Paleotemperatures from fluid inclusions and coal rank of carbonaceous material of the Tertiary formations in Northwest Kyushu, Japan
TL;DR: In this paper, a correlation between fluid inclusion temperatures and vitrinite reflectance as a rank parameter of coal is presented, and the minimum values of homogenization temperatures obtained in this study are at least regarded as representing temperatures attained by the sedimentary rocks during burial metamorphism.

Formation of coalbed methane and water-dissolved gas in Kushiro Coal Mine, Japan, based on isotopic compositions of gas, groundwater, and calcite
Shuji Tamamura,Takuma Murakami,Akio Ueno,Satoshi Tamazawa,Tamotsu Kiyama,Hidenori Inomata,Hiroyuki Matsumoto,Kagemi Uchida,Yoshiaki Suzuki,Jun Aizawa,Katsuhiko Kaneko +10 more
TL;DR: In this paper, the authors investigated the origin of coalbed methane and water-dissolved gas from Kushiro coal mine and their formation environments and found a positive correlation between δD(CH4) of the sampled gas and the groundwater.

Kinetic Study on Cr(VI) Reduction in Natural Water by Means of Flow Injection-Solid Phase Spectrometry (FI-SPS)
Teruhisa Tsuruhara,Kô Takehara,Kazuhisa Yoshimura,Shiro Matsuoka,Sulistyo Saputro,Jun Aizawa +5 more
TL;DR: In this paper, the kinetics of Cr (VI) reduction in natural water were investigated by means of FI-SPS using a flow-through cell packed with a cation exchanger.

Timing of hydrothermal activity estimated by radiometric ages of Cretaceous granitic rocks at the Watari Peninsula, Fukutsu City, Fukuoka Prefecture, northern Kyushu
TL;DR: In this article, the ages of the Kitazaki and Shikanoshima granitic rocks and veneer Oligocene sedimentary rocks, the Tsuyazaki Formation, were investigated.

Regional Patterns of Diagenetic Alteration in the Tertiary of the Kyushu-Korea Region: Implications for Plate Tectonics at the Eastern Asian Continental Margin
TL;DR: In this article, the degree of diagenesis can be attributed to two types of alteration: regional burial diagenisation in each locality was accelerated by additional heat supply from a zone of high paleotemperature in the Sea of Japan.
