The lithospheric architecture of passive margins is crucial for understanding the tectonic processes that caused breakup Gondwana. We highlight evolution South Atlantic by a simple thermal lithosphere-asthenosphere boundary (LAB) model based on onset and cessation rifting, crustal thickness, stretching factors. simulate thinning select LAB as T = 1,330°C isotherm, which calculated 1D advection ...

The age of the Talchir Formation corresponding to lower part Gondwana (Permo–Carboniferous) Sequence in India is revised light palynostratigraphic data associated with radiometric dating generated Gondwana. New was from seven samples obtained Well 131, located Penganga area Wardha Valley Coalfield (Maharashtra State, central India). Two assemblages were demarcated based on stratigraphic distrib...

This study compiles the U-Pb and 40Ar/39Ar geochronology of metasedimentary, migmatitic granitic rocks Sierra Albarrana Domain, based on data recently published by authors together with other bibliographic sources. Maximum depositional ages (MDA) magmatic metamorphic events are discussed. MDAs suggest that this domain was deposited during middle Cambrian (ca. 511) zoned zircon grains indicate m...

Carboniferous magmatism in southwestern Iberia was continuously active for more than 60 m.y. during the development of Appalachian-Variscan belt North America, Africa and Western-Central Europe. This collisional orogen that records closure Rheic Ocean is essential to understanding late Paleozoic amalgamation Pangea supercontinent. However, oblique convergence between Laurussia Gondwana lasted f...
