河北省地球化学异常集中区及其分布规律

河北省地球化学异常具有成片集中分布的特点,依据主要成矿元素浓集特征可划分为十九个异常集中区.地球化学异常集中区的分布与地层、构造、岩浆岩的关系密切,在深部构造上则主要分布于幔坡区.综合研究表明,河北省的太古代地层区主要富集Au；中生代火山盆地区富集Pb、Zn、Ag、Mo;北东向的乌龙沟～上黄旗深断裂带是Pb、Zn、Ag、Cu、Mo、Au浓集区；东西向的大庙-娘娘庙深断裂主要发育铁族元素.建议今后在矿产勘查工作中注意这一规律.

GEOCHEMICAL ANOMALY GATHERED AREAS AND DISTRIBUTION REGULARITIES IN HEBEI PROVICE

Distributions of geochemical anomalies have characteristics of muster and concentration in Hebei province.According to distribution regularities of main ore-forming elements,19 geochemical anomaly gathered-areas are divided in Hebei.Anomaly gathered-areas have well relationship with the formations,structures,and igneous rocks,which gather mostly mantle slop area in deep tectonics.The study results show that Au is enriched in Archean strata areas,Pb,Zn,Ag,Mo are enriched in mesozoic volcanic basins,Pb,Zn,Ag,Cu,Mo,Au are enriched in Wulonggou-Shanghuangqi fault belt,and iron group elements are enriched in Damiao-niangniangmiao fault belt.The distribution regularities should be paid attention to for mineral exploration work in future.
