TheOshimaPeninsulainsouthwesternHokkaidoisregardedgeologicallyasthenorthern extensionofthe"GreenTuff"regionoftheInnerZoneoftheNortheastJapan(e.g.Katoetal.eds., 1990).ThepeninsulahasextensivedistributionsoftheNeogeneandQuaternarydepositswhich unconformablyoverliepre-Tertiarysedimentaryandigneousrocks.Thisregionhasbeenoneof stratigraphicalstandardsoftheNeogeneinHokkaidosincethestudybyNagaoandSasa(1933). NeogenetoPleistocenemarinesedimentsinthisregionaregenerallyclassifiedintothefollowing ascending-orderedformations,Kunnui,Yakumo,Kuromatsunai,andSetana(NagaoandSasa, 1933).Theseformationsarewellexposedinmiddletonorthernpartsofthepeninsula.Such stratigraphyfirstproposedbyNagaoandSasa(1933)hasbeenaccepted,butrecent biostratigraphicaldatarevealthattheSetanaFormationshouldbeofPleistoceneage(e.g.Nojoet 1)DepartmentofScienceEducation. ,IwamizawaCollege,HokkaidoUniversityofEducation,.
