Geochemical zoning, mingling, eruptive dynamics and depositional processes; the Campanian Ignimbrite, Campi Flegrei caldera, Italy
TL;DR: The Campanian Ignimbrite (CI) is a large volume trachytic tuff erupted at 37 ka from the Campi Flegrei and composed of a fallout deposit overlain by ignimbrites.

TL;DR: The results confirm that the combined effects of a major volcanic eruption and severe climatic cooling failed to have lasting impacts on Neanderthal or early modern humans in Europe and infer that modern humans proved a greater competitive threat to indigenous populations than natural disasters.
Timing of magma extraction during the Campanian Ignimbrite eruption (Campi Flegrei Caldera)
Lucia Pappalardo,L. Civetta,S. de Vita,M. A. Di Vito,G. Orsi,Antonio Carandente,Richard V. Fisher +6 more
TL;DR: In this article, a core was used to observe the superposition of four pyroclastic flow units emplaced during the Campanian Ignimbrite (CI) eruption, which can be used to better constrain the chemical stratigraphy of the deposit and the compositional structure of the CI magma chamber.

Early Proterozoic dike swarms from western Uruguay: geochemistry, SrNd isotopes and petrogenesis
Jorge Bossi,Néstor Campal,L. Civetta,G. Demarchi,Vicente Antonio Vitorio Girardi,Maurizio Mazzucchelli,L. Negrini,Giorgio Rivalenti,A.R.S. Fragoso Cesar,Silvano Sinigoi,Wilson Teixeira,E. M. Piccirillo,M. Molesini +12 more
TL;DR: In this paper, the high LILE and LREE content is discussed in terms of crustal contamination of the melts or of the source, or of mantle metasomatism.

Thermal and geochemical constraints on the ‘deep’ magmatic structure of Mt. Vesuvius
TL;DR: A review of available and new isotopic data on rocks from Mt. Vesuvius together with geophysical and mineralogical data allow us to define a deep complex magmatic reservoir where mantle-derived magmas arrive, stagnate and differentiate, and to constrain a thermal model, which describes the history and present state of the reservoir and its surrounding rocks as discussed by the authors.
