因民铁铜矿区地质演化复杂，构造样式具有多样性。在前人研究的基础上，利用钻孔与巷道编录资料制作东西向剖面地质图，结合矿区平面地质图对落因褶皱-断裂带进行分析，并推测落因复式倒转褶皱东翼几何形态。同时，对因民铁铜矿区深部三个巷道工程进行断裂要素测量，制作玫瑰花图进行分析。研究表明因民铁铜矿区深部断裂呈反扇形分布的几何学特征，与落因复式倒转褶皱具有构造和谐性趋势。通过对落因褶皱-断裂带特征与控矿规律的研究，发现落雪组中东川型铜矿体与因民组中稀矿山型铁铜矿体严格受落因褶皱-断裂带控制，认为在落因褶皱-断裂带东翼具有寻找隐伏稀矿山型铁铜矿床和东川型铜矿床的潜力。

The Yinmin iron-copper deposit with complex geological structure patterns experienced multi-stage geological evolution. In order to study the geometry of the Luoyin fault-fold belt, an east-west direction geological profile is mapped based on underground tunnel observation, and drilling hole-logging, of three levels from 2472 m, 2350 m, and 2230 m levels in the Yinmin iron-copper mine. In addition, the geological evolution of structure deformation is reconstructed based on structural analysis, of the Luoyin overturned compound fault-fold belt. To delineate the ore-controlling mechanism of the deposit, a rose-diagram of the fault-fracture was depicted based on the data from the above mentioned tunnels at the three levels. This study showed that fault-fractures at the depth of the Yinmin iron-copper deposit are in anti-fan-shape and are structurally concordant with morphological characteristics of the Luoyin overturned compound fold. In conclusion, the orebodies of the Dongchuan-type copper deposit and Xikuangshan-type iron-copper deposit were strictly controlled by the Luoyin fault-fold belt. Therefore, it may be predicated that the depth of the east limb of the Luoyin fault-fold belt might be plausible for exploration of the Dongchuan-type copper deposit and Xikuangshan-type iron-copper deposit.
