摘要

INTRODUCTION Quaternary sediments contain the records related to the changes in paleoclimate and paleoenvironment. Grain size of the sediments is taken as the good indicator of the sedimentary environmental conditions related to the climate change (Xiao et al., 1995; McLaren and Bowles, 1985; Glasiter and Nelson, 1975). We report here the data of KT2 core samples to show the change of Quaternary paleoclimate in Tarim basin in Northwest China. BH KT2 core is located at the hinterland of Tarim basin (Fig. 1) and covers the whole Quaternary strata. The grain size was measured by Mastersizer-2000 Laser Grain Size Analyzer in the Laboratory of Institute of Hydrogeology and Environmental Geology, Chinese Academy of Geological Sciences.
