新疆萨热阔布金矿床特征及隐伏矿预测新途径的思路
|
摘要
萨热阔布金矿床产于下泥盆统康布铁堡组海相火山 -沉积岩中 ,火山热水沉积作用形成了金的预富集 ,后期挤压剪切作用使金富集成矿。金矿找矿预测标志为有关层位、断裂、蚀变、金属元素组合、高钾侵入岩及物化探异常。提出通过进一步研究控矿规律 ,确定蚀变分带和矿体空间展布特点 ,运用浅层地震法、电磁法、构造叠加晕、流体晕、遥感信息强化技术 ,实现隐伏金矿找矿预测的思路
Sareuobu gold deposit is located in lower Devonian system Kangbutiebao group marine facies volcano sedimentary rock.Volcanic hotwater sediment formed gold priliminary enrichment and extrusion shear action formed gold mineralization finally.Gold exploration marks are stratohorizon,faults,alterations,anomaly element assemblage,high potash intrusive rock.TEM geophysical and soil geochemical anomalies are important evaluation index.To predict buried gold deposit,It is advanced to research deposit controlling regularity,define alteration zone and orebody distribution,use shallow seismic exploration,electrical magnetic prospecting,tectonic superimposed anomaly,fluid anamoly and remote sensing alterational information.
