The volcanic activity of the Euganean Hills is part of the Tertiary Magmatic Province Veneta, and consists mainly in the issue of basic and acid products and over a period of time between the late Eocene and the Oligocene.

Abstract
The volcanic activity of the Euganean Hills is part of the Tertiary Magmatic Province Veneta, and consists mainly in the issue of basic and acid products and over a period of time between the late Eocene and the Oligocene. The basic rocks are represented mainly by basalts. The geochemical study by X-ray fluorescence conducted on samples of Monte Oliveto and Monte Lovertino showed a strong bimodal character between these: a general enrichment in alkali and incompatible elements for the Lovertino group and a decidedly more tholeiitic character for the Oliveto basalts. The fractional crystallization was discarded as a possible link between the two magmas, as observed by modeling MELTS, in favor of a distinct parental magma issued from a similar mantle source yet at different melting degree (lower for Lovertino) or melting depth (deeper for Lovertino).File | Dimensione | Formato | |
