摘要 内蒙古克什克腾旗油房西矿区为中型银多金属矿床,伴生的铅锌、铜、钼可形成独立矿体。银铅锌与铜、钼矿化在水平和垂直方向都呈现出较明显的分带现象,即银、铅锌遍布全区且主要集中在浅部,钼、铜主要赋存在矿区中部和深部。通过2个较深钻孔的探索,在深部出现较普遍的与斑岩型矿床蚀变、矿化特征类似的钼(铜)矿化,且矿(化)体形态呈层状-似层状产出趋势明显。在位于西拉木伦河断裂以南的小东沟—库里吐地区,通过分析矿区成矿地质条件和矿化特征,初步认为本区钼矿化范围较大,矿床成因类型好,矿化空间保存完整,因而具有中型以上钼矿床的找矿潜力。 Youfangxi is a medium size Ag polymetallic deposit in Inner Mongolia. In the deposit occur not only independent silver, lead.zinc.copper ore bodies but also molybdenum ore bodies. The mineraliza- tion shows obvious horizontal and vertical zoning. Silver.lead and zinc mineralization spread all over the deposit area and mostly concentrate in the shallow depth. Copper and molybdenum are to depth in the cen- tral deposit area. Holes are generally drilled to 700 m elevation revealing silver, lead.zinc.copper and mo- lybdenum all in veinlike ore bodies. However, two deep drill holes show characteristic alteration and min- eralization of porphyry molybdenum (copper) deposit and the mineralization tend to be stratiform or layeroid. The deposit is located in the Xiaodonggou-Kulitu Mo potential area in the south of the Xilamulun River rift. According to the metallogenic geological conditions and mineralization i. e. mineralization in large area, well preserved mineralization space Youfangxi is potential for prospecting medium sized Mo de- posit.
