The status of Pannotia as an Ediacaran supercontinent, or even its mere existence as a coherent large landmass, is controversial. The effect of its hypothesized amalgamation is generally ignored in mantle convection models claiming the transition fro

The amalgamation of Pangea: Paleomagnetic and geological observations revisited
Autor: William J. Collins, Lei Wu, Sergei Pisarevsky, Cecilio Quesada, J. Brendan Murphy, Simon Williams, Zheng-Xiang Li, John W.F. Waldron
Publikováno v: GSA Bulletin. 133:625-646
The supercontinent Pangea formed by the subduction of the Iapetus and Rheic oceans between Gondwana, Laurentia, and Baltica during mid-to-late Paleozoic times. However, there remains much debate regarding how this amalgamation was achieved. Most pale

Reconstructing the pre–Variscan puzzle of Cambro–Ordovician basement rocks in the western Mediterranean region of Gondwana
Autor: Josep Maria Casas, J. Javier Álvaro, Cecilio Quesada
In today’s western Mediterranean region, Variscan and Alpine thrusts and shear zones combine to hamper a correct identification and palinspastic reconstruction of Cambro-Ordovician sequences. However, gap-related stratigraphic, climatically sensiti
