北祁连山是我国典型的早古生代优地槽,对于它的发生、发展及其建造、改造特征的研究,不仅在探讨中国地壳的发育演化史上具有一定的理论意义,而且在普查找矿上也具有一定的实际意义。北祁连山的蛇绿岩,引起许多地质学者的注意。板块学说引进我国以来,先后有人将北祁连山的蛇绿岩作为洋壳碎片进行研究,并提出了它的时代及序列。笔者等对北祁连的构造发展史、海相火山岩的产出特征、岩浆岩发育顺序、超基性岩的高温热岩浆侵入及其接触变
North Qilian Mountain is a typical Early Paleozoic trough in China. The study on its occurrence, development and its characteristics of construction and alteration not only has certain theoretical significance in exploring the development and evolution of the crust in China, but also has a Certain practical significance. The ophiolite in the North Qilian Mountains has attracted the attention of many geologists. Since the introduction of plate theory in our country, some people have studied the ophiolite in the North Qilian Mountains as the fragments of the oceanic crust and put forward its era and sequence. The author of the North Qilian tectonic history, marine volcanic output characteristics, magmatic rock development sequence, ultramafic rock high temperature hot magmatic intrusion and its contact change
