摘要
简要介绍了河北省隆化县南部地质构造及区域化探异常特征,从成矿元素来源、富集沉淀以及导矿、储矿空间等方面分析了本区地质背景中有利的成矿因素,解译了区域化探异常对本区多金属成矿的有利指示。通过对区域上成矿地质条件相似的典型矿床进行成矿要素分析,阐述了本区如何利用现有的基础资料进行金-多金属找矿的思路,指出了本区找矿的主攻矿种及矿床类型,并总结了找矿标志。
In this paper, regional geological structures and geochemical anomalies in Longhua County of Hebei Province are introduced, the favorable ore -forming factors in regional geology are proposed, and the indicative function of regional geochemical anomalies for polymetallic prospecting are interpreted according to the source, enrichment and precipitation of ore - forming elements, and characteristics of the ore - transmitting and ore -depositing structures in the study area. By analyzing the metallogenic essential factors of typical deposits under similarity geological conditions in study area, the direction, mineral assemblage, deposit type, and criteria for gold- polymetallic prospecting are proposed.
