Comment on "Stratigraphic architecture of sedimentary basin induced by mantle diapiric upwelling and eustatic event" by Yamada and Nakada [Tectonophysics 415 (2006) 1033121]

Yamada and Nakada (2006) examined the stratigraphic architecture of sedimentary basin induced by mantle diapiric upwelling and eustatic event. They applied their model to the Karatsu-Sasebo coalfield in northwest Kyushu, southwest Japan. In the application, a neutral stress regime was assumed during the subsidence and the uplift of the coalfield. The history of activities of the Sazagawa Thrust at the Kita-Matsuura peninsular in the coalfield, however, suggest that NW Kyushu would have been al least twice under the compressive stress regime, suggesting that the assumption of the neutral stress regime is not the case for the Karatsu-Sasebo coalfield. Therefore, their application for the Karatsu-Sasebo coalfield has to be revised.
