Based on U/Th dates and 205 oxygen isotopic dates a record of the Asian Summer Monsoon (ASM) on millennial time scales was established during the Antepenultimate Glacial MIS8-MIS9 from stalagmite LM-1 in Laomu Cave from southeast of the Loess Plateau, the west of Henan Province, China. The minimum δ¹⁸O value of stalagmite LM-1 is-11.38‰, the maximum value is -6.99‰ and the vibration amplitude reach -4.37‰, mean -9.07‰, and showed this area was strongly affected by the Asian Monsoon system during the Antepenultimate Glacial. The δ¹⁸O record of stalagmite LM-1 is similar to that of the stalagmite LZ-15 of Linzhu Cave in Shennongjia, Hubei Province, China. So we can infer from that the content of CO₂, CH₄ and NO₂ changing may amplify the climate fluctuation caused by the orbit driven.
