Persistent Amazonian and West African detrital zircon signature in the northern Mauritanide Belt Open
We provide new detrital zircon U/Pb geochronological data from nine samples of Neoproterozoic–Cambrian metasedimentary rocks of the northern Mauritanide Belt, aiming at constraining depositional ages and provenance in the paleotectonic con…

Tectono-metamorphic interaction between the upper mantle and lower crust during continental rifting in the western Betic Cordillera Open
Recent geological mapping in the Ronda peridotites (Betic Cordillera, S Spain) has unveiled a consistent field correlation between lower crustal metamorphic units and specific tectono-metamorphic domains of the ultramafic massif. Mylonitic…

Reorganization of Northern Peri-Gondwanan Terranes at Cambrian–Ordovician Times: Insights from the Detrital Zircon Record of the Ossa-Morena Zone (SW Iberian Massif) Open
The Ossa-Morena Zone constitutes a fringe Gondwana-related terrane all along the Paleozoic. This continental block has been classically interpreted as being attached to a portion of the northern Gondwanan margin located close to the West A…

A review of U-Pb detrital zircon systematics from Cambrian- Lower Devonian rocks of the Moroccan Meseta Open
U-Pb geochronological analysis of detrital zircon grains is a powerful tool to decipher the pre-Mesozoic paleogeography. In this work, we present a sediment provenance study based on a compilation of 41 Cambrian-Early Devonian siliciclasti…

Submarine Basaltic Magmatism in the Subbetic Basin (Southern Spain): Insights into Melt-Weakening Processes during Mesozoic Continental Rifting Open
Mantle-derived volcanic rocks from the Subbetic hyperextended basin in SE Spain provide new insights into the composition and mechanical behavior of the mantle during continental rifting. The present study describes a sequential restored c…

Gold in the Farallones Block of the Shale-Hosted, Clastic-Dominated Castellanos Zinc-Lead Deposit (Northwest Cuba) Open
The Zn-Pb ores of the Castellanos shale-hosted, clastic-dominated deposit in northwest Cuba average nearly 1 g/t Au, with local maximum concentrations up to 34 g/t Au. This deposit is stratiform with respect to the bedding in the host blac…

Tectonic Evolution of the Eastern Moroccan Meseta: From Late Devonian Forearc Sedimentation to Early Carboniferous Collision of an Avalonian Promontory Open
The deformed Paleozoic succession of the Eastern Moroccan Meseta crops out in relatively small and isolated inliers surrounded by Mesozoic and Cenozoic rocks. Two of the largest inliers (Mekkam and Debdou) are characterized by a monotonous…

Deciphering the metamorphic evolution of the Pulo do Lobo metasedimentary domain (SW Iberian Variscides) Open
The Pulo do Lobo domain is one of the units exposed within the orogenic suture zone between the Ossa-Morena and the South Portuguese zones in the SW Iberian Variscides. This metasedimentary unit has been classically interpreted as a Rheic …

Deciphering the metamorphic evolution of the Pulo do Lobo metasedimentary belt (SW Iberian Variscides) Open
The Pulo do Lobo belt is one of the units related to the orogenic suture between the Ossa-Morena and the South Portuguese zones in the SW Iberian Variscides. This metasedimentary unit has been classically interpreted as a Rheic subduction-…

Oblique collision and deformation partitioning in the SW Iberian Variscides Open
Different transpressional scenarios have been proposed to relate kinematics and complex deformation patterns. We apply the most suitable of them to the Variscan orogeny in SW Iberia, which is characterized by a number of successive left-la…
