The early naturalists showed considerable attention and interest in these large inclusions (Dewey, 1818。 Alderton, et al., 1985, A Pratical Guide to Fluid Inclusion Studies, Chapman and Hall (有中譯本） ★ 劉斌，朱思林，沈 崑， 2020，流體包裹體熱力學(xué)參數(shù)計(jì)算軟件及算例 ★ 盧煥章， 范宏瑞，倪培，張文淮，等， 2020，流體包裹體，科學(xué)出版社 FLUID INCLUSIONS 第一章 概述 1 礦物中的包裹體及研究歷史 （ 1） 概念 （ 2） 研究歷史 2 流體包裹體研究領(lǐng)域研究 （ 1） 礦物學(xué) 、 巖石學(xué) 、 礦床學(xué)領(lǐng)域的成巖成礦研究 （ 2） 成礦預(yù)測(cè)及資源遠(yuǎn)景評(píng)價(jià) （ 3） 材料 、 人造晶體 、 寶石等方面研究 3 包體礦物學(xué)的數(shù)據(jù)類型及其意義 （ 1） 溫度； （ 2） 壓力； （ 3） 鹽度； （ 4） 成分； （ 5） Ph、 Eh…… .. 1 礦物中的包裹體及研究歷史 (1) 礦物中的包裹體 With the notable exception of those crystals in metamorphic samples that have grown in the solid state, all crystals in all terrestrial and extraterres trial samples have grown from some kind of fluid. The minerals of many meteoritic and lunar samples, and of terrestrial igneous rocks, have grown from fluid silicate melts(硅酸鹽熔體 )。 6. 包裹體成分研究 （含成分分析的實(shí)驗(yàn)課） 6學(xué)時(shí) 偏光顯微鏡法； 冷凍法及鹽度與密度的測(cè)定； 氣相色譜法、液相離子色譜法； 激光拉曼探針?lè)ǎ? 電子探針、掃描電鏡法； 其它尖端技術(shù)。 教學(xué)大綱 7. 各種地質(zhì)環(huán)境中的流體 熔體包裹體 8學(xué)時(shí) 用包裹體研究礦床成因和礦物沉淀環(huán)境； 用包裹體研究闡明區(qū)域地質(zhì)或礦區(qū)地質(zhì)方面的問(wèn)題； 包裹體研究在普查勘探和尋找盲礦方面的應(yīng)用； 包裹體研究在地幔環(huán)境研究中的應(yīng)用； 包裹體研究在油氣田資源預(yù)測(cè)中的應(yīng)用 包裹體研究在古環(huán)境、古氣候研究方面的應(yīng)用。 some of the minerals from these sample groups have grown in the presence of an additional lowdensity vapor phase. New crystals in many sedimentary and some metamorphic rocks, and in almost all ore deposits, formed from an aqueous fluid containing various solutes. 引自 Edwin Roedder (1984) 1 礦物中的包裹體及研究歷史 (1) 礦物中的包裹體（續(xù)） After crystallization, the minerals of practically all terrestrial sedimentary, metamorphic, and igneous rocks have been fractured one or more times, and the fractures have healed in the presence of liquid or gaseous fluids. During these processes of crystal growth and fracture healing, small quantities of the surrounding fluid medium are monly trapped as fluid inclusions in the host crystal. If solid materials are also present in the fluids they may bee enclosed by the growing crystal as solid inclusions。 Dwight, 1820。 Ermakov and Dolgov, 1979, Thermobarogeochemistry, 271 pp。 they may even be of help in recognizing the precursors to explosive volcanism. (6) 油氣田地質(zhì) In the search for oil, fluid inclusions containing hydrocarbons and/or water have provided information on the tectonic and pressuretemperature evolution of petroleum basins prior to, during, and after hydrocarbon migration, and may provide information on the contentious issue of the mechanism of primary migration of petroleum. (7) 鹽類礦床 In some domal salt deposits, highpressure gas inclusions, presently of unknown origin, have prevented development of parts of the resource, because blowouts into mine openings from natural decrepitation of the inclusions in thousands of tons of such inclusionrich salt have resulted in fatalities. Recognition of such inclusions in core samples may thus prevent mining accidents. (8) 古氣候 In the study of the evolution of the atmosphere and paleoclimatology, gas inclusions in dated polar ice sh
