随着矿产普查、勘探工作的进展,对本区岩浆岩的研究亦渐趋深入。在1∶20万区域地质调查开展以前,甘肃省地质局、西北冶金地质勘探公司等所属队对岩浆型铁、铬有关的基性、超基性岩体以及与接触交代型铁矿有关的中酸性侵入体做过一些工作。1∶20万区域地质调查工作开展以后,对本区岩浆岩的空间分布、岩体类型、相互关系等做了研究,积累了较多的资料,为进一步研究、总结本区岩浆活动以及与成矿的关系奠定了基础。关于本区岩浆活动的时代,以往多属推论。近几年来,西北一八二队,甘
With the progress of mineral prospecting and exploration, the research on magmatic rocks in this area has also been deepening. Prior to the 1: 200,000 regional geological survey, the Gansu Provincial Geological Bureau, the Northwest Metallurgical Geological Exploration Company, and other subordinate teams of the magma-type iron and chromium-related basic and ultrabasic rocks and the associated metacrite-related iron ore Acid intrusion has done some work. After the work of 1: 200,000 regional geological survey, the spatial distribution of rock magmatism, the type of rock mass and their relationship have been studied and more data have been accumulated. In order to further study and summarize the magmatism in this area and the relationship with mineralization The relationship laid the foundation. The era of magmatic activity in the area, in the past mostly deduced. In recent years, the Northwest 182 team, Gan
