吉林红旗岭铜镍矿床综合找矿模型

以矿区地质背景、含矿岩体地质特征为基础，分析了吉林红旗岭钢镍矿床的成矿过程。提出含矿岩体是受构造控制的海西期镁铁—超模铁质岩体，岩体具有轻稀土富集、重稀土亏损的特征的地球化学信息和低阻、高磁、高重力的地球物理异常等信息。结合地球化学与地球物理勘查方法建立了红旗岭钢镍矿床综合找矿模型，利用找矿模型评价了红旗岭矿区的岩体，确定沿老砬子-付家-黄瓜营子断裂带分布的镁铁-超模铁质岩体是找寻矿床的有利靶区。其中1号、7号岩体的深部应作为找寻大中型富矿岩体或隐代富矿岩体的有利靶区。

SYNTHESIS PROSPECTING MODEL OF COPPER-NICKEL DEPOSIT OF HONGQILING,JILIN PROVINCE

Based on the the geological setting and the geological characteristic of the ore -bearing rock body of copper-nickel deposit of Hongqiling in Jilin province, the in ineralization process was analysed. The information of geology, geochemica l and geophysical of ore-body proved that the main ore-bearing rock bodies are H ercynian mafic and utlramafic rock which is controlled by structure. This rock i s characteristic which are light REE enrichment and to the heavy REE deficiency geochemical and low-resistance, high-magnetism and high-gravity geophysically. S ynthesized geological, geochemical, geophysical prospecting methods, this paper founded the synthetic prostpecting model. According to this prospecting model wa s evaluated rock body of Hongqiling. It is believed that is the available prospe cting targets the mafic and utlramafic rocks along the fault belt of Laolazi-Fuj ia-Huangguayingzi. The depths of rock body No.1 and No.7 are the prospecting tar gets for prospecting larger-middle rock body of rich ore or burial rich ore.
