| 摘 要： | 狮泉河、古昌、永珠等地区出露的超镁铁岩具有各种典型的蛇绿岩套特征,它们构成一个完整的带,中间的不连续地区为白呈系所覆盖。该蛇绿岩带是班公-怒江蛇绿岩带的李生分支,是西藏板块内部在中生代中期张开又封闭的残留构造。

| Abstract: | The ultramafites close to Shiquanhe was discovered long ago. But those ultramafites have never been considered asophiolles connected with Bangong-Nujiang ophiolite belt. The writer demonatrates that, the Shiquanhe-Guchang ophiolite belt parallel to Bangong-Nujiang belt converges withthe later at Suoxian of Xizang. So, the Bangong-Nujiang belt is a complex suture zone. This complex suture zone was opened at early Mosozoic and was clossed at the end of Jurassic. Heace, it is a new suture inthe interior of lithosphere of Qinzhang plateau continent mass, insted of a collsion belt between Eurasian and Indian continent?. |
