摘要:

在柴胡栏子金矿开展深部找矿研究,从野外原始资料收集入手,研究矿体形态特征,总结其赋存规律,完成了深部矿体的预测定位,经钻孔验证证实,取得了深部探矿突破性进展。对于深部矿体的预测定位,主要根据断裂及矿体赋存特征等地质条件分析判断,认为旋钮构造作用中心点,即不同走向矿体的交会结点的侧伏趋势即是矿体的侧伏趋势,矿体沿结点的侧伏方向向深部发育。由此确定了预测靶区:一是走向呈315°的矿体,预测重点部位在700 m标高以下18线以南到33线之间;二是走向呈近EW的矿体,预测重点部位在700 m标高以下5350线以东到5950线之间。通过钻孔验证,见矿率达59%,在预测靶区范围内共获得(333)黄金金属量4 511.39 kg,矿石量143.60万t。其中,1#矿体获得金属量713.84 kg,矿石量19.64万t;4#和8#矿体获得金属量3 797.55 kg,矿石量123.95万t。

Abstract:

Through research of deep prospecting in Chaihulanzi gold deposit,starting with raw data collecting from the field,focused on the ore body characteristics,summary its occurrence law,and then complete a position prediction of the deep ore bodies.The prediction had been verified by drilling confirmed was a deep prospecting breakthrough.The position of the deep orebody was judged mainly according to the geological conditions of the fault structure and the ore body characteristics analysis,the results showed that the lateral trending of center of the knob tectonic,the intersection of orebodies with different trends,is the lateral trending of the orebodies,the orebody developed to the deep along the direction of the intersection.Thus,we determined the predicted target:Firstly,a 315° trend orebody with key forecast positions below the elevation of 700 m,between south of 18 lines to 33 lines;secondly,a nearly EW trend orebody with the key predict positions below the elevation of 700 m between east 5350 line to 5950 lines.Drilling results verified that mineralization within the target range was good,obtaining a total of 4 511.39 kg of gold metal (333),1.436 million tons of ore.The 1# orebody had 713.84 kg of metal content,196 400 t of ore;4# and 8# orebody had a metal content of 797.55 kg,1.2395 million tons of ore,respectively.
