Using fluid inclusion petrography and microthermometry , the thesis embarks further studies on questions such as the physical and chemical conditions of the ore - forming processes , the evolving characteristics of ore - forming fluid at time and space , the origin of ore - forming fluid 本文利用流體包裹體的手段,對銀山礦床成礦物理化學(xué)條件、成礦流體的時(shí)空演化特征、成礦流體來源做了較為深入的研究,在此基礎(chǔ)上,討論了礦質(zhì)沉淀機(jī)制及礦床成因。
Based on the studies of microthermometry , gas composition , liquid composition , rare earth elements , ore - forming elements and 13c , d , 18o of fluid inclusions from the mineralization district and the representative deposits , such as zacun gold deposit , shuixie copper - cobalt deposit , shiyancun stibium deposit and bijiashan stibium deposit , two metallogenic fluid systems have been distinguished , i . e . , zijinshan metallogenic fluid system and gonglang metallogenic fluid system in weishan - yongping mineralization district 礦化集中區(qū)及扎村金礦、水泄銅鈷礦、石巖村銻礦、筆架山銻礦等典型礦床流體包裹體的顯微測溫、氣相成分、液相成分、稀土元素、重金屬元素及~ ( 13 ) c , d , ~ ( 18 ) o穩(wěn)定同位素的研究表明,云南巍山-永平地區(qū)銅金多金屬礦化集中區(qū)存在兩個(gè)成礦流體系統(tǒng):紫金山背斜成礦流體系統(tǒng)與公郎弧成礦流體系統(tǒng)。
