摘要
以新疆哈密一碗泉铜镍矿区为研究对象,开展地面大比例尺高精度磁测和激电面积测量等工作,快速圈定隐伏蚀变矿化异常区,结合矿石质量分析、岩体含矿性和蚀变程度及物性测量数据,勾勒出隐伏蚀变岩体范围。通过对资料综合分析,圈定由磁力正异常、中高极化率异常、中低电阻率异常组成的具蚀变矿化超基性岩“三高一低”异常部位为找矿靶位,初步建立该区地质-地球物理等综合找矿标志,取得较理想的探矿效果。该研究为本区铜镍矿床深部勘查、资源潜力评估和下一步工程验证提供了可靠依据。
This study focuses on the Yiwangquan copper-nickel mining area in Hami,Xinjiang.It conducted high-precision ground magnetic surveys and induced polarization area measurements,swiftly delineating concealed alteration mineralization anomalies.Combining detailed analyses of ore quality,rock mineralization,alteration extent,and physical property measurements,the hidden alteration rock body boundaries were outlined.Through comprehensive data analysis,areas characterized by magnetic positive anomalies,medium to high polarization anomalies,and medium to low electrical resistivity anomalies,collectively referred to as the“three highs and one low”anomalies associated with alteration mineralization in ultrabasic rocks,were identified as prospective exploration targets.This study has established preliminary geological-geophysical exploration criteria for the region,yielding satisfactory exploration results.This research not only guides deep exploration efforts for copper-nickel deposits in this area but also provides a reliable basis for resource potential assessment and future project validation work.
