequence of Songshugou Ophiolite in Eastern Qinling Orogenic Belt

在研究东秦岭松树沟蛇绿岩形成的区域构造格架的基础上，利用平衡剖面的理论，重新厘定了该蛇绿岩组合层序。表明它是东秦岭碰撞缝合带内保存较完整、序列较连续的杂岩体，与世界上一些典型蛇绿岩套及现代洋壳－上地幔剖面可进行对比。

he tectonic environment of Songshugou ophiolite in Eastern Qinling orogenic belt is composed of the Northern Qinling structural zone, the ophiolitic melange zone and Liuling flysch deformational zone. According to balanced cross-sections, the re-established ophiolite sequence is more complete and successful, and almost in comperison with other typical ophiolite sections and modern oceanic orust-upper mantle Based on field geologic mapping.
