- W2367989872 abstract "The Qitianling granite complex associated with the Furong tin deposit is composed primarily of hornblende-biotite granite and biotite granite,with the latter being intruded later than the former.Electron microprobe analysis indicates that biotite from hornblende-biotite granite is annite and that biotite from biotite granite is siderophyllite.The biotite from horublende-biotite granite has higher MgO and TiO_2contents but lower Al_2O_3contents than the biotite from biotite granite.The crystallization temperatures and oxygen fugacities(logf_(O_2))of the biotite in hornblende-biotite granite are 680 to 740℃and-16.00 to-15.31 respectively,and those of the biotite in biotite granite are 530 to 650℃and-19.20 to-17.5 respectively.The temperatures and oxygen fugacities decrease gradually from hornblende-biotite granite to biotite granite.Study of the nature of the hydrothermal fluids coexisting with the Qitianling granite indicates that the values of log(f_(H_2O)/f_(HF))~(fluid),log(f_(H_2O)/f_(HCl))~(fluid)and log(f_(HF)/f_(HCl))~(fluid)of the hydrothermal fluids coexisting with hornblende-biotite granite are 4.22 to 4.39,2.78 to 3.24 and-1.82～to 1.73 respectively,and those of the hydrothermal fluids coexisting with hornblende-biotite granite are 3.27 to 3.53,2.85 to 3.22 and-0.75 to-0.22 respectively.Therefore the fluids coexisting with the two types of granite are different obviously in nature,and there is a positive correlation between the contents of Cl and Sn in hydrothermal fluids and the crystallization differentiation index of magmas.From hornblende-biotite granite to biotite granite, hydrothermal fluids separated during magmatic crystallization became Cl-and Sn-rich with magmatic evolution,and the ore-forming fluids should be mainly derived from the magmatic hydrothermal fluids separated during the crystallization of biotite granitic magma." @default.
