Abstract

The author deals with the stratigraphy and lithofacies changes of the Sasebo group in the Sasebo coal field on the basis of the data obtained in drilling with additional ones from the surface and underground observations. The lithofacies changes are on the whole rather small except in the Fukui and Kasé formations which are the upper portion of this group, and generally muddy facies increase toward the west while the sandy facies increase toward the east. Each formation shows a tendency of decreasing in thickness toward the west. The variation of the thickness is considered to have a relation with the sediments. The relation between the Nojima and Sasebo groups is regarded as an unconformity, and that between the Kasé, the uppermost formation of the Sasebo group, and the underlying Fukui formation as a disconformity.
