黑龙江密山黑土剖面记录的全新世以来的气候变化
Climate change since Holocene recorded in Mishan black soil profile of Heilongjiang Province
摘要
Abstract
The paper studies the geochronology,magnetic susceptibility,particle size and element geochemistry of black soil profile(0-1.42 m)in Mishan City.The results show that the sediments of black soil profile are mainly silt,accounting for about 70%,and the deposition rate of black soil is 9.62 cm/ka according to the age curve.The element geochemical data reveals that the major element combination characteristics of Mishan black soil profile are similar to those of other typical eolian deposits,and the change trend of UCC-normalized curves is basically the same,indicating the parent material of Mishan black soil may be of aeolian origin.The multi-index comprehensive analysis shows that the climate change of Mishan black soil profile since Holocene has experienced three stages,i.e.temperature rising in the Early Holocene,warm and humid in the Middle Holocene and cooling down in the Late Holocene.关键词
