笔者从六个方面厘定了丰山有色金属矿田拆离滑脱构造:地层厚度变薄甚至缺失;界面处构造岩发育;岩体顺层分布;界面处含矿热液作用异常发育;界面性质鉴定;断层组合特征。研究了丰山矿田拆离滑脱构造特征;初步探讨了其形成机制。从三个方面研究了丰山矿田控岩控矿规律:构造的拆离和构造剥蚀作用形成了最佳成矿组合序列;有利的容矿(岩)构造;多期矿化叠加。
The authors determine the detachment and detachment structure of Fengshan non-ferrous metal orefield from six aspects: the thickness of the strata is thin or even missing; the tectonic rocks are developed at the interface; the bedding is distributed along the strata; the mineralization is abnormally developed at the interface; Fault combination features. Studied detachment and detachment features of Fengshan Minefield and discussed its formation mechanism. From three aspects, we study the controlled ore-controlling regularity in Fengshan orefield: tectonic detachment and tectonic denudation formed the best metallogenic combination sequence; favorable ore-hosting (rock) structure; multi-stage mineralization superimposition.
