Figure 3From: Distribution of CO2 fluids in the Shimanto belt on Muroto Peninsula, SW Japan: possible injection of magmatic CO2 into the accretionary prismHistogram showing the molar proportions of CH 4 and CO 2 , X C O 2 (=CO 2 / (CO 2 + CH 4 )). In fluid inclusions from the eight localities on Muroto Peninsula. The X CO 2 value was determined from Raman spectra following the method of Burruss (2003).Back to article page
