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...

Analytical, modelled, and imaging data of eclogitic clinopyroxene inclusions hosted in diamonds from the Cullinan Mine (South Africa) and the Rassolnaya Placer (Urals Mountains, Russia)

Wang, Wenyu | Korolev, Nester M. | Kiseeva, Ekaterina S. | Davies, Rondi M. | Weiss, Yaakov | Kopylova, Maya | Towbin, W. Henry | Huang, Fang | Moore, Andy E. | Vasilev, Evgeniy A.

2025

This dataset comprises analytical, modelled, and imaging data of eclogitic clinopyroxene inclusions hosted in diamonds from the Cullinan Mine (South Africa) and the Rassolnaya Placer (Urals Mountains, Russia). Six inclusions containing varying proportions of spongy clinopyroxene (~10–100%) were...

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...

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...

In-situ Raman spectra from Na2ATP solutions with starting pH 3 and 7 at 80,100 and 120 °C for determination of the hydrolysis rate constant of ATP

Moeller, Christoph | Schmidt, Christian | Guyot, François | Wilke, Max

2024

Extremophiles maintain an active metabolism up to 122 °C (Takai et al. 2008). These extreme conditions are found, for example in hot springs, in deep oceanic and crustal sediments and in hydrothermal vents at mid-oceanic spreading ridges (Edwards et al., 2011; Heuer et al., 2020). Several...

Database of in-situ Raman spectra from Na2H2ATP solutions at 80,100 and 120 °C and up to 1666 MPa for determination of the rate constant of the ATP hydrolysis

Moeller, Christoph | Schmidt, Christian | Testemale, Denis | Guyot, François | Kokh, Maria A. | Wilke, Max

2023

In biochemical systems, enzymes catalyze the endergonic phosphorylation of adenosine diphos-phate (ADP) to adenosine triphosphate (ATP) by different pathways, e.g., oxidative phosphoryla-tion catalyzed by membrane bound ATP synthase or substrate-level phosphorylation. The stored energy is...

Orientation data of lineations and foliations from the central Tauern Window (Austria)

Groß, Philip

2024

This dataset contains orientation data for foliations (n=773) and lineations (n=512) from the central Tauern Window collected during fieldwork in the years 2016 to 2019. The data is distributed in the form of shapefiles for easy use with GIS software. It can be displayed conveniently using...

Agostini, Samuele | Leone, Noemi | Smellie, John L. | Rocchi, Sergio

2024

This dataset presents a set of geographical, geochemical and isotopic data, microphotos of thin sections and geochemical binary variation diagrams of sixteen samples of volcanic rocks collected in The Pleiades Volcanic Field, Northern Victoria Land, Antarctica (≈ 72° 42’ S; 165° 43’ E), made up...

GlobaLID – Global Lead Isotope Database (Version 12/2023)
