Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure
Meteoritics &Planetary Science, EarlyView.Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

U-Pb SHRIMP zircon dating of Grenvillian metamorphism in Western Sierras Pampeanas (Argentina) : correlation with the Arequipa-Antofalla craton and constraints on the extent of the Precordillera Terrane [PDF]
, 2006 The Sierras Pampeanas of Argentina, the largest outcrop of pre-Andean crystalline basement in southern South America, resulted from plate interactions along the proto-Andean margin of Gondwana, from as early as Mesoproterozoic to Late Paleozoic times (e ...

Early Paleozoic tectonics of Asia: Towards a full-plate model
, 2017 Asia is key to a richer understanding of many important lithospheric processes such as crustal growth, continental evolution and orogenesis. But to properly decipher the secrets Asia holds, a first-order tectonic context is needed.

Discrete and continuous character-based disparity analyses converge to the same macroevolutionary signa. A case study from captorhinids [PDF]
, 2017 The relationship between diversity and disparity during the evolutionary history of a clade provides unique insights into evolutionary radiations and the biological response to bottlenecks and to extinctions.
