湖南祁东清水塘铅锌矿床流体包裹体研究
|
摘要
在野外地质调查基础上,本文通过湖南祁东清水塘铅锌矿床流体包裹体显微测温和激光拉曼探针成分,以及氢、氧同位素等综合研究,并参照前人研究成果,探讨清水塘铅锌矿床形成的物理化学条件。流体包裹体显微观察表明,不同矿物载体中流体包裹体发育程度不一,但以富液相两相水溶液包裹体为主。其中闪锌矿和方解石载体中的流体包裹体相对比较发育,数量较多;石英载体中包裹体不太发育,数量较少。流体包裹体显微测温显示闪锌矿、石英和方解石的均一温度分别为109~188℃、122~239℃和144~326℃,盐度分别为9.47%~20.97%,NaCleq.、0.18%~16.62%,NaCleq.和0.18%~7.31%,NaCleq.。闪锌矿的均—温度和盐度相对比较集中,其中富气相两相水溶液包裹体的气相成分主要为水蒸汽。含矿石英的氢、氧同位素的δD(H_2O,V-SNOW)值为-98.9‰~-79.3‰,δ~(18)O(H_2O,V-SMOW)值为-8.10‰~0.63‰,表明成矿流体以岩浆水为主,混有大气降水。以上研究表明清水塘铅锌矿床的成矿流体演化相对比较单一,成矿主要以混合作用为主。
Based on the field geological investigation,we study that microthermometry and micro-laser Raman microprobe compositions for fluid inclusion from the Qingshuitang Pb—Zn deposit,as well as hydrogen and oxygen isotopic compositions.With reference to previous research data,the physical and chemical conditions of the Qingshuitang Pb—Zn deposit are discussed.The microscopic observation shows that fluid inclusions are erratically developed in different minerals.There are more fluid inclusions occurring in sphalerite and calcite than quartz.It mainly consists of liquid-rich two-phase inclusions.Microthermometry shows that the homogenization temperatures of sphalerite,quartz,and calcite range from 109℃ to 188℃,122℃ to 239℃,and 144℃ to 326℃,respectively.Their salinities range from 9.47%to 20.97%,NaCl eq.,0.18%to 16.62%,NaCl eq.,and 0.18%to 7.31%,NaCl eq.,respectively,of which the homogenization temperatures and salinities of sphalerite are in a narrow range.Micro-laser Raman spectroscopy of sphalerite shows the gas phase of the fluid inclusions mainly consists of water vapor.SD(H_2O,V-SMOW) of ore-bearing quartz ranges from-98.9‰to-79.3‰,δ~(18)O(H_2O,V-SMOW)ranges from-8.10‰ to 0.63‰,indicating the ore-forming fluid was mainly derived from magmatic hydrothermal water,influenced by the meteoric water.The synthetical analytical results indicate that the Qingshuitang Pb—Zn deposit the evolution of the ore-forming fluid is simple and the mixing action is dominant during the mineralization process from the Qingshuitang Pb—Zn deposit.
