Relationships between authigenic mineral transformation and variation in vitrinite reflectance during diagenesis: an example from the Tertiary of northern Kyushu, Japan
Published online by Cambridge University Press: 09 July 2018
Abstract
The Tertiary sequences in northern Kyushu, Japan, contain several types of zeolite and clay minerals together with carbonaceous materials. A correlation between authigenic mineral zones and vitrinite reflectance reveals the delay in mineral authigenesis relative to the increase in vitrinite reflectance compared with similar studies in other regions. This may be ascribed to causes such as high paleogeothermal gradient, and chemical composition of pore-waters and host sediment.
