Viluy traps
The Viluy trap is a large igneous province (LIP). It is located in eastern Siberia, just east of the more famous Siberian traps which erupted during the end of the Permian period causing the End-Permian mass extinction event (also known as the Great dying). In Siberia, these eruptions caused over a million square kilometers of basalt to form while rifting systems in Eastern Europe formed another million square kilometers of basaltic material.[1]
Potential extinction
[edit]
It first erupted during the Late Devonian period. It was long thought that the emplacement of these traps were a major contributor to the Late Devonian extinctions at the Frasnian–Famennian boundary. However the main eruptions occurred at an earlier date (366 ±5 to 381 ±5 Ma) than the extinction event while the secondary pulse occurred towards the end-Devonian.[1][2][3] Also, the traps eruptions occurred alongside or at a similar time to two other LIPs, the Kola LIP located on the Kola Peninsula and the Pripyat–Dnieper–Donets (PDD) LIP located in Eastern Europe.[4]
