摘要
鱼池岭斑岩型钼矿是东秦岭新发现的超大型钼矿床,矿体赋存于合峪岩体童子庄复式花岗岩体和隐爆角砾集块岩中。矿体呈似层状、不规则的穹丘体状。矿石类型以辉钼矿矿石、黄铁矿-辉钼矿矿石为主。钼矿化主要呈细脉浸染状、细脉状、浸染状产出;矿化与脉体发育程度呈正相关。围岩蚀变具有分带特点:从隐爆角砾岩体向外,蚀变表现为钾化-石英绢云母化-粘土化分带。成矿经历了岩浆期、透岩浆流体期。该区燕山期斑岩岩株、隐爆角砾集块岩体是主要的找矿标志;合峪岩体及相类似岩体是今后找矿方向。
Yuchiling porphyry Mo deposit is a newly discovered super large scale deposit in the East Qinling Mountains,and the ore-bodies occur in Tongzizhuang composite granite of Heyu rock body and crypto-explo-sive brecciated agglomerate.The ore-bodies are in stratoid structure or irregular dome structure.The ores are mainly composed of molybdenite and pyrite-molybdenite.The mineralization of molybdenum occurs in veinlet disseminated structure,veinlet structure,or disseminated structure.The mineralization is positively correlated with the growth of veins.The alteration of wall-rocks is characterized by zoning:from the crypto-explosive breccia outward,the alteration occurs in forms of potassic alteration,quartz-sericitization and argil-lation respectively.The ore-forming process includes magmatic stage and transmagmatic fluid stage.The oc-currence of Yanshanian porphyry-type stocks and crypto-explosive brecciated agglomerates are the primary clues for prospecting.Heyu rock bodies and similar rock bodies are the prospecting direction in the future.
