The method is mainly applied for porcelain datillg. To test the method, some simulated paleodoses of the imitations of ancient porcelain were used. The measured results are in good agreement with the simulated values of the paleodoses, and the average ratios of the two values by using the two ways are 1.05 and 0.99 with standard deviations (±lσ) of 19% and 15% respectively. Such errors can be accepted in porcelain dating.展开更多

It is a good example for the study of Shanghai history in the Wusongjiang River irrigation, the ancient shipping and the town development. Based on the data of microfossil Pediastrum, Zygnema, Concentricystes, diatom, foraminifera and ostracods from the sediment section of the relics, the paleostream change after the construction of the sluice was guessed. The paleostream was influenced by the sea water due to the connection with the sea in the earlier stage. The upstream of the sea water was enhanced in the middle stage that was indicated by the increase of marine diatoms and foraminifera. The decrease of marine diatoms and foraminifera in abundance reflected that the connection of the paleostream with the sea was reduced, and the sea influence was decreased gradually in the later stage.展开更多

The landscape is plain with an altitude of 2-3 m. As part of the project to investigate the formation process of the ancient civilizations aroundthe Lake Tai 太湖 area, we conducted excavation and coring at this site in 1999-2000. The remains of the Liangzhu Culture 良渚 are primarily from burials. We also found a new kind of late Neolithic remains, which we temporarily name them as the “Guangfulin Remain.”展开更多

It was discovered in 1966 when a local water supply facility was constructed. In 1988 and 1990, we excavated 968 sq m at this site and found two Song Dynasty tombs, one Tang Dynasty tomb and 23 burials of the Liangzhu 良渚 Culture (Fig. 1). This paper reports the discovery of the burials of the Liangzhu Culture.展开更多
