摘　　要：根据非海相与海相,特别是共同的海相和非海相软体动物化石的对比,并结合放射性同位素测年,中国东北黑龙江东部和辽宁西部,韩国东南部庆尚盆地,日本西南部内带岐阜县北部牧户/庄川地区和外带四国德岛和物部地区早白垩世地层得到了对比,产自这些地层的非海相软体动物的时代也因此受到了约束。著名的中国东北含煤地层龙爪沟和鸡西群,盛产热河生物群/动物群的热河群的时代均为欧特里沃期/巴列姆期阿普特期,它们的上覆地层桦山群和孙家湾组为阿尔必期。韩国西南部新洞群和除金洞组以外的河阳群为阿普特期阿尔必期,不整合于新洞群之下的卯谷组主要为欧特里沃期。日本西南部内带的牧户/庄川地区的手取群和外带德岛和物部地区的物部川群均为欧特里沃期阿尔必期。Cuniopsis kihongi,Nakamuranaia leei,Koreanaia cheongi和Trigonioides(Wakinoa)tetoriensis的时代为欧特里沃期早巴列姆期。Viviparus onogoensis,Unio ogamigoensis,Myrene(Mesocorbicular)tetoriensis及Tetoria(Tetoria)yokoyami为欧特里沃期阿普特期。Arguniella cf.quadrata,A.cf.ventricosa,Sphaerium(Sphaerium)anderssoni,Probaicalia vitimensis和Pr.gerassimovi为欧特里沃期/巴列姆期阿普特期。Nakamuranaia chingshanensis,Plicatounio(Plicatounio)multiplicatus,Sphaerium(Sphaerium)coreanicum和Micromelania?katoensis为阿普特期阿尔必期。Nippononaia sinensis,Nip.tetoriensis,Nip.ryosekiana和Trigo-nioides(Wakinoa)wakinoensis是阿普特期的标志。Trigonioides(Trigonioides)quadratus,T.(T.)heilongjiangensis,Plicatounio(Plicatounio)naktongensis,Unio longus与Sphaerium(Sphaerium)chintaoense为晚阿普特期阿尔必期或阿尔必期的标志化石。我国东北、韩国东南和日本西南部非海相,特别是淡水软体动物接近的相似性表明这三地区在早白垩世时相连,并处于同一水系。但是,在欧特里沃期阿尔必期期间,这一陆块的东部,即频临古太平洋的On the basis of non-marine and marine correlation, particularly between the common marine and non-marine molluscan fossils, together with radiometric dating, the Early Cretaceous strata of eastern Heilongjiang and western Liaoning in NE China, the Gyeongsang Basin of SE Korea and the Makito/Shokawa area of northern Gifu in the Inner Zone, and the Tokushima and Monobe areas of Shikoku in the Outer Zone of SW Japan are correlated, and, as a result, the ages of the non-marine molluscs yielded from these strata are constrained. The well-known coal-bearing Longzhaogou and Jixi groups and the Jehol Biota/Fauna-bearing Jehol Group of NE China are all Hauterivian/Barre- mian-Aptian in age, and the overlying Huashan Group and Suinjiawan Formation are Albian. The Sindong Group and the Hayang Group, with the exception of the Jindong Formation, in SE Korea is Aptian-Albian, and the Myogog Formation unconformably underlying the Sindong Group is mainly Hauterivian. The Tetori Group in the Makito/Shokawa area and the Monobegawa Group in the Tokushima and Monobe areas of SW Japan are both Hauterivian-Abian. Cuniopsis kihongi, Nakamuranaia leei, Koreanaia cheongi and Trigonioides （Wakinoa） tetoriensis are Hauterivian-early Barremian in age. Viviparus onogoensis, Unio ogamigoensis, Myrene （Mesocorbicular） tetoriensis and Tetoria （Tetoria） yokoyami range from Hauterivian to Aptian. Arguniella cf. quadrata, A. cf. ventricosa, Sphaerium （Sphaerium） anders- soni, Probaicalia vitimensis and Pr. gerassimovi range from Hauterivian/Barremian to Aptian. Nakamuranaia ching- shanensis, Plicatounio （Plicatounio） multiplicatus, Sphaerium （Sphaerium） coreanicum and Micromelania？ katoensis are Aptian-Albian. Nippononaia sinensis, Nip. tetoriensis, Nip. ryosekiana and Trigonioides （Wakinoa） wakinoensis are good indicators of the Aptian. Trigonioides （Trigonioides） quadratus, T. （1.） heilongjiangensis, Plicatounio （Plicatounio） naktongensis, Unio longus and Sphaerium （Sphaerium） chintaoense are good in
