摘要
ＰＩＸＥ（质子感应Ｘ射线分析）方法是目前国际上新的流体包裹体成分分析方法。在前人工作的基础上，尝试用ＰＩＸＥ方法分析了满洲里－新巴尔虎右旗斑岩系列多金属矿床石英流体包裹体的液相多元素化学组分，其结果反映了地质矿化规律。该方法对于多金属矿床石英流体包裹体成分研究非常有用。结合其他包裹体研究，提出甲乌拉与直干布拉根矿床流体组分和成矿物理化学条件均不同，初步认为不存在同一矿化中心；还提出了查干布拉根矿床西矿段深部可能存在乌奴格吐山式斑岩型Ｃｕ矿床，应引起注意。
The proton induced X-ray emission (PIXE) analysis is a new analytical method for fluidfrom fluid inclusions, and is attempted to analyze the multi-element composition of fluid fromfluid inclusions in quarts from porphyry series deposits in Manzhouli-Xin Barag Youqi area. Thecharacteristics of the analytical results are concordant with the geological ore forming law.Therefore, this method is useful for study on fluid inclusions and fluid property in porphyryseries deposits. It is concluded that the physicochemical conditions and the chemicalcompositions of fluid of both Chagan and Jiawula deposits are different, and nether of the twodeposits are derived from the same ore-forming center and there may be another porphyrydeposit near or in deep level of western Changan deposit.
