如所周知,攀枝花——西昌地区(以下简称攀西)分布着一群具韵律旋回的层状火成岩体,并盛产举世闻名的攀枝花式钒钛磁铁矿床,历来引起广大地质工作者的极大兴趣。关于这类岩体生成的构造条件,过去一般泛指受区内某一深(大)断裂系的控制,对其控岩控矿的断裂构造形式和力学性质也很少加以讨论。有关这类岩体的成岩成矿机理更是众说不一。去年以来,我们应用裂谷构造和火成堆积学说,经过对米易白马层状岩体的典型解剖,结合其它几个层状岩体的综合分析,认为攀西地区具韵律旋回的层状岩体群是在裂谷
As we all know, Panzhihua - Xichang area (hereinafter referred to as Panxi) distribution of a group of rhythmic layered igneous rock mass, and rich in the world-famous Panzhihua vanadium-titanium magnetite deposit has always been of great interest to the majority of geological workers. The tectonic conditions for the formation of this type of rock mass in the past generally refer to the control of a deep (large) fault system in the area and rarely discuss the fault tectonics and mechanical properties of the rock-controlled ore-control ore. The diagenesis and mineralization mechanism of this type of rock mass is even more different. Since last year, we have applied rift tectonics and volcanic accumulation theory. After the typical dissection of the Miyi Baima stratigraphic rock mass and the comprehensive analysis of several other stratiform rock mass bodies, The body mass is in the rift
