How and when plume zonation appeared during the 132 Myr evolution of the Tristan Hotspot. [PDF]
Nat Commun, 2015 Increasingly, spatial geochemical zonation, present as geographically distinct, subparallel trends, is observed along hotspot tracks, such as Hawaii and the Galapagos. The origin of this zonation is currently unclear.

Volcanological aspects of the northwest region of Paraná continental flood basalts (Brazil) [PDF]
Solid Earth, 2015 There has been little research on volcanological aspects of Paraná continental flood basalts (PCFBs), and all investigations have mainly been concentrated on the internal portions of the lava flows.

Facies architecture and volcanological aspects of silicic rocks from the Palmas plateau, Brazil
Brazilian Journal of Geology, 2020 The nature of the extensive silicic units of the Paraná Igneous Province is still heavily debated. The silicic rocks that outcrop in the Palmas plateau (Southwestern Parana State) show aphyric texture and TiO2 < 0.86%, being classified as Palmas-type ...

Contrasting stress fields on correlating margins of the South Atlantic [PDF]
, 2015 The “passiveness” of passive continental margins across the globe is currently under debate since several studies have shown that these margins may experience a variety of stress states and undergo significant vertical movement post-breakup.

New insights on the occurrence of peperites and sedimentary deposits within the silicic volcanic sequences of the Parana Magmatic Province, Brazil [PDF]
, 2014 The PMP (Parana Magmatic Province) is characterized by lava flows of the Early Cretaceous Serra Geral Formation which covers about 75% of the Parana Basin (southern and southeastern Brazil), composed of a thick (up to 1600 m) volcanic sequence formed by ...

South Atlantic opening: A plume-induced breakup? [PDF]
, 2015 Upwelling hot mantle plumes are thought to disintegrate continental lithosphere and are considered to be drivers of active continental breakup. The formation of the Walvis Ridge during the opening of the South Atlantic is related to a putative plume ...
