封开县糯米河金矿床找矿标志及找矿远景评述

Evaluation and Discussion of Prospecting Indicator and Prospecting Prospect of Nomihe Gold Deposit in Fengkai County

为寻找封开县糯米河金矿床周边类似金矿床及评述该金矿床深部找矿潜力,通过对封开县糯米河金矿床成矿地质背景、矿床特征进行多方面的研究,认为该金矿体严格受北东向构造带及后期不同方向叠加构造控制,含矿地层为震旦系坝里组。含矿岩性及围岩蚀变、化探异常、构造等为其重要找矿标志;区域成矿条件良好,通过“源-运-储”成矿条件分析,矿区深部找矿潜力巨大。

In order to search for similar gold deposit around the Nomihe gold deposit in Fengkai County and evaluate the prospecting potential of the deeper part of the deposit,through the study of the metallogenic setting and the characteristics of the Nomihe gold deposit in Fengkai County in various perspectives,it is concluded that the gold ore body is strictly controlled by the north-east tectonic zone and the superimposed structure in different directions at a later stage,and the ore-bearing stratum is the Damli Formation of Sinian system.The ore-bearing lithology,wall rock alteration,geochemical anomalies and tectonics are important prospecting indicators.The metallogenic conditions of the region are good,and through the analysis of the"source-transport-storage"metallogenic conditions,it shows that the deep part of the mine has great prospecting potential.
