Sandy deposits of about 1-7 m in thickness tentatively named in this paper as the Noko sand and gravel Bed are observed at several localities of the Noko Island (Nokono-shima) in Hakata Bay of North Kyushu. The Noko sand and gravel Bed consists mainly of medium-and/or coarse-grained arkosic sand intercalating some granule-and pebble-sized gravels, and is megascopically indistinguishable from the Paleogene Nokonoshima Formation of Fukuoka Coal-field distributing in the southern area of the island. This bed is characterized by its mode of occurrence intimately accompanied by the overlying basalt and the basaltic pyroclastics which develop widely forming the plateau area of the island, and by its lithological feature of loose compaction scarsely containing of gravels of sanukitic andesite and lowranked coal matters. From the fact said above the geological age of the Noko sand and gravel Bed should be put between the age of volcanic activity represented by sanukitic rocks and that of plateau basalts. Consequently, this bed may be correlated to the Sarushi and Hachinokubo gravel beds overlain by the Matsura basalts in the Karatsu and Sasebo coal-fields of Northwest Kyushu. The tectonic movement of the Paleogene formations of the Fukuoka Coal-field including a tilting of the Nokonoshima Formation may have occurred before and continued after the deposition of the Noko sand and gravel Bed、judgingfrom the southward inclination of this bed and basalts.
