一、概况锡矿山南矿区域出露地层为泥盘、石炭系沉积变质岩系。岩体受新华夏系构造作用,褶皱和断裂极为发育。矿区有复式背斜和入字形断裂二种主要构造体系。矿床地质构造见图1。受构造控制,矿床产于复式背斜西南倾伏端与入字形构造之 First, an overview tin mine south area exposed strata mud plate, Carboniferous sedimentary metamorphic rocks. The rock body is affected by the structure of the Xinhuaxia system, with extremely developed folds and faults. The mining area has two main structural systems: compound anticlines and in-line fractures. Deposit geological structure shown in Figure 1. Controlled by tectonics, the ore deposit is produced at the southwesterly dip of the compound anticlines and an inflectional structure
