摘要

以前对中国广西淡水贝丘的年代估计一直存在争议，从约公元前 10,000 年到约公元前 5,000 年不等。由于可能存在淡水水库效应和潜在的骨质样本污染，对淡水贝壳和骨质样本进行放射性碳年代测定的准确性受到质疑。本研究介绍了对广西三个具有代表性的贝丘遗址的大型植物和淡水贝壳遗存进行的 18 个新的 AMS 测定结果。该项目表明，以往的测年方法和材料确实存在问题。本文介绍的初步研究成果表明，广西贝丘在全新世早期的堆积年代范围可能比以前认识到的要窄得多。

Chronological analysis of prehistoric freshwater shell mounds in the Yongjiang River Basin, Guangxi, China

Previous chronometric age estimations of freshwater shell mounds in Guangxi, China have been controversial, ranging from c. 10,000 to c. 5000 cal BP. The accuracy of the radiocarbon dating performed on freshwater shell and bone samples have been questioned due to the possible presence of a freshwater reservoir effect and potential bone sample contamination. This study presents new results of 18 new AMS dates obtained on macrobotanical and freshwater shell remains from three representative shell mound sites in Guangxi. The project demonstrates that problems do indeed exist with previous dating methods and materials. The preliminary research outcomes presented here indicate Guangxi shell mounds likely accumulated within a much narrower chronological range during the Early Holocene than previously recognised.

期刊介绍： Archaeological Research in Asia presents high quality scholarly research conducted in between the Bosporus and the Pacific on a broad range of archaeological subjects of importance to audiences across Asia and around the world. The journal covers the traditional components of archaeology: placing events and patterns in time and space; analysis of past lifeways; and explanations for cultural processes and change. To this end, the publication will highlight theoretical and methodological advances in studying the past, present new data, and detail patterns that reshape our understanding of it. Archaeological Research in Asia publishes work on the full temporal range of archaeological inquiry from the earliest human presence in Asia with a special emphasis on time periods under-represented in other venues. Journal contributions are of three kinds: articles, case reports and short communications. Full length articles should present synthetic treatments, novel analyses, or theoretical approaches to unresolved issues. Case reports present basic data on subjects that are of broad interest because they represent key sites, sequences, and subjects that figure prominently, or should figure prominently, in how scholars both inside and outside Asia understand the archaeology of cultural and biological change through time. Short communications present new findings (e.g., radiocarbon dates) that are important to the extent that they reaffirm or change the way scholars in Asia and around the world think about Asian cultural or biological history.
