 note = {Core boring was performed near the Ikirike early-Jyomon-period site on a small coastal plain facing a closed inner bay, Oomura Bay. The core is 4.73m long, and composed of Holocene marine sandy-to-silty sediments with molluscan and diatom fossil assemblages, which indicate the sediments were formed beneath shallow sea like an inner bay. The 14C dating determines the age, 7620±145yr. B. P., from the peaty silt at the base, -5.9 m.a.s.l., in the core. The diatom flora for this part consists of brackish-water species such as Navicula yarrensis. The altitude of the dated silty sediment shows the earliest sea-level which the Holocene transgression reached in the boring site. According to previous reports, the sea-level is -6m in ca. 7,600 yr. B. P., -1m in ca. 5,900y. B. P., and -0.5 to-0.2m in ca. 5,500 to 5,300 y. B. P. at the Ikiriki site., 長崎大学教育学部自然科学研究報告. vol.53, p.27-40; 1995},
