摘要:Abstract(#br)Expeditions to Muztagata (in the eastern Pamirs) during the summer seasons of 2002 and 2003 collected precipitation samples and measured their oxygen isotopes. The δ 18 O in precipitation displays a wide range, varying from −17.40‰ to +1.33‰ in June-Septemb...

摘要:Abstract(#br)Rock magnetic and magnetostratigraphic investigations on a lacustrine sequence in the Nihewan Basin, northern China, which bears the Cenjiawan Paleolithic site, indicate that the dominant magnetic mineral and remanence carrier contained in the sediments is magnetite....

摘要:Abstract(#br)The dust transport and sediment characteristics are discussed based on analysis of microparticle size and size distribution in the Muztagata ice core at 6350 m a.s.l. The finer particles with diameter of 1-5 μm are the dominant fraction in number, while middle a...

摘要:Abstract(#br)Expeditions during the summers of 2002 and 2003 implemented continuous monitoring of near-surface (2 m height) atmospheric CO 2 and H 2 O concentrations at the 4500 m elevation on Muztagata. The resultant data sets reveal a slight decrease of CO 2 concentrations...

摘要:Abstract(#br)The 213 m ice core from the Puruogangri Ice Field on the Tibetan Plateau facilitates the study of the regional temperature changes with its δ 18 O record of the past 100 years. Here we combine information from this core with that from the Dasuopu ice core (from ...

摘要:Abstract(#br)Based on summer observations of stable isotope of precipitation at Muztagata, western China, during 2002-2003, this paper presents the relationship between δ 18 O in precipitation and air temperature, and discusses the effect of moisture transport on δ 18 O in p...
