摘要
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 direct indicators,and lead clan placer anomalies and geochemical anomalies are indirect markers for ore search.Grasping the ore prospecting markers is an effective way for search of the deposits.Lots of lead-zinc ore-points have been found in the Diaoshigou area and its surroundings,showing a good prospect.And some new ideas for further survey in the region are proposed in this paper.
