| Abstract: | The speleothems
collectd from Hulu Cave, Nanjing have been dated with the thermal ionization mass
spectrometry technique (TIMS), a recently developed dating method for cave carbonates. The
ages of the speleothems could be used to estimate the ages of the Nanjing Ape Man. The
TIMS age of the flowstone onlapped the culture relic layer containing No.I cranium fossil
is about 529 32-27 kaBP, which locates the upper limit age of the
Nanjing Ape Man. The age of the stalagmite overlapped on this flowstone layer consequently
suggest this upper limit. The dated age of the flowstone underlying the fossil layer
indicates that the Nanjing Ape Man was no older than 723 ka BP.Therefore, the ages of the
speleothems in this paper provide a firm evidence for the existing period of the Nanjing
Ape Man which is much older than those suggested previously. |
