| 摘 要： | 西昆仑地块是西昆仑造山带的重要组成部分，南北边界分别为康西瓦—苏巴什华力西期缝合带和库地—其曼于特加里东期缝合带。新疆普鲁一带下古生界地层，分布于西昆仑地块东部，主要由一套海相火山岩和浅海陆棚相细碎屑岩组成，并遭受了绿片岩相的变质作用。通过1：25万《于田一伯力克幅)区调工作，将新疆普鲁一带下古生界地层厘定为下古生界奥陶—志留系，认为形成的大地构造环境为大陆活动边缘。

| Abstract: | The western Kunlun mass is an important part of the western Kunlun orogenic zone. It is bound at the south and north sides by the Kangxiwa Subashi Hualixi suture zone and the Kudi Qimanyute Caledonian suture zone. The Lower Paleozoic strata in Pulu area of Sinkiang are distributed at the eastern part of the western Kunlun mass, which is mainly composed of marine volcanic rocks and sediments and metamorphosed by greenschist facies. The result of geological mapping of the Yutian Bolike quadrangle scale (1:250,000) has put the Lower Paleozoic strata at Pulu area into the Lower Paleozoic Ordovician and Silurian Systems. The tectonics should be in the continental marginal environment. |
