The Research on the Homogenous Temperatures of Inclusions in Halite from the Isothermal Evaporation of Brine and Natural Halite from Lop Nor Playa, Xinjiang, China
Halite has crystallized at the 30℃ and 52℃ isothermal evaporations in lab from brine of Lop Nor salty lake, Xinjiang, China. And the plenty of liquid-phase inclusions occur in the halites. The homogenous temperatures of liquid-phase inclusions in halite is measured. The results show that only few temperature data of liquid-phase inclusions are close to 30℃ and 52℃ temperatures of brine, but most of the temperatures are by 20 - 90 ℃ higher than the fixed temperatures, a few are by 6 - 30℃ lower than those. In addition, the homogenous temperatures of natural halite from salty lake of Lop Nor also show the similar case, i. e. , most of them are obviously away from the possible temperature of the halite-crystallizing brine. These materials show that they are influenced by a few factors. Therefore, the homogenous temperature of liquid-phase inclusions in halite must be carefully applied in determining the temperatures of paleo-lake water or medium; only through the synthetic analysis, are the reliable information obtained.
