桂林甑皮岩洞穴遗址钙华板^(14)C年代学研究

A Study of the ^(14)C Age of Tufa Layer in the Zengpiyan Cave Site of Guilin

甑皮岩遗址是新石器时代保存较完整的一个人类洞穴遗址,距今有8.0~12.0ka的历史。本文通过对洞穴遗址钙华板14C年代的测定,并对比了遗址内贝壳和木炭的14C年代。初步论证了钙华板14C年代的可靠性,并探讨甑皮岩古人类活动及穴居的最后年代为6.6kaBP。通过对钙华板14C年代研究为遗址洞穴地层的划分提供了新的年代依据。

Zengpiyan cave site is a well preserved integrated palaeo-anthropologic site with a history of 8.0 - 12.0 ka. In this paper, the authors have determined the ^14C ages of the tufa layer in the cave site and compared these ages with ^14C ages of shells and charcoal from ashes. Furthermore, the reliability of the ^14C age of the tufa layer has been demonstrated, and the last palaeo-human activity in the cave has been dated at 6.6 ka B P. The research on the tufa layer in the cave site has provided new age evidence for stratigraphic division in the cave site.
