| 摘 要： | 干龙塘构造混杂岩带，总体上南北向展布，北与风庆铜厂街蛇绿岩套相接，南与牛井山蛇绿岩带及双江粟义带相接。由三亚带组成，各地质体间均由规模不等的逆冲断层或韧性剪切带分割。绿片岩中发现较多蓝闪石高压变质矿物；干龙塘剖面角闪绿泥片岩中获330～348Ma的同位素年龄。该带可能代表了古特提斯洋缝合线的位置。

| Abstract: | The Ganlongtang tectonic melange zone is extended generally in SN direction, contact with the ophiolite suite in the north and with the Niujingshan ophiolite zone and the Shuangjiang - Suyi zone in the south, which are composed of 3 sub - zones. The geological bodies are separated by the thrust or ductile shear zone of different scale. glaucophanes have been discovered in the green schist. A lot of high pressure metamorphic mineral The isotopic age of amphibole chlorite schist in Ganlongtang section is 330 -348 Ma. Perhaps this zone is a representative of the Tethys suture. |
