棉花坑矿床9号带南段不同标高矿体变化规律及成矿环境探讨
Discussion on the elevation change pattern and metallogenic environment of ore bodies in southern zone 9 of Mianhuakeng deposit
摘要
Abstract
The southern section of Zone No.9 in Mianhuakeng deposit is located in the middle of the Zhuguang pluton,which is a rich in uranium.The fault zone has undergone multiple tectonic and hydrothermal action,forming the favorable space for uranium mineralization and storage.Through secondary development and utilization of data from previous exploration projects,this paper analyzes the change patterns of the ore bodies at different elevations in the southern section of Zone 9 by the statistics on grade and thickness.The results indicate that the ore body trend to be rich in the depth but remain stable in thickness on the whole with local widening.The occurring frequency of moderate and high-grade ore segments are increasing in the deep,which may be caused by the reduction environment in the deep.This understanding provides clues and basis for the next uranium predicting and prospecting.关键词
