Abstract:
A lake shallow well section with the depth of 250 cm in Bilutu of central Inner Mongolia was studied. According to the six dating data of optically stimulated luminescence, the chronology for the lake sediment since the late stage of Late Pleistocene(56.8 ka)was established, and geochemical features including sedimentary characteristic, ratio of the contents(mass fractions)of Rb and Sr, content of oxide and the ratio of them were used to reconstruct the paleoenvironmental and climatic changes since the late stage of Late Pleistocene in Bilutu. The results showed that the climatic and environmental changes since the late stage of Late Pleistocene in Bilutu were divided into five stages. The first stage was from 56.8 ka to 49.5 ka, the organic matter in sedimentary deposit was rich, the chemical weathering was strong, the climate was mainly warm-dry-slightly damp; the second stage was from 49.5 ka to 41.3 ka, chemical weathering was weak, hydrothermal condition was poor, the climate was cold-dry-slightly damp; the third stage was from 41.3 ka to 20.8 ka, the climate became warm, the chemical weathering was strongest, the temperature raise and precipitation was high, the stage was interstade of last glaciation with little fluctuation of cold-wet and warm-dry; the fourth stage was from 20.8 ka to 8.2 ka, all the geochemical indicators changed significantly, sand wedge developed, climate deteriorated, the stage was continually dry-cold, and there was Last Glacial Maximum(LGM); the fifth stage was from 8.2 ka to now, the climate was mainly warm-dry, the climate became to cold-dry in the late of the stage significantly.
