Aliben lead-polymetallic deposit is a quartz vein-altered in type��occurred in gneiss strata of Wulashan group�� The mineralization is dominated by lead with accompanying copper��gold��zinc and silver�� Two metallogenic stages can be classified that the early stage is the disseminated-Veinlet disseminated copper-lead-zinc type and subsequent galena-sphalerite-quartz veins in the late stage�� The study of fluid inclusion shows that aqueous twophase and gas-rich fluid inclusions developed in quartz of the early mineralization stage��the homogenization temperature varies from 281. 6�� to 357. 6 �� and 343. 5 �� to 351. 4 �棬salinity varies from 4. 18 to 9. 60 wt% NaCl and 1. 05 to 1. 90 wt%NaCl�� For the second mineralization stage��aqeous two-phase fluid inclusions are dominant type in��developed in quartz with the homogenization temperature ranging from 152. 6 �� to 335. 8 �棬and salinity ranging from 2. 74 to 8. 55 wt%NaCl�� Comprehensive study shows that the ore-forming fluids in the early mineralization stage mainly came from magmatic activity with meteoric water involved in later stage�� The deposit is middletemperature magmatic and hydrothermal in origin��
