在豫西熊耳山地区马超营断裂带中段新近探明的石瑶沟大型斑岩型钼矿,与周围的脉型金矿床构成了狮子庙金钼矿田。斑岩钼矿与外围分布的脉状金矿(铅锌银)具有明显的时空关系,钼-金矿化与燕山期隐伏花岗斑岩体关系密切。石瑶沟斑岩钼矿的外围有一些脉状金矿发育,伴生铅锌银矿,产于斑岩钼矿外围围岩断裂内。这种钼与金矿的密切时空分布关系构成一个很好的成矿系统,斑岩钼矿与金矿互为找矿的指示标志。通过建立矿床模型,在详查过程中取得了很好的找矿效果,对区域找矿具有一定的借鉴意义。
在豫西熊耳山地區馬超營斷裂帶中段新近探明的石瑤溝大型斑巖型鉬礦,與週圍的脈型金礦床構成瞭獅子廟金鉬礦田。斑巖鉬礦與外圍分佈的脈狀金礦(鉛鋅銀)具有明顯的時空關繫,鉬-金礦化與燕山期隱伏花崗斑巖體關繫密切。石瑤溝斑巖鉬礦的外圍有一些脈狀金礦髮育,伴生鉛鋅銀礦,產于斑巖鉬礦外圍圍巖斷裂內。這種鉬與金礦的密切時空分佈關繫構成一箇很好的成礦繫統,斑巖鉬礦與金礦互為找礦的指示標誌。通過建立礦床模型,在詳查過程中取得瞭很好的找礦效果,對區域找礦具有一定的藉鑒意義。

The Shiyaogou deposit is a large Molybdenum deposit,which is newly explored in the middle part of Machaoying fault zone,in Xiong'ershan area of western Henan Province,and it constitutes the Shizimiao Au-Mo orefield with the surronding vein-type Au ore deposits.The Shiyaogou porphyry Mo deposit obviously has a close relationship with these vein-type Au deposits both in space and time,and the Au-Mo mineralization in Shizimiao orefield is closely related to the activity of the Yanshanian concealed granite-porphyry bodies.The vein-type Au ore deposits accociated with Pb-Zn-Ag,occur in the fault zones of the surronding rocks outside the Shiyaogou Molybdenum deposit.The close distributed relationship form a big metallogenic system,the Mo deposit and the vein-type Au deposit are indicator signs for prospecting each orther.By the mineral deposit model building,a good prospecting result is obtained,and it shows a certain guiding significance to the regional prospecting.
