Meteoritics &Planetary Science, EarlyView.Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

The Geologic Features of the Occurrence of Copper in North America [PDF]
, 1933 Copper is of such widespread natural occurrence in North America and there are so few metal-mining districts that have not contributed to its production that it is obviously necessary in any brief general treatment of the geology of the copper deposits ...

Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]
, 2017 The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

Fault systems in multiply deformed regions of Eurasia
Russian Journal of Earth Sciences, 2023 We have studied the orogenic fragile deformation of the upper Earth’s crust of several areas of the Eurasian continent, where deformations have occurred many times – in the Tian Shan and Altai-Sayan regions of the Central Asian Paleozoic Fold Belt and in

Detrital zircon from a late Paleozoic accretionary complex of SW Iberia (Variscan Belt): History of crustal growth and recycling at the Rheic convergent margin [PDF]
, 2012 In this study we present new U-Pb ages of detrital zircons from greywackes and quartzites of the Pulo do Lobo Anticline (PLA) that have been interpreted to represent a Late Paleozoic accretionary complex in SW Iberia.
