摘要
本文简述了河北北部地区某些脉状金矿床的“三层楼”分布特征。并研究了本类型金矿床的结构形态和地球化学分带性。简要描述了它产出的地质构造环境和成矿作用机制,最后给出地球化学预测指标。对本区寻找和预测“三层楼”金矿床具有一定的指导意义。
In this PaPer, the distribution feature, occurrence environment and minerogenic mechanism of the 'three-layer -structure'model of vein gold ore in North Hebei's vein gold dePosit are briefly described. The geological structure and geochemical zoning feature of such tyPe gold ore are studied.As a result, the geochemically Prognostic index-is given which is of a certain gui-ding significance for Prospecting such tyPe gold in this district.
