Figure 12From: Distribution of U and REE on colloids in granitic groundwater and quality-controlled sampling at the Mizunami underground research laboratory Chondrite-normalized REE patterns of the groundwater during development of the (a) 09MI20 and (b) 10MI26 boreholes. Chondrite data are from Anders and Grevesse ([1989]). V/V 0 is the ratio of the replaced volume of the groundwater to the sampling interval volume in the boreholes.Back to article page
