Stratigraphy and petrogenesis of the Parana continental flood basalts, southern Brazil [PDF]

open access: yes, 1990
The Early Cretaceous (~130 Ma) ParanĂ¡ lavas of South America represent the largest preserved example of a continental flood basalt (CFB) province, with a present area in excess of 1.2 x 106 km2. Magmatism is dominated by tholeiitic basalts (> 90 %), with minor rhyolites as a late-stage feature along the continental margin. The basaltic magmas show a

Global tectonic studies: Hotspots and anomalous topography [PDF]

open access: yes
Volcanic activity on Earth and its secular variations are compared with that on other terrestrial planets. Activity at divergent, transform, and convergent plate margins is described with particular emphasis on hot spots and flood basalts. The timing and

Deccan volcanism and K-T boundary signatures [PDF]

open access: yes
The Deccan Traps in the Indian subcontinent represent one of the most extensive flood basalt provinces in the world. These basalts occur mainly as flat-lying, subaerially erupted tholeiitic lava flows, some of which are traceable for distances of more ...

Early impact basins and the onset of plate tectonics [PDF]

open access: yes
The fundamental crustal dichotomy of the Earth (high and low density crust) was established nearly 4 billion years ago. Therefore, subductable crust was concentrated at the surface of the Earth very early in its history, making possible an early onset ...
