| Research Abstract |
It is very important for archaeologists that they recognize which the distribution of artifacts did not leave as it was before. We pointed out that it is possible to divide such disturbances into two groups on the basis of the time whether caused the process before laying in the soil or after. The latter group, moved from a position in situ, is reported from many sites throughout the country and some investigators understand how to move by actions. Raymond Wood et al. listed and examine nine processes of pedoturbation that cause soil mixing ; faunalturbation, floralturbation, cryoturbation, graviturbation, argilliturbation, aeroturbation, aquaturbation, crystalturbation and seismiturbation. We confirmed that the nine processes, observed by us in Japan, do not mutually exclusive and reflect the combined action of them. The former includes some problems of the taphonomy. We examined some sites in China and Japan which archaeologists excavated animal bones, and we stated that the distribution of animal bones did not cause from human action but animal action. We paid attention that the process, caused the disturbance of artifacts in soil and the breakage of ruins, does not always actin one direction, but operates more strongly as man disrupts environment. We carried out the survey in the field to make clear bigger energies which destroyed sites, like volcanic falls, mud flows, and so on, and reported a part of the result. We excavated the shell-mound on the slope (Osita-Shellmound, Aso-machi,Ibaragi Prefecture) and have conducted an investigation of garaviturbation to make move artifacts down.
