甘肃一铬铁矿的矿床特征,对研究地槽区超基性岩体铬铁矿成矿作用的特点和成因,有一定的重要性。在综合研究以往资料的基础上,本文对这个铬矿床形成的某些规律及成因问题试作初步探讨。一、区域和超基性岩体地质概况本区位于北天山华力西褶皱带的东延部分,区域地层及构造线呈近东西走向。矿区
The characteristics of Gansu-1 chromite deposit are of great importance in studying the characteristics and genesis of the chromogenic mineralization of the ultrabasic rock mass in the terrain area. Based on the comprehensive study of the previous data, this paper attempts to make a tentative discussion on some rules and causes of the formation of this chromium deposit. I. Geological overview of regional and ultramafic rock mass The area is located in the eastern extension of the Variscan fold belt in the North Tianshan Mountains. The regional stratigraphy and tectonic line are near east-west. Mining area
