Fluid inclusions in various quartz minerals with sizes of less than 30 μm were analyzed by ion microanalyser by special techniques. The fluid inclusions were frozen in the specimen using the cooling system connected to the specimen stage. Electrons charged up on the specimen surface were neutralized by electron spray technique. The quantitative analysis seems possible by measuring the relative ion intensity to the synthetic specimens prepared by enclosing aqueous solutions containing various salts into fused silica capsules. Analytical results of the fluid inclusions in various quartz minerals indicate the characteristic features of their components and relative ion intensities. Even in the same deposit, the composition of the fluid inclusions varies with the mineralizing period. Especially, noticeable variations in magnesium and aluminum contents were observed. Fluid inclusions in quartz contained heavy metal ions such as manganese, iron, copper and zinc. These facts support that the fluid inclusions in quartz will allow the estimation of the mineralizing conditions of ore deposits
