摘要
洪武村金矿位于扬子准地台上扬子台坪鄂中褶断区黄陵断穹核部中段,分布于区域性深大断裂——板仓河断裂北东侧次级脆韧性断裂破碎带内。金矿体及矿化均产于一组走向北—北北西向断裂破碎带中;矿体呈脉状、透镜状产出;主要矿石类型为含Au蚀变构造岩型,次含Au硫化物石英脉型。含矿破碎带及顶底板围岩均有不同程度的构造热液蚀变,主要为绢云化、硅化、黄铁矿化,属岩浆期后中低温热液蚀变型金矿,具较好的找矿前景。
Gold deposit in Hongwu village is located in middle of the core of Huangling faulted dome in fault fold zone , Hubei Province, distributed in regional deep fauh-Bancanghe fault of notheastern second-order brittle-ductile fault frac- ture zone. Gold ore bodies and mineralization are produced in N-NNW trending fault fracture zone. The orebody appears in veinlike and lenticular shapes. Ore-bearing fractured zone and roof ＆ floor surrounding rock have different degrees of structure hydrothermal alteration, mainly as sericitization, silicification, pyritization, belongs to medium-low hydrothermal altered gold deposit in magmatic stage,with good ore prospects.
