摘要:

苦海南多协龙地区位于西秦岭成矿带苦海—作母沟Hg-Au-Pb-Zn-Sb-W成矿亚带,该成矿亚带内分布着多个大中型金多金属矿床,显示出巨大的找矿潜力。利用1∶1万土壤地球化学测量对苦海南多协龙地区的地球化学特征进行了初步分析,对元素分布特征、Au异常特征、综合异常特征进行了研究。结果显示,Au异常分布不均匀,离散程度较大,为苦海南多协龙地区的有利成矿元素。根据元素组合特征及成矿地质条件,圈出综合异常7处,并对AP5综合异常进行了工程验证,取得了较好的找矿效果,探获了矿化体4条、矿体3条。探矿结果表明,苦海南多协龙地区利用土壤地球化学测量找矿是有效的,也证明了该地区具有较好的找金前景。

Abstract:

Duoxielong Area of Southern Kuhai is located in Kuhai-Zuomugou Hg-Au-Pb-Zn-Sb-W metallogenic subzone of West Qinling Metallogenic Belt,which hosts multiple large and medium-sized gold polymetallic deposits,showcasing significant prospecting potential.A 1∶10 000 soil geochemical survey was conducted to preliminarily analyze the area’s geochemical characteristics,focusing on the characteristics of element distribution,Au anomalies,and composite anomalies in Duoxielong Area of Southern Kuhai.The results reveal uneven Au anomaly distribution with high dispersion,identifying gold as a favorable metallogenic element in the area.Based on element associations and metallogenic geological conditions,
