A statistics in world range indicates that the Sr/Eu ratios in the peraluminous granites show similar variation trend to those in pegmatitic apatites. This paper suggests that the high Sr/Eu ratio (＞300) in apatites or peraluminous granites is due to the strong partition of Eu〓 into the aqueous fluid, and this ratio can be used as an excellent geochemical indicator of fluid exsolution from magmatic melts.

对世界范围内的过铝质花岗岩统计表明，过铝质岩浆岩的全岩样品中的Sr/Eu也呈现二歧变化，由此本文提出Sr/Eu比值是指示过铝质岩浆体系中岩浆流体相出溶的有效地球化学参数，大于300的Sr/Eu比值是Eu〓强烈分配进入流体相的地球化学标志。

They are most abundant in quartz of pegmatitic leucosomes and granitic rocks, and represent the fluid appearing in their cooling stage. The DL(H2O) of such fluid is 0.93～0.96g/cm3 corresponding to P≈0.6GPa which is compatible with condition when the rapid decompression in this region was ended. 3 CO2-H2O two or three phases inclusions. They are the most widespread, and more frequently in clusters and in intragranular tails in quartz. The relative content of CO2+CH4 and H2O is considerably variable. They are also characterized with lower density (0.6～0.8g/cm3) and low pressure about 0.3～0.4GPa, and may be originated by mixture of carbonic liquid from breaking of most inclusions of peak stage and aqueous liquid of magmatic source. After entrapment, the further decrease of temperature to lower than 330℃ made such fluid separated to two or three phases.

主要集中于伟晶质脉体和花岗岩中，是这期岩浆冷凝过程析出的流体相当时就被封闭所成，密度为0.93～0.96g/cm3，相应压力约0.6GPa，这与峰期后迅速减压过程结束时的条件相符。3CO2-H2O两相和多相包体，分布最广，成簇状和拖尾状包体群，碳质和H2O相对含量很不均匀，整体密度相对最低，一般为0.6～0.8g/cm3，相应压力为0.3～0.4GPa，它们可能是大幅度减压过程中第一类包体大量爆裂析出的碳质流体与第二类H2O溶液流体在各处以不同比例混溶所成，它们被封闭后在降温至330℃以下时分裂成两相或三相包体。

It is found that there is a co-relationship between the boron isotope and chemical composition of magmatic tourmaline: the δ〓B value increases with increasing Al and Li in Y-site of tourmalines. The low δ〓B values (-41. 1～-39. 01‰) in Altay No. 3 pegmatite, which is one of the lowest values found by now, imply that non-marine evaporites might exist in magma source, or the pegmatitic magma had been assimilated by them during its intrusion and emplacement.

阿尔泰3号伟晶岩最初形成的结构带中电气石的B同位素组成是目前所发现的最低值之一(-41.11～-39.01‰)，指示形成伟晶岩脉的初始岩浆可能由含非海相蒸发岩的泥质岩经变质深熔作用形成，或是伟晶岩岩浆在上侵定位过程中同化了含非海相蒸发岩地层的结果。
