摘要:
论述了夹皮沟主要成矿带——NW向大型韧性剪切带及与其伴生的次一级NE向构造带(即本区矿床)的基本地质条件,尤其论述了本区矿床主控矿构造(NE向控矿构造)以外的次一级SN向控矿构造,及其金矿化体(石英脉)的具体特征、围岩蚀变和成矿规律等。找矿研究表明,本区矿床深部及原采区两侧的SN向矿体同样具有较大的成矿潜力。因此,夹皮沟本区矿床成矿带深部及两侧的SN向矿体应具有良好的成矿远景。
关键词: 金成矿带, 地质特征, 成矿条件, 找矿远景, 夹皮沟金矿床
Abstract:
We discuss the ore-formation function in Jiapigou gold mine,ore-formation belt is closely related to the Archean metamorphic rocks,mantle-derived magmatism and ductile shearing.The ore-formation fluid is mainly mantle fluid and the ore-formation materials mostly come from mantle.The ductile shearing belt are not only the migration channel of ore-information fluid,through mantle activity and its concomitant secondary fault structure,but the advantage space of ore-body emplacement.We discuss the basic geological conditions,under which the main part of Jiapigou gold mine becomes a large northwestward ductile shearing belt and its concomitant secondary formation belt,northeastward formation belt(i.e. the ore bed in this area),are widely distributed Archean metamorphic rocks,molten magma and dike,and strong ductile-brittle structure activity,the gold mineral body (quartz vein) is controlled by the secondary fracture on the both sides of the ductile shearing belt, and wall rock alteration is sericite-quartz alteration,silicification,chloritization and pyritization.The ore-exploration study demonstrates the deep part of the mineral bed in this area,has the same large ore-formation potentiality,so the deep part of mineral-bed ore-formation belt in Jiapigou area should be a good ore-formation prospect (the second ore-formation bench).
Key words:  , Gold ore-formation belt;Geological characteristics;Ore-formation conditions;Ore-exploration prospect;Jiapigou gold deposit
