| 摘 要： | 掉石沟铅锌矿是敦煌地块南缘代表性的叠加改造层控夕卡岩型矿床。矿床赋存于敦煌岩群第二岩组第二岩段的大理岩、石榴石透辉石夕卡岩及石墨斜长变粒岩、蚀变碎裂岩中,矿石类型主要有夕卡岩型、蚀变碎裂岩型、石英脉型、石墨斜长变粒岩型,有用组分主要为Pb、Zn。铁锰帽及石墨斜长变粒岩是矿床的直接找矿标志,铅族重砂异常及化探异常是间接的找矿标志。准确把握矿床的找矿标志是寻找该类矿床有效途径,目前已在掉石沟外围发现多处铅锌矿点,说明在掉石沟铅锌矿区及外围地区具有良好的找矿前景,进而提出了进一步找矿的新思路。

| Abstract: | The Diaoshigou lead-zinc deposit is a typical skarn deposit controlled by superposition and reformed strata in the southern margin of the Dunhuang block.It occurs in the marble,garnet-diopside skarn,graphite plagiogranulite,and altered cataclastic rock of the second section,second group of the Dunhuang rock-group.The ore types include skarn,altered chipped rock,quartz vein,and graphite plagiogranulite types,with useful compositions of Pb and Zn.Iron and manganese caps and graphite plagiogranulite are the di... |
