ジャーナル オープンアクセスThe loose sediments at Fukakusa, southeast Kyoto, are recognized to be the Osaka Group by discovering the Azuki-Tuff and the Pink-Tuff. The Osaka Group at this area consists of gravels, sands, silts and clays. In this group 8 cycles exist and the upper four cycles have four marine clays and the lower four cycles have non-marine clays. It is 130 m in thickness and is marginal sediments in the Kyoto Basin. The marine molluscan fossils occur mainly from the seventh cycle and the plant fossils from the first and the fourth cycles. The Kuragatani Formation and the Momoyama Gravel, unconformably overlie the Osaka Group and they may correspond to the Manchidani Formation and the Meimi Gravel (the higher terrace deposits) respectively.抄録全体を表示PDF形式でダウンロード (1039K) -

ジャーナル オープンアクセスThe Hanaizumi Bed subjected here is the river terrace deposits in which many mammalian fossils are included, and is distributed at about 70 km north of Sendai City. The Tertiary strata of Miocene to Pliocene and terrace deposits in this area, experienced flexure upheaval in late Pliocene and Quaternary river erosion, resulting in present surface configuration. The Hanaizumi Bed containing fossils deposited in the valley incised in the Tertiary strata. The site of the excavation is situated on the middle terrace plain. Terrace deposits are subdivided into the Hanaizumi Bed composed of peat, sand and clay, and the superposed Alluvial Deposit with a hiatus between them. The occurrence of the mammalian bones is the "Tepee rock" type in swampy deposits. No artificial stone and bone tools were found. From fossil floral view point, the temperature during the deposition of the Hanaizumi Bed is estimated about 5-7℃ cooler than the annual average temperature of the present day. From palaeontological, archaeological and sedimentological view points, the geological age of the Hanaizumi Bed is considered as Warm Glacial Age. The result of C-14 dating suggests the Wurm II Stage.抄録全体を表示PDF形式でダウンロード (999K) -

ジャーナル オープンアクセスIn southwestern Japan, three metamorphic belts, the Sangun, the Sanbagawa and the Ryoke ones, are located with parallelism. Of these, the Sangun and the Sanbagawa metamorphic belts are considered to be two branches of one and the same metamorphic belt and to be conjugated in northern Kyushu, judging from the geologic age of their original sediments, their metamorphic ages, the type of their metamorphisms and their distributions. This metamorphic belt is poiyaxial with northern and the southern synclinoria. At present, the former is occupied by the unmetamorphosed Paleozoic sediments including the Akiyoshidai and the Taisyakukyo limestone formations and the latter by the Ryoke metamorphic and granitic rocks. The differences in petrological characters between these two branches depend probably upon the scale of geosynclinal subsidence. It proceeded with far larger scale in the Sanbagawa belt than in the Sangun one. Consequently, the Sangun metamorphic belt consists mainly of the rocks of the green schist fades, whereas the Sanbagawa belt is characterized by the glaucophanitic metamorphism. Moreover, even in the Sanbagawa belt, the subsiding movement in the area to the west of central Kii peninsula shows a distinct difference from that of the eastern part. In the western part, the Sanbagawa belt was differentiated into the intermediate upheaval zone and its both-sided subsiding zones. The subsidence was conspicuous in the northern subsiding zone. On the other hand, in the eastern part of the belt including the eastern Kii peninsula, the subsidence proceeded uniformly. Consequently, in the eastern part of the Sanbagawa metamorphic belt, the distinct lawsonite and jadeite zones were formed, whereas in the western part, they are totally defect. Moreover, the northern subsiding zone in the western part consists of the rocks of the glaucophane schist and the epidoteamphibolite facies, whereas the intermediate upheaval and the southern subsiding zones are composed of the rocks of the green schist facies. After the middle Cretaceous age, severe acid plutonism attacked the Japanese Islands. Its forerunner occupied the unmetamorphosed part of the southern synclinorium of the older metamorphic belt mentioned above. This is the Ryoke metamorphic belt. The Ryoke metamorphism owes its main agency to the upheaval of the isogeothermal surface due to this plutonism.抄録全体を表示PDF形式でダウンロード (1087K) -
