Organization of pre-Variscan basement areas at the north-Gondwanan margin [PDF]
International Journal of Earth Sciences, 2001 Pre-Variscan basement elements of Central Europe appear in polymetamorphic domains juxtaposed through Variscan and/or Alpine tectonic events. Consequently, nomenclatures and zonations applied to Variscan and Alpine structures, respectively, cannot be valid for pre-Variscan structures.

Journal of Maps, 2017 We present a structural geological map (1:14,000 scale) that covers a 100 km2 area of Variscan basement rocks exposed in central Sardinia. The mapped area is located between 39°56′20′′ N 9°04′59′′ E (northwestern corner) and 39°51′47′′ N 9°13′16′′ E ...

Late Cretaceous–early Palaeogene inversion-related tectonic structures at the northeastern margin of the Bohemian Massif (southwestern Poland and northern Czechia) [PDF]
Solid Earth, 2022 A brief, regional-scale review of the Late Cretaceous–early Palaeogene inversion-related tectonic structures affecting the Sudety Mountains and their foreland at the NE margin of the Bohemian Massif is presented and complemented with results of new ...

Geophysical Monograph Series, Page 169-190., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Uranium distribution in the Variscan Basement of Northeastern Sardinia [PDF]
Journal of Maps, 2015 We present a detailed map of uranium distribution and its uncertainties in the Variscan Basement of Northeastern Sardinia (VBNS) at a scale of 1:100,000. An area of 2100 km2 was investigated by means of 535 data points obtained from laboratory and in situ gamma-ray spectrometry measurements. These data volume corresponds to the highest sampling density

60 years of the Serbo-Macedonian Unit concept: From Cadomian towards alpine tectonic frameworks [PDF]
Geološki Anali Balkanskoga Poluostrva, 2020 The study represents a summary of the hitherto tectonic concepts revolving around a peri-Gondwanan fragment referred to as the Serbo- Macedonian Unit. The Serbo-Macedonian Unit as a gneiss-dominated basement segment is positioned in the proximity of the ...

Rifting and arc-related early Paleozoic volcanism along the North Gondwana margin: geochemical and geological evidence from Sardinia (Italy) [PDF]
, 2012 Three series of volcanic rocks accumulated during the Cambrian to Silurian in the metasediment-dominated Variscan basement of Sardinia. They provide a record of the changing geodynamic setting of the North Gondwana margin between Upper Cambrian and ...
