| 抄録 | A case study on persistent appearance of the ensemble of precipitation bands in the warm sector of the Baiu front in Kyushu District, the western part of Japan around 19 June 2001 was performed based on the operational observational data. Around 00UTC (09JST) 19 June when the Baiu front on the surface weather map was still located about a few 100kms to the north of Kyushu, the number and the total area of the meso-β or γ-scale line-shaped precipitation bands increased around Kyushu rapidly. These precipitation bands had been sustained there and gradually gathered each other to change into the Baiu frontal precipitation zone extending from the northern Kyushu to Seto-Naikai (Seto Inland Sea) around 09UTC (18JST) 19 June (the intense rainfall zone was still located in the warm sector of the Baiu front). Until ~09UTC (18JST) 19 June, the moist air flow with the latently unstable stratification had been sustained around Kyushu corresponding to the low-level southerly wind toward the surface Baiu front to the north of Kyushu. This large-scale situation would contribute greatly to the maintenance of the ensemble of the line-shaped precipitation bands in the warm sector of the Baiu front. |

| 抄録 | Erect fossil stumps were found from the outcrop of the Upper Triassic Hinabata Formation, the uppermost part of the Nariwa Group at Hinabata, Nariwa-cho,Takahashi City, Okayama Prefecture, SW Japan. They are evidence of the oldest fossil forest in Japan. The Upper Triassic Nariwa Group is mostly composed of non-marine deposits except the marine Jito Formation and characterized by the abundance in plant fossils. The marine Jito Formation is characterized by occurrence of Norian Monotis ochotica. On the basis of detailed observation of the occurrence of erect fossil stumps, as well as sedimentary facies of fossil-bearing unit, the fossil forest was interpreted to have grown on the top of the natural-levee units. One of the erect fossil stumps was identified as Xenoxylon sp. |

| 抄録 | Ordinary Kriging, OK, and Regression Kriging, RK, are the spatial statistical methods that are possible to estimate a horizontal distribution in a study area from discrete data. OK is the method which takes account of only spatial auto-correlation structure of the data, while RK is the method which takes account of an interrelationship between spatial auto-correlation structure and some auxiliary variables to minimize the estimation error. Analytical processing for OK and RK methods was performed by the R-Language (R Core Team, 2012) and its some additional libraries. The auxiliary variables required to perform RK method were prepared by a GIS application, Quantum GIS (Quantum GIS Development Team, 2012). The 3-dimensional geographic representation of the estimation maps was performed by the Google Earth (Google, 2012). In this report, OK and RK methods were applied to one of the Earth scientific information, SPM (Supended Particulate Matter). Then, these methods were considered by comparing two estimation maps, and finally considered qualitatively by displaying these maps in the Google Earth. |

| タイトル（別表記） | The temperature and pressure conditions of synthetic Sibirskite and Parasibirskite |

| 抄録 | Sibirskite (CaHBO ) and parasibirskite ₃ are in the relation of polymorphism, these are regarded as the alteration products of takedaite (Ca₃B₂O₆), occurs at Fuka mine, Okayama Prefecture. The synthesis of parasibirskite was reported by the Schäfer (1968a, b) etc. and the synthesis of sibirskite was reported by the Sun et al. (2011). To determine the formation condition of sibirskite and parasibirskite in the natural, they were synthesized from the natural takedaite (Ca₃B₂O₆). As a result, both of sibirskite and parasibirskite were formed by the duration time of 7 days with 1000 kg/cm2 and 300 oC, on the other hand, only sibirskite was formed by the duration time of 14 days with the same condition. In addition, the mixtures of sibirskite and parasibirskite were examined under the various temperatures and pressures of hydrothermal conditions. As a result, the upper limit of the stable temperature and pressure conditions of sibirskite was estimated between 350 oC and 400 oC at 1500 kg/cm2, and between 400 oC and 450 oC at 500 kg/cm2 . In the higher temperature than the condition, sibirskite were changed into shimazakiite (Ca₂B₂O₅). |

| タイトル（別表記） | Folded structure of the Carboniferous Ko-yama Limestone Group, Akiyoshi Belt, SW JAPAN |

| 抄録 | The fold structure of the Akiyoshi Belt was analyzed in Kawakami-cho, Okayama Prefecture, where the Lower Carboniferous to Middle Permian Ko-yama Limestone Group (Yokoyama et al., 1979), Permian Yoshii Group (Sano et al., 1987) and Triassic Nariwa Group (Teraoka, 1959) are distributed. The Nariwa Group unconformably covers the Paleozoic successions (Otoh, 1985). The Lower Carboniferous to Middle Permian Ko-yama Limestone Group, dated by foraminifers and fusulinids (Yokoyama et al., 1979), is mainly composed of massive limestone with basic volcanics, acidic tuff and chert. The Paleozoic successions of the Akiyoshi Belt were folded during the Middle to Late Permian (Suzuki et al., 1990). Strata of the Ko-yama Limestone Group generally strike E-W and dip to the north. The Hoya section about 300 m thick is composed of limestone, basic tuff, chert and acidic tuff, limestone, basic lava and tuff in ascending order. In this section, Ishida et al. (2012) recognized a nearly complete conodont faunal succession ranging from the upper Visean to the lower Moscovian. The faunal succession indicates younging southward, and the strata are overturned. A folded strucuture of tight overfold with north-dipping axial plane was reconstructed. Similar style of small scale overfolds of banded chert and turbidite were observed in the overlying Yoshii Group. |

| フルテキストURL | esr_019_1_001_004.pdf |
| 著者 | 鈴木 茂之| |
| 抄録 | Quaternary peat beds from bore-hole samples deliver information to reconstruct paleoenvironment. Altitudes of dated non-marine peat beds and marine beds allow to be created a sea-level curve. 4 peat beds (A to D) are identified from the uppermost Pleistocene to Holocene deposits of the Okayama Plain. They thought to be deposited at stable events during sea-level change. |
