牟乳金矿带构造分区特征及找矿意义

Structural division characteristics and ore-prospecting

目的研究山东牟平—乳山(以下简称牟乳)金矿带构造控矿规律。方法利用波浪状镶嵌构造理论,对断裂带内矿床的分布特征和矿床(体)有利成矿部位进行了分析,总结了本区断裂控矿规律。结果本区控矿构造系统主要由近南北向容矿断裂和北西向构造条带组成;矿床就位主要受近南北向断裂与北西向构造带的联合控制,分布于其相交的构造结中;在每一良好的成矿段内,矿床的分布具近等距性。结论西泊地区为一矿床(点)赋存点。

Aim To research the structural ore-controlling rules in Mouru gold ore belt, Shandong. Methods On the basis of field study, use Crustal Wavy Mosaic Structure Theory to analyze features of deposits distribution and beneficial places for deposits, and sum up structural ore-controlling Characters. Results The structural ore-controlling system mainly consists of approximate north-south fractures and west-north structure belts, the place of the mineral bed is mostly controlled by above-mentioned fractures of two directions, and distribute at structural intersectant knots of approximate north-south fractures and west-north structure belts. In every good mineralized segment, space between of deposits is almost equidistant. Conclusion In addition to approximate north-south directional fractures, there are west-north directional fractured zones in controlling ore.
