柴达木盆地应用自然伽玛反演辨认的末次冰期以来的Heinrich事件

采用柴达木盆地达参１井自然伽玛曲线进行古气候反演，得出了末次冰期以来６个短尺度的气候变化事件，与北大西洋Ｈｅｉｎｒｉｃｈ事件（Ｈ１－Ｈ６）及格陵兰冰心和黄土中的短尺度气候事件均能较好对应，一方面表明内陆湖盆能记录气候长尺度和较短尺度气候变化事件，是反映古气候变化良好的信息载体之一；另一方面也证明了自然伽玛曲线能气候长尺度及短尺度的气候变化事件，表胆自然伽玛曲线能较真实反映古气候变化情况，是良好的古

Heinrich Events Identified by Gamma Logging Curve During the Last Glacial Period in Qaidam Basin

Using gamma logging curve of Dacan 1 core to inverse paleoclimate changes in Caidam Basin,Six of short timescales climate change events during the last glacial period were obtained,which can be matched well with Heinrich events(H1 H6)in North Atlantic Ocean and the short timescales climate change events of Greenland ice core and Chinese Loess.It shows that paleolake of inland is one of the well information carriers of paleoclimate change,for both of long and short timescales climate changes can be recorded in it:it also indicates that gamma logging curve can identified both of long and short timescales climate changes,it can be regarded as one of the favorable climate proxy.
