中文摘要:
      [摘 要] 通过对河南省嵩县土岭村钼多金属矿地质特征及成矿环境进行分析,认为土岭村钼多金属矿 有蚀变破碎带型和石英脉型两种。蚀变破碎带矿化以金为主,局部含钼,总体矿化较差;石英脉型在北部土岭 村一带以铅钼矿化为主,南部大西沟一带则以钼金矿化为主。矿体受三级火山机构、断裂及下伏的隐伏岩体 控制。石英脉型钼矿形成于熊耳晚期,为晚期火成岩岩浆热液沿早期流纹斑岩近水平节理及裂隙充填形成, 后期经下伏隐伏岩体形成的含矿热液叠加,出现铅钼矿化和金钼矿化。综合分析认为蚀变破碎带中的金钼矿 化较弱,找矿应以石英脉型矿化为主,同时应注重深部隐伏斑岩型钼矿的验证工作。
英文摘要:
      Abstract:Through the analysis on geological characteristics and metallogenic environment of the Tulingcun molybdenum polymetallic deposit in Songxian county of Henan province,it is suggested that this deposit can be classified into two types:altered crushed zone type and quartz vein type.Mineralization in the altered crushed zone is dominated by gold,with local molybdenum-bearing,which is poor as a whole. Mineralization in the quartz vein around northern Tulingcun consisting mainly of galenite and molybdenum,and the mineralization of the quartz vein around south of Daxigou is largely gold and molybdenum. Ore bodies are controlled by three-level volcanic apparatus, faults and underlying hidden rock bodies. Mineralization in the quartz vein formed during the late Xiong'er period,as a result of magma thermal fluids in volcanic rocks filling in horizontal joints and fissures of early rhyolite-porphyry. And afterwards Pb-Mo and Au-Mo mineralization occurred due to superimposition of ore-bearing thermal fluids from the hidden rock bodies. A comprehensive analysis suggests that the Au-Mo mineralization in the altered crushed zone is relatively weak,and the quartz vein is the preferred target for ore search. At the same time attention should also be focused on confirmation of concealed porphyry molybdenum deposits at depth.
