| 摘 要： | 阿尔金山走滑断裂带位于青藏高原北缘，向东北与北山构造带相带，它斜切了塔里木板块和柴达木地块，东天山构造带和祁连构造带，新近在该构造带中段苏呈什杰一带发现了高压－超高压岩石新类型－含菱镁矿石二辉橄榄岩，其与高压壳源型榴辉岩共生一起，为幔源型超高变压岩构造侵位的产物。

| Abstract: | The strike-slip flauted zone of Altgn Tagh is located in the northern margin of Qinhai-Tibet plateau, and to northeast it links with Beishan mountain , and bevels Talim plate , Qaidam massif as well as structural zone of eastern Tianshan mountain and Qilian mountain respectively . A new type of high-ultrahigh pressure belt, garnet-lherzolite , is recently discovered in Sushijie where it is middle section of the strike-slip faulted zone. It coexists with high pressure eclogite of crustal source type. The authors consider that it is the product of tectonic emplacement of mantel source type. |
