光释光测年对雷州新埠与旧洋古窑关键地层年代的约束及其意义
Chronological Constraints and Implications of OSL Dating for Key Stratigraphic Horizons at Xinbu and Jiuyang sites,Leizhou Kiln
摘要
Abstract
The Leizhou Kiln is one of the three major kiln sites in the Lingnan region,which are widely distributed across the Leizhou Peninsula.Over 100 kiln sites hosting 200 individual kilns have been discovered on the Leizhou Peninsula,constituting the largest cluster of civilian kilns along the coastline of China.However,chronological studies of the Leizhou Kiln are limited,with dating primarily relying on archaeological typology,and robust absolute chronological markers are lacking.The initiation and termination ages of the key historical kilns are unclear:the evolutionary trajectory of the kiln industry is thus unclear.Key stratigraphic samples were systematically collected based on the stratigraphic features of the Leizhou Kiln.Optically stimulated luminescence(OSL)dating was used to tentatively determine the initial firing age of the Xinbu Kiln and terminal firing age of the Jiuyang Kiln,yielding preliminary chronological data.Our findings show:1)Weathered debris from the fired bricks at the bottom of the Xinbu Kiln cultural layer produced strong luminescence with concentrated equivalent dose distributions,indicating the high reliability of the dating results.The ages obtained from the samples at the bottom of two independent cultural profiles were approximately 1.3±0.1 ka,different from the depositional ages of the topmost underlying primary sand layers(about 94.4 and 63.4 ka).This finding indicates that the kiln may have been in use since the mid-to-late Tang Dynasty.2)The OSL dating of two independent samples from the thin bottom sandy layer within the overlying colluvium of the Jiuyang Kiln cultural layer yielded ages approaching 0.2 ka.This indicated that the kiln may have been abandoned during the late Qing Dynasty,a finding corroborated by local oral historical records documenting the cessation of kiln operations during that period.3)This was a pioneering application of OSL dating for determining the time when the Xinbu Kiln was initiated and the Jiuyang Kiln was abandoned.This study refines the traditional view that Xinbu Kiln predominantly dated to the Song Dynasty and the Jiuyang Kiln primarily operated during the Song-Yuan period,revealing that the Leizhou Kiln provided long-term contributions to regional ceramic production in China.4)Applying the single-aliquot regenerative-dose protocol(SAR)method effectively overcomes the limitations of traditional typology in dating complex stratigraphy and kiln sites.This study provides a foundation for systematically integrating regional kiln chronology data and establishing an integrated chronological framework for the Leizhou Kiln.This temporal framework provides a crucial basis for describing the developmental trajectory of the Leizhou Kiln and its pivotal role in the Maritime Silk Road.关键词
