福建大田地区多金属矿地质特征及找矿方向

Geological Characteristics of the Polymetallic Deposit and Prospecting Direction in Datian County,Fujian Province

大田地区主要出露古生代至晚侏罗世地层,以海相、海陆交互相、陆相沉积岩为主,极少量火山岩。区内构造发育,主要有北北东向复式背斜以及各类断裂构造。燕山早期岩浆侵入活动频繁而强烈,于褶皱中心(轴部)分布大面积花岗岩类侵入岩。通过该区铁、铅锌、铜矿化成矿及分带特征分析,为进一步找矿提供指导方向。

Paleozoic to late Jurassic strata formation are exposed in the the marine, sea-terrigenous and terrigenous sedimentary rocks wi Da th tian county. There few volcano rock. are The NNE anticline and all kinds of faults are developed in the area. The magma intrusion activity is frequent and intense in Yanshan early and there is a lare-area granite intrusive rock in the fold center. Based on the analytical results of mineralization metallogenic and zoning charac- teristics of the iron, zinc, copper ores, these can provide the direction for further prospec-
