Fluorine-rich hydrogarnet, prehnite and pumpellyite in monzodioritic basement of the Rhine Rift Valley produced by in-situ low-grade metamorphism at 200 °C and 5 km depth
Abstract The Basel-1 geothermal deep well has been drilled in 2006 to a final depth of 5 km. The recovered core material from 4.9 km depth shows coarse grained biotite-hornblende quartz-monzodiorite from the Variscan basement. The primary igneous rock is locally altered and contains prehnite, pumpel...
