新疆阿希金矿控矿因素三维定量分析与提取
|
摘要
新疆阿希金矿自20世纪90年代投产至今,地表矿、浅部矿已开采殆尽。采用三维空间分析方法提取控矿因素并进行成矿预测是发现深部隐伏矿体的一条有效途径。通过阿希金地质体三维建模,采用距离场分析、地质界面坡度分析以及地质界面趋势-起伏分析方法,提取了控矿主断裂面距离场、主断裂面坡度、主断裂面趋势-起伏、管道相距离场、管道相趋势-起伏5个控矿因素,并通过散点图对矿化指标与控矿因素的关联关系进行分析,得到各个因素的矿化富集空间,提取出成矿有利部位。分析结果可为阿希金矿的深部隐伏矿体三维预测提供成矿信息支持。
Axi gold deposit in Xinjiang began its production in the 1990 s.Till now,its surface and shallow ores have been almost exhausted.It is an effective way of discovering deep-seated concealed ore bodies to extract ore-controlling factors by 3D spatial analysis method and then to make metallogenic prognosis.This work used 3D modelling and adopted distance field analysis,slope analysis of geological interface and trend-undulation analysis of geological interface to extract five ore-controlling factors,including distance field factor of main faults,slope factor of main faults,trend-undulation factor of main faults,distance field factor of volcanic conduit facies and trendundulation factor of volcanic conduit facies.In addition,we analyzed the relationship between mineralization index and ore-controlling factors by scatter diagrams,got the mineralization enrichment space of each factor and extracted the favorable mineralization location.This conclusion can provide information support for 3D metallogenic prediction of deep concealed ore bodies in the Axi gold deposit.
