“…1,3,5,8), which crop out in Val d'Adige on top of the Tregiovo beds and closes the cycle of the ''Athesian Volcanic Group'' (AVG), indicate that the discussed unit dates to about 277-274 Ma (Bargossi et al 2004;Morelli et al 2006;Schaltegger and Brack 2007;Marocchi et al 2008), i.e., according to the Permian timescale by Gradstein et al (2004), between a latest Artinskian-early Kungurian interval.…”

“…In the central sector of the Athesian Volcanic Group the magmatic activity started with andesitic lava flows (286.0 ± 3.0 Ma, U-Pb zircon age, Avanzini et al 2010) and ended with the extrusion of rhyolitic ignimbrites associated with the formation of large calderas (275.0 ± 4.9 Ma, U-Pb zircon age, Avanzini et al 2010). The first activity of the western sector, Monte Luco-Adige valley (Laugen-Etschtal) area, is rhyolitic (285.9 ± 1.6 Ma, U-Pb zircon age, Marocchi et al 2008). The volcanic piles contain a conglomeratic level, under which the lava flows are andesites, rhyodacites, and rhyolites, whereas above the conglomerate the volcanic products are rhyodacites and rhyolites, only.…”

The present-day configuration of the lithosphere in the eastern Alps and more broadly in the northern Adriatic zone, records a multistage geologic evolution that was active since Precambrian times. Major evolutionary events (e.g., ocean opening, collision, subduction, etc.) were marked by the emplacement of large quantities of magmatic products. In this paper we present an overview of the field, petrographic, and geochemical characteristics of the main plutonic and volcanic bodies outcropping in the northern Adriatic zone and spanning from Permian to Cainozoic. Geochemical and petrologic study of these igneous occurrences greatly helped unraveling the geologic history of this area.

Burial history and thermal maturity of Mesozoic rocks of the Dolomites, Northern Italy

Thermal maturity analyses provide a valid basis to reconstruct the burial and temperature history of sedimentary rocks. In combination with computer based modeling it is possible to quantify former overburden and erosional thickness. This study was carried out to analyze thermal maturity and elaborate the burial history of PermoMesozoic sediments of the Western Dolomites, Northern Italy. Based on their location in the non-metamorphosed Southern Alps of the Alpine realm, the Dolomites are well suited to study thermal maturation in a complex orogenic setting. Determination of maturity was carried out by vitrinite reflectance and solid bitumen reflectance measurements on a large number of samples as well as by RockEval pyrolysis. Vitrinite reflectance commonly ranges between 0.5 % VR r for Triassic and 0.76 % VR r for Permian sediments allowing an analysis of the lateral and vertical maturation patterns. Several 1D basin models were developed and calibrated by maturity measurements. Results show that deepest burial probably occurred at the end of Cretaceous times, followed by erosion of about 1800 ± 200 m. The estimated heat flows were moderate with 75 mW/m 2 for Jurassic rifting, 46 mW/m 2 for times of deepest burial and 41 mW/m 2 for present day.
