Granitic rocks are durable materials sought after for the production of road and railroad aggregates. Granitic bedrock commonly, however, includes gabbroic components, which may enhance or decrease the aggregate performance. This study evaluates the

The Precambrian shield in southern Sweden exposes a granitic bedrock segment that represents a part of an ancient eroded mountain belt and expose a gradual change in metamorphic grade from cold (800°C) and partially molten sections at the west coast

New thermo and geochronological constraints on the Pliocene-Pleistocene eruption history of the Paipa-Iza volcanic complex, Eastern Cordillera, Colombia

Autor: Matthias Bernet, Sergio Amaya, Mary Luz Peña, Cindy Urueña

Publikováno v: Journal of Volcanology and Geothermal Research. 327:299-309

The Paipa-Iza volcanic complex is the only volcanic edifice in the Eastern Cordillera of Colombia. Zircon fission-track and U Pb data from deposits of two eruption epochs presented in this study constrain the time of volcanic activity between 5.9 Ma
