福建大田武陵——漳平彭炉地区铁矿成矿规律及找矿方向分析

Analysis on Metallogenic regularity Controlling Stucture and Prospecting Direction of the Wuling Datian-Penglu Zhangping Area in Fujian Province

大田武陵—漳平彭炉位于福建龙岩马坑—大田汤泉铁矿整装勘查区内,区内铁矿成矿类型为沉积-改造型和矽卡岩型,与铁矿有关的地层有经畲组、船山-栖霞组、溪口组等。综合2种类型的成矿特征,分析了该区地层、复式背斜构造、侵入岩与铁矿成矿的关系,结合地层、构造、侵入岩分布情况及磁异常特征,圈定了5个具有找矿潜力的靶区,分析其找矿潜力。

The Wuling Datian-Penglu Zhangping Area is located in the the integrated exploration area of iron ore in Longyan Makeng-Datian Tangquan, Fujian. In this area. The iron ore de- posit type are sedimentary and transformation type and skarn type. The iron related stratas are By Yu group, Qixia group, Xikou Chuanshan group etc. By comprehensively analysising two types of mineralization features, the formation of this region, compound structure of the complex, and the relationship between intrusive rock and iron mineralization; according to the distribution of strata, structure, intrusion and magnetic anomalies of the region, Five ways to find the iron are put forward, 5 target ares of the 5 ore potential are potinted out, and their potential are analysised.
