摘要:
通过对太行山南段平顺铁矿矿区构造特征及岩浆岩的动力学分析研究,认为第一岩浆岩带属于被动侵位机制,岩体内部成矿潜力较大;第二岩浆岩带为主动侵位机制,背斜核部及岩体与围岩的接触部位为有利成矿区。同时根据岩石、矿石的稀土元素、微量元素、Pb同位素特征及矿体与岩体的关系,认为晚期闪长岩是主要的成矿母岩,但早期基性—超基性岩间接为铁矿的形成提供了一定的物质来源;矿体的形态明显受到接触面及周边构造形态的控制,呈不规则板状、透镜状、分枝状、羽状分布。最后运用矿体成矿规律、磁异常、电法异常等找矿预测方法,在研究区内圈出了龙降沟岩体南缘、双井、东郊3个找矿预测区。
Abstract:
Tentonic characteristics of iron deposit in Pingshun Area of Southern Taihang Mountain and kinetics characteristics of magmatic rocks were discussed. The first magmatic belt belongs to passive emplacement mechanism, forming ore bodies potentially; the second belt belongs to initiative emplacement mechanics, forming ore bodies potentially in anticlinal nucleus and the contact zone of rock and wall. According to the characteristic of rare earth element, trace element and Pb isotope in rock and ore and the relationship between ore and rock bodies, the later diorite is main metallogenic mother rock, and early basic-ultrabasic rock indirectly provides support for forming iron deposit; distribution of ore, which is irregular plate, lenticular shapes, branch and pinnate, is controlled by the contact zone and structural form. Based on the forecasting methods of metallogenic pattern, magnetic anomaly and abnormal electrical, the districts of Shuangjing, Dongjiao and southern fringe of Longjianggou are considered as the prospecting zone.
