【摘要】：在野外地質(zhì)調(diào)查基礎(chǔ)上,本文通過湖南祁東清水塘鉛鋅礦床流體包裹體顯微測溫和激光拉曼探針成分,以及氫、氧同位素等綜合研究,并參照前人研究成果,探討清水塘鉛鋅礦床形成的物理化學條件。流體包裹體顯微觀察表明,不同礦物載體中流體包裹體發(fā)育程度不一,但以富液相兩相水溶液包裹體為主。其中閃鋅礦和方解石載體中的流體包裹體相對比較發(fā)育,數(shù)量較多;石英載體中包裹體不太發(fā)育,數(shù)量較少。流體包裹體顯微測溫顯示閃鋅礦、石英和方解石的均一溫度分別為109~188℃、122~239℃和144~326℃,鹽度分別為9.47%~20.97%,NaCleq.、0.18%~16.62%,NaCleq.和0.18%~7.31%,NaCleq.。閃鋅礦的均—溫度和鹽度相對比較集中,其中富氣相兩相水溶液包裹體的氣相成分主要為水蒸汽。含礦石英的氫、氧同位素的δD(H_2O,V-SNOW)值為-98.9‰~-79.3‰,δ~(18)O(H_2O,V-SMOW)值為-8.10‰~0.63‰,表明成礦流體以巖漿水為主,混有大氣降水。以上研究表明清水塘鉛鋅礦床的成礦流體演化相對比較單一,成礦主要以混合作用為主。
[Abstract]:On the basis of field geological survey , the physical and chemical conditions of fluid inclusions in the Pb - Zn deposit in Qingshuangtang , Qidong , Hunan were studied . The physical and chemical conditions of fluid inclusions in Qingshuangtang Pb - Zn deposit were discussed . The fluid inclusions in the sphalerite and calcite support were relatively developed and the quantity of fluid inclusions was relatively small . The temperature of inclusions in the sphalerite and calcite was 109 锝，
