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,即频临古太平洋的日本西南部的外带因地势低而多被海水覆盖,在牧户/庄川和黑龙江东部存有遭受海侵的浅而窄的海湾,凡兰吟期,特别是欧特里沃期/巴列姆期之前,中国东北韩国东南部日本西南部陆块为受造山运动引起的隆起和沉降活动影响的高低不平的高原,经受了广泛而长期的剥蚀。多数含有包括熔岩和凝灰岩在内的火山岩,并与北东北北东方向的断裂带近于平行分布的非海相白垩纪盆地直至欧特里沃期/早巴列期(有些地区可能稍早(凡兰吟期))(134～126Ma),即华北克拉通破坏的高峰期(130～120Ma)才形成。这一现象表明,这些盆地受断裂,特别是伴随有强烈火山喷发和时而局部海侵的沿着古太平洋西北缘和郯庐断裂带的构造运动的控制。
Based on the comparison of non-marine and marine facies, especially the common marine and non-marine mollusk fossils, combined with radioisotope dating, eastern China’s eastern Heilongjiang and western Liaoning, the Gyeongyang Basin in southeast Korea, southwestern Japan The Gushu northern part of Gifu County / Zhuangchuan area and the Early Cretaceous strata of the Tokushima and Mukokuqu areas in the Shikoku of the Gifu Prefecture were contrasted. The era of non-marine molluscs produced in these formations was also constrained. The famous Longpaogou and Jixi herds in the northeastern coal-bearing strata of China and the Rehe group, which are rich in Jehol biota and fauna, are the Etrurvuo / Balmain periods of the Aptite period. Their overburden Birch group and Sunjiawan group for Albin. The Hedong Group outside the Southwest of South Korea and the Jieyang Group other than the Jindong Formation are the Alp period, and the Doupu Formation that is not integrated under the new caves is mainly the Autrey Valley. The animal husbandry in the southwestern part of Japan / the Shouchu group in the Zhuangchuan area and the Wuchuan group in the outlying areas of Tokushima and Mukden areas are All-Oliver period Albinism. The age of Cuniopsis kihongi, Nakamuranaia leei, Koreanaia cheongi, and Trigonioides (Wakinoa) tetoriensis is the Early Valerian period of the Autorivsky period. Viviparus onogoensis, Unio ogamigoensis, Myrene (Mesocorbicular) tetoriensis, and Tetoria (Tetoria) yokoyami are the Autotribs Apter period. Arguniella cf.quadrata, A..cf.ventricosa, Sphaerium (Sphaerium) anderssoni, Probaicalia vitimensis, and Pr.gerassimovi are the Aotevir / Permut phases of Aptian. Nakamuranaia chingshanensis, Plicatounio (Plicatounio) multiplicatus, Sphaerium (Sphaerium) coreanicum, and Micromelania katoensis are alpine phases of the Aptus phase. Nippononaia sinensis, Nip.tetoriensis, Nip.ryosekiana and Trigo-nioides (Wakinoa) wakinoensis are symbols of the Apter period. Trigonioides (Trigonioides) quadratus, T. (T.) heilongjiangensis, Plicatounio (Plicatounio) naktongensis, Unio longus and Sphaerium (Sphaerium) chintaoense are late fifties Albuquerque or Albino flag fossils. The similarities in the proximity of non-marine facies, especially freshwater molluscs, in northeastern China, southeast Korea and southwestern Japan suggest that the three areas were connected during the Early Cretaceous and were in the same water system. However, during the Albte of the Eighthrvoir period, the eastern part of this landmass, the outer belt of the southwestern part of Japan which borders the ancient Pacific Ocean, was mostly covered by seawater because of the low altitude. In the pastoral households / Zhuangchuan and the eastern part of Heilongjiang There are shallow and narrow bays that have been transgressed by the sea, and during the Vanran period, especially before the Autrevois / Balmain period, the land mass in the southwestern part of northeastern Korea in southeastern Korea was uplifted and subsided due to orogeny The rugged plateau that has been affected has undergone extensive and long-term erosion. Most of them contain volcanic rocks, including lava and tuff, and are close to the late Cretaceous to the Eritrean / Early Paleozoic near non-marine Cretaceous basins parallel to north-northeastern and northeastern faults (some areas may be earlier Van Lan Yin period) (134 ~ 126Ma), that is, the peak of North China craton destruction (130 ~ 120Ma) was formed. This phenomenon indicates that these basins are subject to tectonic movements along the northwestern margin of the ancient Pacific Ocean and the Tan-Lu fault zone, especially with strong volcanic eruptions and sometimes local transgressions.
