The best preserved and most complete lava flow sequences of the Central Atlantic Magmatic Province (CAMP) in Morocco are exposed in the Central High Atlas and can reach up to 300 m in thickness. Four distinct formations, emplaced in subaerial environ

Quantitative petrogenetic constraints on the Pliocene alkali basaltic volcanism of the SE Spain Volcanic Province
Autor: J. López-Ruiz, J.M. Cebriá, Miguel Doblas, J. Carmona
Publikováno v: Journal of Volcanology and Geothermal Research. 185:172-180
Alkali basalts of Pliocene age are the last episode of volcanism in the SE Spain Volcanic Province, postdating a complex series of Miocene calc-alkaline to ultrapotassic rocks. This volcanism is represented by small outcrops and vents NW of Cartagena

Geochemistry of the Early Jurassic Messejana-Plasencia dyke (Portugal-Spain); Implications on the Origin of the Central Atlantic Magmatic Province
Autor: Miguel Doblas, Línia Martins, José Munhá, J. López-Ruiz, J.M. Cebriá
Publikováno v: Journal of Petrology. 44:547-568
The Messejana±Plasencia dyke (MPD) is one of the largest doleritic dykes of the so-called Central Atlantic Magmatic Province (CAMP). Emplaced at 200Ma in the northernmost sector of this province, it crops out for some 530 km from South Portugal to C

Southward migration of volcanic activity in the central Mexican Volcanic Belt: asymmetric extension within a two-layer crustal stretching model
Autor: Roberto Oyarzun, Alvaro Márquez, Cristina de Ignacio, Miguel Doblas
Publikováno v: Journal of Volcanology and Geothermal Research. 112:175-187
Magmatic activity in the Miocene to present Mexican Volcanic Belt (MVB) is migrating to the south. Volcanic activity is associated with extension, which is being accommodated along a major, 1000-km-long, E–W-oriented continental rift. In turn, the

Geochemistry of the Quaternary alkali basalts of Garrotxa (NE Volcanic Province, Spain): a case of double enrichment of the mantle lithosphere
Autor: Miguel Doblas, Jan Hertogen, Rocío Benito, Roberto Oyarzun, J. López-Ruiz, J.M. Cebriá
Publikováno v: Journal of Volcanology and Geothermal Research. 102:217-235
The area of Garrotxa (also known as the Olot area) represents the most recent (700,000–11,500 y) and better preserved area of magmatic activity in the NE Volcanic Province of Spain (NEVP). This region comprises a suite of intracontinental leucite b
