Ware-types can be from very widespread kiln-sites in either north or south China, but the two can nearly always be distinguished, and influences across this divide may affect shape and decoration, but will be based on very different clay bodies, with fundamental effects. Southern materials have high silica, low alumina and high potassium oxide, the reverse of northern materials in each case.
The northern materials are often very suitable for stoneware, while in the south there are also areas highly suitable for porcelain.
Multivariate analysis was performed on percentages of 46 species of unstained deep-sea benthic foraminifera from 131 core-top to near-core-top samples (322–5013 m) from across the Indian Ocean.
Faunal data are combined with GEOSECS geochemical data to investigate any relationship between benthic foraminifera (assemblages and species) and deep-sea properties.
The foraminiferal census data combined with geochemical data has enabled the division of the Indian Ocean into two faunal provinces.Claims have been made for the late Eastern Han dynasty (100–200 AD), the Three Kingdoms period (220–280 AD), the Six Dynasties period (220–589 AD), and the Tang dynasty (618–906 AD).Whatever the definition used, there is no question that the Chinese were the first to make it.The earliest Chinese pottery was earthenware, which continued in production for utilitarian uses throughout Chinese history, but was increasingly less used for fine wares.Stoneware, fired at higher temperatures, and naturally impervious to water, was developed very early and continued to be used for fine pottery in many areas at most periods; the tea bowls in Jian ware and Jizhou ware made during the Song dynasty are examples.
Les résultats des analyses des outils lithiques découverts aux gisements dans une partie de cette région, le Bassin de la Phuthiatsana ea Thaba Bosiu (PTB) du Lesotho occidentale, sont présentées pour examiner si des changements aux stratégies de subsistance et de l'occupation des sites se réfletent à l'organisation des technologies lithiques.
