Dating ru bu 1
While there have been previous excavations of Late Pleistocene cave sites in the Yangzi Basin, the dating of these sites has been problematic.
First, the complex deposition of interdigitating lenses of ashes, clays, and sometimes fine gravel requires systematic dating based on a series of radiocarbon determinations and this has been lacking.
Numerous caves in the vast karstic landscape of the southern area of the Yangzi River basin of China are known to have been inhabited by hunter-gatherer groups during the Late Pleistocene and early Holocene.
The generally good preservation of the cave deposits and the presence of rich archaeological assemblages, including stone, bone, and shell tools, have led to a large number of excavations since the 1980s.
The cave is 12–15 m wide along its east-west axis and about 6–8 m wide from north to south.
The uppermost deposits were removed in historical time.
In addition to the radiocarbon dating reported here, we studied site formation processes using micromorphology and mineralogy.
The cave was first excavated in 19 by one of the authors (J.
Y.), who uncovered 2 clusters of potsherds indicating the presence of 2 vessels (Fig. A piece of charcoal closely associated with the potsherds was dated to 16,700–15,850 cal BP and organic residue from the ceramic to 17,750–16,900 cal BP (7, 16, 17, 25;) (Table 1).
Due to the crumbly state of the sherds, only one pot could be reconstructed.
Its form features a round rim 31 cm in diameter and a pointed base—a type known in the Chinese literature as a , with an excavation grid subdivided into squares (Fig. During the excavations in 2004–2005, we subdivided the large rectangular square T1 into 1 × 1 m squares and added, along the baulk between T1 and T3, four 1 × 1 m squares, T10-T13.
We then analyze 29 prescreened samples for radiocarbon contents.
