Figure 1From: Distribution of CO2 fluids in the Shimanto belt on Muroto Peninsula, SW Japan: possible injection of magmatic CO2 into the accretionary prismDistribution of the Shimanto belt and geological map of the Murotohanto subbelt. (a) Distribution of the Shimanto belt in SW Japan. (b) Geological map of the Murotohanto subbelt (Eocene-Oligocene) on Muroto Peninsula (after Lewis et al. 2000) showing sample localities along the eastern (E1 to E4) and western coasts (W1 to W5). Sample E4 was taken from a large ex situ block of pillow lava interpreted to be from the Miocene Shiina volcanic rocks within the Nabae subbelt (e.g., Hibbard and Karig 1990; Mizoguchi et al. 2009).Back to article page
