Andrea Marzoli,Andrea Marzoli,Sara Callegaro,Jacopo Dal Corso,Joshua Davies,Massimo Chiaradia,Nassrrdine Youbi,Nassrrdine Youbi,Hervé Bertrand,Laurie Reisberg,Renaud E. Merle,Fred Jourdan +11 more
TL;DR: The Central Atlantic magmatic province (CAMP) consists of basic rocks emplaced as shallow intrusions and erupted in large lava flow fields over a land surface area in excess of 10 million km2 on the supercontinent Pangaea at about 201 Ma as discussed by the authors.
Journal ArticleDOI
Geochemistry and Sr, Nd, Pb isotopic composition of the Central Atlantic Magmatic Province (CAMP) in Guyana and Guinea
TL;DR: In this article, two areas of the Central Atlantic Magmatic Province (CAMP) are studied: French Guyana/Surinam (South America) and Guinea (West Africa), in order to document the petrogenesis and geodynamical significance of high-Ti and low-Ti basaltic magmas from the CAMP.

40Ar/39Ar ages and Sr–Nd–Pb–Os geochemistry of CAMP tholeiites from Western Maranhão basin (NE Brazil)
Renaud E. Merle,Andrea Marzoli,Hervé Bertrand,Laurie Reisberg,Chrystèle Verati,Catherine Zimmermann,Massimo Chiaradia,Giuliano Bellieni,Marcia Ernesto +8 more
TL;DR: In this paper, the authors presented the occurrence of two sub-groups among the high-Ti tholeiites in the Western Maranhao basin, i.e., the low-Ti (TiO2 3 wt.%) WMBT and the higher-Ti WMT.

Spatial and temporal variation in Late Cenozoic back-arc volcanic rocks, Aegean Sea region
TL;DR: In this article, the age and major and trace element geochemistry of these back-arc volcanic rocks are reviewed from the literature: where necessary, new geochemical analysis have been made.

TL;DR: In this article, the geochemical characteristics of CAMP basalts from Triassic-Jurassic basins in northeastern USA and Nova Scotia (Canada) have been analyzed and three chemical groups are defined: the Rapidan sill, which has 206Pb/204Pbini.

Trace element and isotopic effects of combined wallrock assimilation and fractional crystallization
TL;DR: In this paper, the mass assimilation rate is an arbitrary fraction(r) of the fractional crystallization rate, where r < 1 is a combination of zone refining and fractional scaling.

Abundance of chemical elements in the continental crust: a new table
TL;DR: In this article, a table of element abundances in the continental crust, calculated on the basis of a 1:1 mixture of granite and basalt abundances, is presented.

Partition coefficients of rare-earth elements between igneous matrix material and rock-forming mineral phenocrysts—II
TL;DR: In this paper, solid-liquid partition coefficients between phenocrysts and the host lavas have been measured for rare-earth elements by an isotope dilution technique and the consistency of much of the data suggests that most of the phenocryst crystallized under equilibrium, or quasi-equilibrium, conditions.
Journal ArticleDOI
Chemical Characteristics of Oceanic Basalts and the Upper Mantle
TL;DR: In this article, it was shown that oceanic tholeiites are either complete melts of the upper mantle or are generated from a mix of this tholeite and a magnesium-rich peridotite or dunite in proportions up to perhaps 1:4.

Geochemical characteristics of mid-ocean ridge basalts
TL;DR: In this article, a strong correlation exists between percent TiO 2 (proportional to amount of melting) and Al 2 O 3 /TiO 2, CaO/TiO2 ratios of these close to primary MORB, indicating a progressive release of Al and Ca from the mantle source.
