A rich stone tool assemblage is described of the Sangoan-type from a potentially semi-primary site, in association with a well-preserved fauna, and in paleo-environmental context. The site appears to be late Middle Pleistocene and contains a high proportion of small to medium-sized mammals (e.g. rodents, monkeys) deposited in low energy conditions. The environment is suggestive of a fringing woodland or riverine forest contained in a subarid climate. 相似文献

The temporal change in the number of oxygen vacancies in quartz was investigated by ob-serving the E1’ center in the atmospheric depositions collected at two cities in Japan in the recent past. The depositions collected at Fukuoka in March show the ESR intensities being correlated with the sum of the number of the days, in the month, on which Kosa was observed while no such correlation was found in the deposition those collected at Akita but a trend of decrease with time. The present results suggest that the number of oxygen vacancies in quartz might be useful to estimate quantitatively the contribution of the dust originated from China to the atmospheric deposition in Japan. 相似文献
