The unstratfied orebody occurs unconformably in the main preliminary study of oreforming fluids shows that fluid inclusions is quartz form altered stockwork rocks that represent the pipe facies have a wide range of temperature and intense fluid activities are characteristics of the pipe facies of the exhalative inclusions in carbonates near the unstratified ore badies hosted in thickbedded marble which represents ventproxinmal facies are large in size and have moderate to high represent unerupted subseafloor fluid activity. Fluids in altered stockwork rocks and carbonates have similar H2ONaClCO2 system and higher temperature,both belonging to the sedimentaryexhalative fluids migrate from the pipe facies to the unstratified ore homogenization temperature and freezing temperature of sluid inclusions from stratifid ore bodies are similar with unstatified ore bodis,but lack the inclusions of great gas/liquid ratio and containing daughter minrals and CO2 ponent in fluid and the homogenization temperature is slightly lower .That is to say their fluid is deposit is evidenced an sedimentary exhalative on system by isotope geochemical study and fluid in feeders were deeply of deeplysourced gaseous ponnts such as CO2 and mixing of deelysourced fluids with seawater caused precipitation of oreforming materials. A study of Pb isotope geochemistry suggests that the first array, consisting of most of the ore samples, represents a twoponent mixing line in which the less radiogenic ponent can be identified as orogenic lead reservoir probably ing from Tianjianshan Group through the exhalation brine. The radiogenic endmember can be identified as upper crust lead reservoir probably derived from 、流體包裹體研究、成礦規(guī)律等青海錫鐵山鉛鋅礦礦床成因研究 St udy on genesi of Xi tieshan leadzinc deposi t, in Qinghai Pr ovince摘 要 錫鐵山鉛鋅礦床產(chǎn)于青海省柴達(dá)木盆地北緣早古生代烈焰的中基性火山 沉積巖系中，發(fā)育一套完整的噴流沉積系統(tǒng)，包括管道相，近噴口相以及噴流嗓鈍紡角哀霉淫裴孺喻怪測(cè)叼馱暮封褐暇釘局鼎挺湃支扭按騰雞痔昧伸渝與準(zhǔn)兜胖窘尾選躲余巴狐綜轟解牛章丁風(fēng)賃泳氖亞耀裹緘滿(mǎn)先脈辛彼翌?yuàn)W Keywords ： Geologicalfeatures。管道相成礦流體以深源為主，深源流體的CO2等氣相組分溢出及深源流體與海水的混合作用導(dǎo)致了成礦物質(zhì)沉淀。代表近噴口相的產(chǎn)于厚層狀大理巖中的非層 狀鉛鋅礦體旁側(cè)的碳酸鹽中包裹體個(gè)體大，溫度高，亦有明顯的形成于未噴出海底的中 高溫?zé)嵋夯顒?dòng)特征。 青
