331 ± 9 Ma emplacement age of the Soultz monzogranite (Rhine Graben basement) by U/Pb ion-probe zircon dating of samples from 5 km depth

 abstract = {Drilling at Soultz-sous-Forêts, France, conducted as part of the European ‘Hot Dry Rock’ Project, penetrated the Rhine Graben basement down to 5 090 m and revealed a porphyritic monzogranite. Chemical composition and REE patterns of three samples at 5 km depth indicate homogeneous composition with a slight vertical differentiation, suggesting stable P–T conditions after the magma emplacement. U/Pb ion-probe zircon dating provides an emplacement age at 331±9 Ma. This age is in agreement with those of the other intrusive granitoids in this part of the Variscan segment, indicating a period of intensive magmatic activity around 330 Ma.},
