| 中文摘要: |
| 江西省村前夕卡岩+斑岩复合型铜铅锌矿床产于燕山中期超浅成花岗斑岩与上石炭统黄龙-船山组白云质灰岩、白云岩接触带及其附近,具有接触带、斑岩体内成矿的特点.NE向村前倒转倾伏背斜轴部及倒转翼与岩体接触部位是矿区有利的成矿部位.矿体形态总体为不规则似层状,沿走向、倾向皆有膨大与收缩现象,倾角15°~68°.矿化主为铜铅锌.花岗斑岩、接触面的产状、围岩的夕卡岩化蚀变是矿化富集的主要控制因素.研究表明,含矿热液主要来自于上地幔,矿床成因类型属“夕卡岩+斑岩复合型”. |
| 英文摘要: |
| The composite Cunqian skarn+prophyry Cu-Pb-Zn deposit in Jiangxi province is located at contact of Middle Yansanian super-shallow granite and dolomitic limestone and dolomite of Upper Carboniferous Huanglong-Chuanshan formation.The ore deposit is characterized by ore bodies occurring both in the contact and within the porphyry body.The axis and limbs of Cunqian overturn plunging anticline are favorable for ore formation.Ore bodies are generally in irregular layeroid and swell and contract both in directions of strike and dip and the dip angle is 15°-68°.The mineralization is dominated by Cu,Pb and Zn.Granite,attitude of the contact plane,skarnization of the wall rock are control factors of mineralization.Studies on the deposit show that the ore fluid is mainly derived from upper mantle and it is genetically a skarn+ prophyry Cu-Pb-Zn deposit. |
