佳木斯－牡丹江地区砾岩型金矿成矿特征及找矿预测

THE METALLOGENIC FEATURES AND PROSPECTING PROGNOSIS OF THE GOLD DEPOSITS HOSTED IN CONGLOMERATES IN THE JIAMUSI-MUDANJIANG REGION

在全面分析区域地质背景和区内其它类型金矿特征基础上，以区内小金山、平岗、四方台、石头河等金矿为典型实例，重点研究了侏罗系穆棱组、第三系道台桥组、八虎力组砾岩型金矿床地质特征。通过侏罗纪、第三纪古地理恢复，古砂金分布与岩相关系对比，遥感线性构造与古河道关系研究和遥感找矿标志建立等，进一步总结成矿规律，厘定成矿模式，进行找矿预测。

Based on the analysis of regional geological background and other types of gold deposits, the Xiaojinshan, Pinggang, Sifangtai and Shitouhe deposits are typically exemplified to express the geological features of conglomerate-type gold deposits hosted in the Muling Group of Jurassic System, the Daotaiqlao and Bahuli Groups of Tertiary System. The ...t.r.ti.. ofthe Jurassic and Tertary paleogeography and comparison of distribution of paleoplacer with lithofacies are included in this paper. Inaddition, combined with the relation of linear structure of remote sensing images to paleoriver vally, the ore guides of remotesense and the metallogenlc regularity have been summahzed, the metallogenic model been established, and the prospecting prognosis been made.
