EGS-relevant review of metallogenesis, CHPM2030 Deliverable D1.1

In the provisioned CHPM technology an enhanced geothermal system would be established on a deep metal-bearing geological formation, which would be conducted in a way that the co-production of energy and metals could be possible. The aim of this study is to provide a metallogenic background for the potential development of this technology. 

In the document the ore formation processes and the metallogenic provinces of Europe are reviewed, considering the relevancy with the EGS application, in order to identify the possible zones where the CHPM technology can be applied. 

As the distribution of metallogenic provinces strongly correlates with the tectonic setting, four large metallogenic provinces can be identified within Europe: (1) Precambrian Fennoscandian Shield province, (2) Early Paleozoic Caledonian province, (3) Late Paleozoic Variscan province, (4) Mesozoic-Cenozoic Alpine province. The prospective zones or formations for the CHPM technology are assessed in each metallogenic province. Additionally to the mineralised intrusive bodies, thick sedimentary successions in extensional structures and deep-rooted regional fault zones can be also target areas both for the elevated heat flow and mineralisation potential from deep, fertile zones.
