【摘要】：云南羅平富樂鉛鋅礦是川滇黔鉛鋅成礦域內(nèi)賦礦層位最新的大型鉛鋅礦床,成礦流體研究薄弱,鉛鋅成礦作用過程的認(rèn)識(shí)缺少實(shí)際地球化學(xué)依據(jù)。對(duì)該礦床及鄰近礦點(diǎn)中閃鋅礦流體包裹體的研究表明,該區(qū)礦床(點(diǎn))閃鋅礦中流體包裹體以氣液相包裹體為主,其次為含子礦物多相包裹體,顯微測(cè)溫獲得閃鋅礦流體包裹體均一溫度主要分布在120~160℃和180~210℃兩個(gè)區(qū)間,鹽度分布在4%~10%和16%~22%兩個(gè)區(qū)間,礦區(qū)存在低溫和中溫兩類成礦流體,該類流體屬于少量油田水混入的Na~+-Mg~(2+)-SO_4~(2-)-Cl~-型流體,結(jié)合富樂礦區(qū)礦體及礦石組構(gòu)特征分析,該區(qū)成礦流體具有低溫和中溫流體混合特征,在成礦流體混合部位形成富厚礦體。該成果為認(rèn)識(shí)該區(qū)鉛鋅成礦作用提供了新的地球化學(xué)證據(jù)。
[Abstract]:The Luo Ping Fule lead-zinc deposit in Yunnan Province is the latest large-scale lead-zinc deposit in the lead-zinc metallogenic region of Sichuan Yunnan and Guizhou Province. The study of ore-forming fluids is weak and the understanding of the process of lead-zinc mineralization is lack of practical geochemical basis. The study of sphalerite fluid inclusions in the ore deposit and adjacent ore points shows that the fluid inclusions in the sphalerite are mainly gas-liquid inclusions, followed by the multi-phase inclusions of sub-bearing minerals. The results of microthermometry show that the homogenization temperature of sphalerite fluid inclusions is mainly distributed between 120 ~ 160 鈩，
