Electron diffraction patterns and HR-EBSD data from laboratory deformed olivine aggregates

Wiesman, Harison S. | Wallis, David

2026

This dataset is supplemental to the paper Wiesman et al. (submitted) and contains data on the density of dislocations and their stress fields in olivine rocks deformed via laboratory experiments. The data were used to investigate how the quality of diffraction patterns obtained via electron...

Geochemical and modal proportion analysis of phase assemblages on experimental samples investigating the fluid-absent melting of metasediments

Liu, Yongchao | Schmidt, Christian | Wunder, Bernd | Günter, Christina | Li, Jiankang | Chen, Zhenyu | Wang, Fangyue | van Schijndel, Valby | Appelt, Oona | Sieber, Melanie

2026

The melting relations, phase compositions, and trace element partitioning behavior during metasediment partial melting were investigated by high pressure and temperature experiments (300 and 900 MPa, 750–950 °C). The here published dataset includes all geochemical analysis of experimental...

Geochemical (major and trace elements, isotopes), petrologic, and geochronologic (U-Pb, Ar/Ar) data of the Paleozoic-early Mesozoic Paleo-Tethys suture in the Afghan Hindu-Kush‒Pamir region

Ratschbacher, Lothar | Institut für Keramik, Feuerfest und Verbundwerkstoffe

2026

The Herat-Panjshir-Badakhshan—the Paleo-Tethys—suture zone of Afghanistan marks the vestige of the subducted Paleozoic-early Mesozoic Paleo-Tethys oceanic lithosphere. We investigate the evolution of rocks north of this suture in the Hindu Kush and Pamir of Afghanistan. Our study identifies...

3D XCT scans of 15mm gabbroic nodules from Gígöldur, Iceland

Subbaraman, Rahul | Buono, Gianmarco | Pappalardo, Lucia

2025

This dataset comprises 3D X-ray computed tomography (XCT) scans of eight rock cores (15 mm diameter) prepared from two gabbroic nodules collected at Gígöldur, Central Iceland. The scans are provided in the Tagged Image File Format (*.tif). Data were acquired using a Carl Zeiss Xradia...

Laser ablation inductively coupled mass spectrometry (LA-ICP-MS) of zircon U-Pb from a European terrane (Western Alps, Italy)

Balestro, Gianni | van Schijndel, Valby | Gattiglio, Marco | Borghi, Alessandro | Stefano, Ghignone

2025

Geochronological data allowed constraining the tectonostratigraphic evolution of a European terrane stacked in the Western Alps and consisting of a Palaeozoic basement overlain by a Mesozoic metasedimentary cover. Four samples belonging to the basement have been analyzed. They correspond to two...

GlobaLID – Global Lead Isotope Database (Version 08/2025)

Westner, Katrin J. | Rose, Thomas | Klein, Sabine | Hsu, Yiu-Kang | Becerra, María Florencia | Nezafati, Nima | Renson, Virginie | Stephens, Jay

2023

This dataset is a continuously growing collection of lead isotope reference data. Lead isotopes are an established method to reconstruct the raw material provenance of archaeological objects. They are typically applied to artefacts made of copper, lead, silver, and their alloys. However, also...

High-resolution quantitative electron microprobe analysis of garnets from Holsnøy, Norway

Hess, Benjamin | Ague, Jay | Austrheim, Håkon

2025

The island of Holsnøy is located in southwestern Norway. It is composed of metastable granulite facies lower crust that was subducted at 430 Ma when fluid infiltrated the region and reacted with large portions of the area to form eclogite facies shear zones. The eclogite facies assemblages...

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...

Laser ablation inductively coupled mass spectrometry trace element chemistry of sulfides from the Aouli Ag-Pb-Zn-(Cu) vein system (Upper Moulouya district, Morocco)

Zaid, Khadra | Bouabdellah, Mohammed | Frenzel, Max | van Schijndel, Valby | Levresse, Gilles | Idbaroud, Mohamed | Yans, Johan

2025

This data report presents the in-situ LA-ICP-MS trace element composition of sphalerite, pyrite, and chalcopyrite from the Aouli Ag-Pb-Zn-(Cu) vein system in the Upper Moulouya district, Morocco. The dataset contributes to a study focused on characterizing the element concentrations in sulfides...

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...
