In this paper, the authors drilled a 42.85 m-long core (N06S2) in 2007, which was located in the south bank of Yangtze River at Shifuqiao in Qixia district of Nanjing City. Firstly, fine quartz grains (4~11μm)were extracted from bulk samples in dark room, and the quartz purity tests were conducted. The results show that purity can satisfy the experiment. All measurements were performed on an automated Daybreak 2200 TL/OSL system with blue (470±5 nm) light stimulation and U-340 luminescence detection filters. Secondly, the preheat plateau test and dose recovery test were performed on one sample using the SAR protocol. The results indicate that the fast component dominates the OSL signals. At last, samples from this drilling core were systematically dated by optically stimulated luminescence (OSL) dating method, and samples which contain organic matters were dated by AMS{14C}.The results show that the De values from the two methods accord with each other very well.
