青藏高原西南部仲巴地区细石器人类活动的时代探讨
Age of Microlith human activities in Zhongba area, southwestern margin of Qinghai-Tibet Plateau
摘要
Abstract
Three Microlith relic sites have been found in Zhongba area,southwestern margin of Qinghai-Tibet Plateau.Anaeolian deposit (ZZ)near Microlith relid sites was chosen,accelerator mass spectrometry (AMS) 14 C analysis and optically stimulated luminescence (OSL)of ZZ were used to determine ages,grain size and geochemical parameters were analysed.Relationship between Holocene environment and human activities was reconstructed,the time of Microlith human activities in Zhangba area was determined.It was found that from 8.9 ka BP to 7.3 ka BP,climate was humid,aeolian activity was weak with strong pedogenesis,with relative abundance of natural resources which were good for hunting of Micorlith human.From 7.3 ka BP to 3.8 ka BP,climate was dry,aeolian activity was strong,which was not conducive to human activities.It is therefore concluded that the formation time of Zhongba Microlith relics might be from 8.9-7.3 ka BP.关键词
