摘要
In this study, the authors measured a series of homogenization temperature of fluid inclusions in both cumulate and chevron halite crystals grown in the laboratory at a temperature of 40 ℃ (air temperature) in a thermostatic air drying oven in 20 cm deep brine in order to reconstruct the paleotemperature using homogenization temperatures directly. The homogenization temperatures range from 10.6 ℃ to 39.9 ℃. The results show that only the maximum homogenization temperature of fluid inclusions (Th max) matches brine temperatures. Both cumulate halite and chevron halite have a similar Th max, both types of halite can be used in paleotemperature reconstruction in shallow water.
