Enhancement of permeability activated by supercritical fluid flow through granite

Nohara, Tsuyoshi ; Uno, Masaoki*; Tsuchiya, Noriyoshi*

Amphibole-plagioclase thermometry was applied to estimate the temperature of a glassy vein as approximately 700. The results of observations of the rock core revealed that of supercritical fluid flow was microfracture filling with hornblende and plagioclase. The current high permeability was recognized to be microfracture network. A high-angle fracture of chlorite filling in combination with an open fracture was recognized as characteristics of a high-permeability type.
