Limestone blocks contained in the Permian to Early Cretaceous accretionary complexes of Japan yield various kinds of Permian and Triassic foraminifers that provide restrictions considering the plate movement of the Panthalassan-originated seamounts, and tectonics and paleobiogeography of Paleozoic to Mesozoic in East Asia. This research program was performed to understand the field occurrences, lithologic properties, and fossil assemblages in confined and representative limestone blocks of each of the accretionary terranes of Japan that are most suitable for studying time- and space-distribution of Paleozoic and Mesozoic foraminifers in the Circum-Pacific regions and also have useful geologic data for the present study. Biostratigraphic distribution, faunal composition, and taxonomic diversity of foraminifers in relation to limestone lithologies were clarified in many of these limestone blocks. This research program discussed and revealed on paleobiogeography of Late Paleozoic foraminifers, depositional site of limestone and limestone-bearing strata, and post-depositional tectonic modification based on the careful examination of phylogenetic relationships, time- and space-distribution, degree of similarities of diagnostic species and faunal composition of these foraminifers, adding results of many unpublished data and literature survey to those obtained in this research program. Further time and information are necessary to lead the final conclusion to explain the aim of this program that is focused on the origin, transportation and emplacement of these exotic limestone blocks. Eighteen papers and many lines of new information deeply related to the aim of this program were obtained in these three years as the results of active promotion of this research program that was placed as the extension and further development of my serial work concerning evolution and paleobiogeography of Late Paleozoic and Mesozoic foraminifers.

日本二叠纪至早白垩世增生杂岩中的石灰岩块产生了各种二叠纪和三叠纪有孔虫，考虑到源自 Panthalassan 的海山的板块运动以及东亚古生代至中生代的构造和古生物地理，这些有孔虫提供了限制。该研究计划的目的是了解日本每个增生地体的受限和代表性石灰岩块中的现场产状、岩性特征和化石组合，这些区域最适合研究环太平洋地区古生代和中生代有孔虫的时间和空间分布，并为当前的研究提供有用的地质数据。在许多这些石灰岩块中，澄清了与石灰岩岩性相关的有孔虫的生物地层分布、动物区系组成和分类多样性。本课题在认真研究有孔虫的系统发育关系、时空分布、诊断种的相似程度、动物区系组成的基础上，在大量未发表的资料和文献调查的基础上，对晚古生代有孔虫的古生物地理学、石灰岩和含灰岩地层的沉积场所以及沉积后的构造改造等问题进行了探讨和揭示。 研究计划。需要更多的时间和信息来得出最终结论，以解释该计划的目标，该计划的重点是这些奇异石灰石块的起源、运输和安置。作为我晚古生代和中生代有孔虫进化与古生物地理学系列工作的延伸和进一步发展，我积极推进本研究项目，三年来共获得与本项目目标密切相关的十八篇论文和多条新信息。
