抄録: The earthenware ranging from an early stage to the last in the Jomon period had been excavated from Bibi remains in Chitose City,Hokkaido.The mineralogical compositions of the six potsherd samples representative of each stage were examined by using polarizing microscope and x-ray powder diffraction technique.Based on the results,we inferred that the all sample potsherds had been made of the same clay. The mineralogical composition of the fired paste is typically as follows.Quartz,plagioclase(andesine),hornblende,biotite and volcanic glass are scattered in the matrix whose color is reddish black due to opaque iron oxide.A small amount of tridymite is also detectable on the x-ray powder diffraction patterns. One kind of clay originating in Tarumae volcanic ash was appropriately inferred to be raw material,based on the compositional and stratigraphical judgement.The clay was fired under the various temperature-control conditions,with the intention of examining the correspondence to the fired paste of sample potsherds.We confirmed the unsatisfactory correspondence,however. The compactness of a fired paste,gained through firing and sintering,increases the resistivity against weathering. We interpreted the fact as a cause of the unsatisfactory correspondence.But it wasn't that the situation was thoroughly explained by the above interpretation. Finally,We inferred that the paste of sample potsherds had been prepared by compounding the clay mentioned above and either followlng raw material.0ne is another kind of clay which hasn' t its origin in any volcanic ash,and the other is a temper such as a small amount of river sand rich in quartz.We also inferred that the temperature of firing the sample potsherds had been about,probably not beyond,8000C.
