About 500 limestone samples with orientation were obrained from the southwestern part of the Akiyoshi Limestone Group. Many limestone blocks which contain ammonoids also collected.The limestone samples were cut and polished for sedimentological analysis and many thin-sections made for the determination of fusulines.Some important outcrops of uncon formity were found in the Fusulinella biconica Zone and the boundary of the Pseudojusulinella hidensis and Protriticites montiparus Zone.The sea level fall near the boundary which are most probably correlated with that of standard Moscovian and Kasimovian on the basis of ammonoids and fusulines is in excess of 50 meters.

在秋吉石灰岩群西南部采集了约500个有方向性的石灰岩样品。还收集了许多含有菊石的石灰岩块。对石灰岩样品进行了切割和抛光以进行沉积学分析，并制作了许多薄片以测定fusulines。在Fusulinella biconica带以及Pseudojusulinella hidensis和Protriticites montiparus带的边界发现了一些重要的不整合露头。边界附近的海平面下降最有可能是相关的 与基于菊石和fusulines的标准莫斯科和卡西莫夫的距离超过50米。
