Abstract	On the bottom sediments collected on the continental shelf, off the Shimane Peninsula, heavy mineral analysis was carried out, and distributional patterns of heavy minerals and their provenances were ...discussed in this paper. The heavy mineral concentrates (2-3Φ, and 3-4Φ, size-fractions) in the continental shelf sediments are composed mainly of green hornblende, clinopyroxene, hypersthene, brown hornblende, oxyhornblende and olivine, and subordinately of zircon, tourmaline and rutile. The similarity of these mineral assemblages among the studied samples were statistically examined by the cluster analysis method. Thus, four groups were recongized for 2-3Φ, and 3-4Φ, size-fractions, respectively. On the basis of these results of the cluster analysis, four heavy mineral provinces (A, B, C and D) are proposed, each of which shows the following mineral suite and distribution area (Fig. 24) : A :cl inopyroxene + olivine ; off the eastern Shimane Peninsul B: cl inopyroxene + olivine ;ar ound the Oki Island C: brown hornblende + oxyhornblende + hypersthene + zircon ;shallow sea east of the Shimane Peninsula D: green hornblende + clinopyroxene + olivine + zircon ;Oki Strait and bottom areas deeper than 150m Heavy minerals from these mineral provinces are in general clearly traceable to their source rocks exposed on nearby land areas.show more
