| [摘要]普朗-红山铜多金属成矿亚带北部帕纳牛场辉锑矿床与石英二长斑岩( 热液) 及断裂有
关。斑岩黑云母40 Ar-39 Ar 坪年龄和等时线年龄分别为199郾1依1郾3 Ma 和199郾2依2郾4 Ma,代表了与辉锑
矿化对应的斑岩的侵位时间,是该成矿亚带上目前获得石英二长斑岩中40 Ar-39 Ar 最年轻的新年龄值,
代表了义敦岛弧普朗-红山铜多金属成矿亚带存在燕山早期的构造-岩浆活动。在印支晚期主要形成
斑岩型-夕卡岩型铜多金属矿床之外,燕山早期还具有斑岩及至少与斑岩有关的热液脉状成矿作用-锑
矿化,预示了本区斑岩的一种新的成矿作用和找矿方向与前景。 |

| Abstract:The stibnite deposit at the Panan cattle farm in the north of Pulang-Hongshan copper polymetallic metallogenic sub-belt is associated with
beschtauite (hydrothermal) and faults郾The 40 Ar-39 Ar plateau age and isochron age of the blackmica in porphyry are 199郾1依1郾3Ma and 199郾2依2郾4Ma,
which represent the emplacement time of porphyry corresponding to stibnite metallization郾These ages are the youngest ones of 40 Ar-39 Ar of beschtauite in
the Pulang-Hongshan copper polymetallic metallogenic sub-belt, which indicate that in this sub-belt of the Yidun arc existed early Yanshanian tectonomagmatic
activities郾In late Indo-China epoch, porphyry-skarn copper polymetallic deposit formed in this area, moreover in early Yanshaniann time there
was also porphyry deposit formed, as well as hydrothermal vein mineralization related with porphyry郾They indicate a new metallogenesis of porphyry, ex鄄
ploration direction and prospect in this region郾 |
