Here we present results of 230Th dating, stable isotope and lamina thickness data from two stalagmites (CS01C and SHD1311) from Shihua Cave (latitude 39´47°N, longitude 115´56°E; altitude 251 m a.s.l. at the entrance), northern China, during 11.32 to 10 ka BP. CS01C developed with clear annual lamina. The age model of CS01C is based on lamina counting. The age model of SHD1311 is established using the COPRA algorithm. The variability of stalagmite δ18O records is interpreted as a proxy of regional summer monsoon precipitation and/or EASM intensity. Stalagmite δ18O records show two weak summer monsoon events at 10.9 and 10.3 ka. The 10.9-ka event occurred from 10.93–10.79 ka BP for ~140 yr and features a “W”-shaped structure. The 10.3-ka event, also known as the ice-rafted debris event 7 in the North Atlantic, lasted ~260 yr with an asymmetric double-plunging structure.
