When using quartz OSL to date loess samples from the Chinese Loess Plateau, it has been reported that agreement between ages and independent is limited younger than ∼70 ka with a corresponding De of ∼230 Gy, sample an expected age 780 was dated 107 ka, 403 Gy. The growth curves these do not saturate at doses 700 linear part observed for higher 200 However, maximum measured ∼100 imply determined this curve could be problematic, or signal as stable previously thought barrier ka. In current...
Abstract The development of the Gurbantunggut Desert is mainly controlled by Westerly wind, and at present has little influence from Indian Southeast Asian monsoons. A combined study using optically stimulated luminescence (OSL) dating, ground‐penetrating radar (GPR) surveys climatic proxies analysis was carried out in southern part desert. chronology extends back to 18 ka constructed based on 16 OSL ages boreholes linear dune body inter‐dune area. suggests that sand deposition last...
Chang'an (now Xi'an) was the capital of Western Han Dynasty and starting point Silk Road. In light importance as centre politics, economy cultural interaction, overarching question proposed in this paper is focused on its role mirror production distribution network during period. On basis chemical lead isotopic analyses 34 mirrors, discusses potential existence a Chang'an. Meanwhile, comparative study with mirrors uncovered from south‐western frontier Central Asian North‐East countries...
The Dingcun locality 54:100 site was first excavated in 1950 s and has since yielded abundant stone artefacts the famous 'Dingcun human' fossils, including three teeth a parietal fragment. been regarded as potential evidence of early emergence development 'modern' anatomic characters, making them key to understanding origin evolution our species. However, there considerable debate regarding chronology site. Here we establish new for site, based on optical dating fossil-bearing sediments...
Abstract A rapidly increasing number of bronze mirrors dated to the Chinese Han dynasty (202 BC – AD 220), known for their unique decorative patterns and highly developed alloying techniques, have been widely discovered in both China beyond, providing fresh materials scientific data revisit geological provenance, production circulation network along ancient Silk Road. In this paper, 47 unearthed southeastern provinces China, including Zhejiang, Anhui Fujian provinces, characterized by...
This study utilizes OSL-SAR, TL-SAR, and TL-MAAD methods to date heated quartz extracted from burnt clay pottery samples the Lingjiatan archaeological site, China. The OSL components of were determined by deconvoluting CW-OSL curve, Fast Ratio value was used distinguish whether initial signal dominated fast component. results show two types characteristics in signals: Type I is component (Fast values > 10), while II medium slow < 10). bright signals, a preheat plateau appears...
X‐ray fluorescence (XRF), diffraction (XRD) and Raman spectroscopy were employed to analyse the chemical compositions phase structures of nine pieces jade artefacts unearthed from Sujiacun, a Longshan Culture (2400–2000 bce ) site in coastal Shandong, eastern China. The results analyses indicated these samples primarily made multiple raw mineral materials, including antigorite, actinolite, clinochlore, turquoise muscovite. No nephrite was recovered Sujiacun site. This is strikingly different...
As one of the key, long-term occupied sites in Southern Levant, Jericho was most important early Neolithic centres to witness social and economic changes associated with domestication plants animals. This study applies strontium (87Sr/86Sr), oxygen (δ18O) carbon (δ13C) isotope analyses enamel 52 human teeth from Pre-Pottery (PPN) layers directly diet mobility investigate degree consolidation flexibility organization society PPN period. The results indicate only two non-local individuals out...
ABSTRACT Bangladesh is one of the most densely populated countries in world. There are 57 trans‐frontier rivers country, widest being Brahmaputra River. The river's channels have frequently changed course, but relationship between such river migrations and human settlement patterns has remained unstudied. In this paper, optically stimulated luminescence radiocarbon dating techniques were applied to sedimentary organic materials oldest urban center (Wari‐Bateshwar) Bangladesh. results showed...
