广西河池五圩矿田箭猪坡铅锌锑矿位于江南古陆南缘、右江再生地槽北部边缘的丹池多金属成矿带南端,成矿作用和断裂构造密切相关,矿体主要受 NNW向断裂带控制,呈脉状、条带状、块状、角砾状产出。矿石中金属矿物除闪锌矿、方铅矿、辉锑矿等常见硫化物之外,还大量发育脆硫锑铅矿、硫锑铅矿等硫盐矿物;非金属矿物主要为石英、绢云母、锰方解石、方解石及锰白云石,矿床的形成经历了中低温热液充填成矿期。文章在总结前人的认识基础上,依据野外调查及镜下光(薄)片的观察,并根据矿物共生组合及相互穿插关系,分成2个成矿期4个主要的成矿阶段及12个亚阶段,成矿期包括热液成矿期及表生期,其研究结果不仅有助于了解矿化过程,而且为矿床评价、组分综合利用和选冶提供重要依据。
廣西河池五圩礦田箭豬坡鉛鋅銻礦位于江南古陸南緣、右江再生地槽北部邊緣的丹池多金屬成礦帶南耑,成礦作用和斷裂構造密切相關,礦體主要受 NNW嚮斷裂帶控製,呈脈狀、條帶狀、塊狀、角礫狀產齣。礦石中金屬礦物除閃鋅礦、方鉛礦、輝銻礦等常見硫化物之外,還大量髮育脆硫銻鉛礦、硫銻鉛礦等硫鹽礦物;非金屬礦物主要為石英、絹雲母、錳方解石、方解石及錳白雲石,礦床的形成經歷瞭中低溫熱液充填成礦期。文章在總結前人的認識基礎上,依據野外調查及鏡下光(薄)片的觀察,併根據礦物共生組閤及相互穿插關繫,分成2箇成礦期4箇主要的成礦階段及12箇亞階段,成礦期包括熱液成礦期及錶生期,其研究結果不僅有助于瞭解礦化過程,而且為礦床評價、組分綜閤利用和選冶提供重要依據。

Jianzhupo Pb-Zn-Sb deposit in Hechi of Guangxi was located at the south end of Danchi metallogen-ic belt which lay atthe south rim of Jiangnan ancient land and the northern edge of Youjiang rejuvenated geo-syncline.The mineralization was closely related to and fracture structures,and the orebodies were mainly controlled by NNW trending fracture belt with occurrences of veined,banded,massive and breccia forms. Besides metallic minerals such as sphalerite,galena,stibnite and other common sulfides,the sulfosalt miner-als like j amesonite and boulangerite in large amount were found in the ores.Nonmetallic minerals contained mainly included quartz,sericite,calcimangite,calcite and manganese dolomite.The deposit had under gone through low-to-moderate hydrothermal filled metallogenic period.Based on the previous studies of predeces-sors and the author’s field survey and observation on polished thin section sunder microscope,and in light of mineral paragenetic association and interfingering relationship of ore veins,this paper divided the mineraliza-tion process into two metallogenic periods,or four mainmetall ogenicstages or 1 2 sub-stages.The metallo-genic periods included hydatogenesis period and supergene period.The research results of this paper not only were conducive to a better under standing of the mineralization process,but also provided the deposit assess-ment,comprehensive component analysis and dressing and smelting process with an important basis.
