摘要
1∶5万理塘县、濯桑幅区调中首次在甘改—理塘结合带中段蛇绿岩中发现具有韧塑性变形变质产物的石榴硅镁石角闪片岩。该岩石的存在肯定了甘孜—理塘带的洋壳属性的同时 ,亦表明结合带中存在中温高压变质相系 。
Garnet-humite-hornblende schist is discovered in ophiolite suite in the Garzê-Litang suture zone by 1:50,000 regional geological survey in the Litang and Cogsum quadrangles. The schist is characterized by plastic deformation and metamorphism.This discovery gives a new evidence for oceanic crustal property of the Garzê-Litang suture zone.
