陕西省山阳县夏家店金(钒)矿地质特征、成矿模式与找矿预测

Geological Characteristics,Metallogenic Model and Prospecting of XiajiadianGold-vanadium Deposit in Shanyang County,Shaanxi Province

夏家店金矿床处于区域性山阳-凤镇、镇安-板岩镇深大断裂交汇复合构造较为复杂且强烈的特殊位置,含矿岩系为寒武系水沟口组薄互层重晶石-碳-泥-硅质板岩、泥质岩、硅质岩,容矿构造为脆-韧性断裂,属于与黑色岩系有关的金矿床。经多年勘查,矿床控制金、钒资源量均达中型规模。矿石类型可分为板岩角砾岩型、硅质角砾岩型、白云岩角砾岩型和混合角砾岩型4种类型。笔者详细介绍了主要矿体的地质和矿化特征,在总结矿床地质、地球化学、流体包裹体和同位素特征的基础上,进一步建立了成矿模式和找矿标志,并指出了苏岭沟和Ⅶ号矿化带倒转背斜槽部是进一步找矿工作的重点地段。

Xiajiadian gold deposit is located in Fengzhen fault and Zhen＇an-Banyanzhen fault. a special complex intersection between Shanyang- The ore-bearing rocks are thin interbed barite-ear- bonaceous-argillaceous-siliceous slate, argillaceous rock and siliceous rock of Cambrian Shuigouk ou formation. The ore-bearing tectonic is brittle-ductile fault related to the black rock series Based on years of exploration, the quantity of gold and vanadium resources both reach a medium scale. Ore types type and combin can be divided into. slate-breccia type, siliceous breccia type, dolomitic breccia ed breccia types. In this paper, we introduce in details the geological and mineralization characteristics of the main ore bodies. Based on summarizing the characteristics of depos it geology, geochemistry, fluid inclusion and isotope, the metallogenic model and prospecting marks are established in further. Sulinggou and the reversal anticline slot part of Ⅶ mineralized belt are the key sections for exploration work in the future.
