Data supplement to: Laser ablation in situ silicon stable isotope analysis of phytoliths

Frick, Daniel A. | Schuessler, Jan A. | Sommer, Michael | von Blanckenburg, Friedhelm

2018

Silicon is a beneficial element for many plants, and is deposited in plant tissue as amorphous bio-opal (phytoliths). The biochemical processes of uptake and precipitation induce isotope fractionation: the mass-dependent shift in the relative abundances of the stable isotopes of silicon. At the...

Mineral reflectance spectra and chemistry of 29 rare earth-bearing minerals and rare earth oxide powders including niobium- and tantalum-oxide powder

Koerting, Friederike | Koerting, Friederike | Boesche, Nina Kristin | Rogass, Christian | Mielke, Christian | Koellner, Nicole | Altenberger, Uwe

2019

The data set contains mineral chemical analyses of 32 rare earth element (REE) -bearing minerals (REMin) and rare-earth oxides (REO) and their corresponding hyperspectral spectra. The hyperspectral data was acquired with the HySpex system in a range of 400 – 2500 nm and is presented in a...

Composite OSG Logging Data from the PTA-2 borehole, Big Island, Hawai'i

Kueck, Jochem

2019

Compilation of downhole logging data from the borehole PTA2 inside Bradshaw Army Camp in the saddle region between Mauna Kea and Mauna Loa on the Big Island of Hawai'i (Composite OSG Logging Data Hawaii PTA2.asc, ASCII). The PTA2 borehole was fully cored into a lava dominated rock sequence;...

Database of mineral compositions within the lower oceanic crust from the ultraslow-spreading Gakkel Ridge

Scarani, Sarah | Basch, Valentin | Genske, Felix | Böhnke, Mischa | Berndt, Jasper | Stracke, Andreas | Sanfilippo, Alessio

2026

This database contains mineral major and trace element compositions of gabbroic rocks composing the lower oceanic crust from the ultraslow-spreading Gakkel Ridge. The lithological suite analysed in this research was recovered during the Artic Mid-Ocean Ridge Expedition (AMORE 2001) with the...

Halogen (F, Cl, Br, I) compositions of minerals and whole-rocks from cryolite-bearing granitic systems

Zhu, Yuxiang | Wang, Lianxun | Girei, Musa Bala | Pan, Yuanming | She, Zhen-Bing | Zhang, Chao | He, Tao | Marks, Michael A.W.

2026

This dataset provides a comprehensive, multi-scale geochemical and mineralogical archive from the Ririwai cryolite-bearing granitic complex, systematically documenting halogen (F, Cl, Br, I) behavior and rare-metal enrichment signatures during magmatic-hydrothermal evolution. The data scope...

Comprehensive dataset for the Hujialin ultramafic body in the Sulu orogen: Mineral proportions, whole-rock geochemistry, Sr-Nd-O isotopes, mineral chemistry, and melt/cumulate modeling

Wang, Chuang | Chen, Ren-Xu | Zhang, Nian-Qin | Yin, Zhuang-Zhuang | Gong, Bing | Zha, Xiang-Ping | Sun, Guo-Chao

2026

This dataset presents a comprehensive geochemical and petrological record for the Hujialin ultramafic body in the Sulu orogenic belt, a major ultrahigh-pressure terrane in eastern China. The data compilation includes mineral proportions (Table S1), whole-rock major and trace element...

Results from analogue inversion experiments of extensional basins parallel and oblique to their boundaries with inferences from the European eastern Southern Alps

Sieberer, Anna-Katharina | Willingshofer, Ernst | Klotz, Thomas | Ortner, Hugo | Pomella, Hannah

2026

This image dataset contains results (original top-view and cross-section photographs) obtained from a series of 12 crustal-scale physical analogue modelling experiments performed in the Tectonic Modelling Laboratory (TecLab) at Utrecht University. We employed analogue modelling to study the...

Global dataset for combined mineral major and trace element data for rocks from the lower oceanic crust

Scarani, Sarah | Basch, Valentin | Genske, Felix | Böhnke, Mischa | Berndt, Jasper | Zanetti, Alberto | Stracke, Andreas | Sanfilippo, Alessio

2026

This work presents a Global dataset for combined mineral major and trace element data for rocks from the lower oceanic crust sampled along mid-ocean ridges worldwide. The dataset compiles mineralogical and geochemical data obtained from samples recovered along mid-ocean ridges characterized...

SEM and EPMA data of minerals from Jacupiranga carbonatite, Brazil

Abudayeh, Ahmad | Arato, Robert | Vetlényi, Enikő | Guzmics, Tibor

2026

The Jacupiranga carbonatite (Brazil) was investigated to better understand how modal proportions and mineral chemistry control the fO2 recorded by a natural carbonatite rock. Mineral compositions were determined using SEM-EDS, EPMA-WDS and Raman microspectroscopy building upon detailed...

Geochemistry and petrology of black opal in the pegmatites from Volyn (Ukraine)

Franz, Gerhard | Schiperski, Ferry | Khomenko, Vladimir | Gernert, Ulrich | Nissen, Jörg | Chornousenko, Vsevolod | Zeh, Armin

2026

Black opal is a rare variety of opal-CT, which is pigmented by organic matter (OM) and can therefore be considered as an example of geo-bio interaction (Gouzy et al., 2025). The locality of Volyn, Ukraine with its famous chamber pegmatites is well-known for interaction between OM and igneous...
