In situ trace elements and U–Pb ages determination of zircons from diorite and anorthosite dykes intruding the Finero Phlogopite Peridotite (Ivrea-Verbano Zone, Southern Alps)

Bonazzi, Mattia | Ogunyele, Abimbola, Chris | Giovanardi, Tommaso | Mazzucchelli, Maurizio | Zanetti, Alberto

2023

Zircon grains were separated from diorite and anorthosite dyke swarms intruding the mantle body of Finero Phlogopite Peridotite (Northernmost tip of the Ivrea-Verbano Zone, Southern Alps). All the dykes are highly discordant with respect to the mantle peridotite foliation and crop out along the...

Nature of the mantle-crust transition in the Finero Complex (Ivrea-Verbano Zone, Southern Alps)

Lopez, Maria | Zanetti, Alberto | Tommasi, Andréa | Langone, Antonio | Padrón Navarta, Josè Alberto | Vauchez, Alain | Carafa, Michele Matteo Cosimo

2025

The Finero Complex (northern Ivrea-Verbano Zone; Southern Alps) has well-exposed contacts between rocks of the upper mantle and lower continental crust. The core of the Complex is composed by the Finero Phlogopite Peridotite (FPP) mantle unit, which is wrapped out by an intercalation of mafic...

Laser ablation inductively coupled mass spectrometry trace elements analyses of Li-rich micas of Pan-African pegmatites in Mozambique

Bunzula, Violeta Lavínia | Müller, Axel | Erambert, Muriel | van Schijndel, Valby | Schulz, Bernhard | Götze, Jens | Gilbricht, Sabine | Sláma, Jiří | Simonsen, Siri

2025

This data report presents the in-situ LA-ICP-MS trace element geochemistry of the micas of the Pan-African rare-element pegmatites of the Alto Ligonha Pegmatite District in northern Mozambique. The pegmatites contain Li-rich micas and primary Li aluminosilicates, such as spodumene. Five Alto...

Electron microprobe analyses of quenched melts (now glass), chromite, and olivine to determine the role of contamination on chromite crystallization in ultramafic magmas

Keltie, Erin | Brenan, James

2025

The data were generated in two labotories of the Dalhousie University in Halifax during a series of experiments to determine the solubility of chromite in komatiite mixed with different crustal contaminants. The experiments were designed to determine the solubility of the mineral chromite in...

Colombian emeralds – internal and external growth and dissolution features

Franz, Gerhard | Schiperski, Ferry | Khomenko, Vladimir | Gernert, Ulrich | Nissen, Jörg

2025

Emeralds from Colombia are among the most highly-prized and valuable gemstones. Their growth phenomena including information about the geology of the area were described in detail by Pig-natelli et al. (2015, 2022) and Schmetzer and Martayan (2023). Here, we present data obtained by scanning...

Balestrieri, Maria Laura | Olivetti, Valerio | Chew, David | Zurli, Luca | Zattin, Massimiliano | Drakou, Foteini | Cornamusini, Gianluca | Perotti, Matteo

2023

This dataset contains provenance detrital data from the glacimarine sequence of Deep Sea Drilling Project Leg 28, Site 271 e 272. The two boreholes are located in the middle of the Ross Sea, in a key site close at 180° longitude that is considered the present confluence between ice flows fed by...

Geochemical and isotopic compositions of minerals and bulk rocks of the Chachimbiro Volcanic Complex (Northern Andes, Ecuador)

Chiaradia, Massimo | Bellver Baca, Maria Teresa | Ulyanov, Alexey

2025

This dataset provides geochemical data from from the Quaternary Chachimbiro Volcanic Complex (CVC), situated in the Western Cordillera of Ecuador, Northern Andes (0.468°N, 78.287°W). The CVC is subdivided into 4 eruptive stages (CH1, CH2, CH3, CH4) ranging in age between ~400 and ~4 ka ago...
