【Abstract】 In the study of fluid inclusions, the authors have found that there exist pure liquid inclusions not only in sedimentary minerals, but also in the minerals from sedimentary-reformed and sedimentary-lightly metamorphic ore depo sits and hydrothermal ore deposits related to magmas. Such kind of liquid inclusions can be formed not only in cold solutions at 50℃, but also in hydrothermal solutions. Studies of fluid inclusions in natural and synthetic minerals permit one to divide the pure liquid inclusions into two broad types; formed under low temperature conditions and under specific geological conditions. Their features and modes of occurrence are quite different from those of gaseous inclusions. Experiments showed that there would appear gaseous and liquid phases when the fluid became a non-homogeneous system by means of freezing. Then, by heating till the two phases homogenized,the homogenization temperature could be accurately measured. This work-is of some significance in perfecting the basic theory on fluid inclusions and studying the minerogenetic theory on sedimentary and sedimentary-reformed ore deposits.更多还原
