Late Paleocene Paleoclimate recorded in halite deposits in Subei basin ,East China

Salt deposits correspond to relatively extreme climate events. However, due to insufficient independent temperature proxies, there is a lack of paleotemperature records obtained from salt laminae deposition .The Paleocene evaporite sequence deposited in the Hongze Depression of Subei Basin provides an important terrestrial sediment record during this period. In this study we carry out a detailed fluid inclusion study on halite crystals in these rocks and present total of 488 homogenizaton data from eight samples. The results show temperatures ranging from 17.7°C to 52.3°C, and the mean T h value of 34.1°C is in good agreement with the previous studies of climatic proxies. Our study shows that fluid inclusions can be used as a robust tool to construct the ancient earth surface temperature.
