The PANGAEA mineralogical database

open access: yesData in Brief, 2020
Future human missions to the surface of the Moon and Mars will involve scientific exploration requiring new support tools to enable rapid and high quality science decision-making. Here, we describe the PANGAEA (Planetary ANalogue Geological and Astrobiological Exercise for Astronauts) Mineralogical Database developed by ESA (European Space Agency): a ...

An ion probe study of the sulphur isotopic composition of Fe-Ni sulphides in CM carbonaceous chondrites [PDF]

open access: yes, 2004
From the Introduction: The CM chondrites have endured variable degrees of aqueous alteration [1] which has changed their original mineralogy. A detailed study of the petrology and mineralogy of the sulphides in a suite of increasingly aqueously altered ...

Chemical weathering and provenance evolution of Holocene–Recent sediments from the Western Indus Shelf, Northern Arabian Sea inferred from physical and mineralogical properties [PDF]

open access: yes, 2012
We present a multi-proxy mineral record based on X-ray diffraction and diffuse reflectance spectrophotometry analysis for two cores from the western Indus Shelf in order to reconstruct changing weathering intensities, sediment transport, and provenance ...

Decoding Variants of Pyrite, Arsenopyrite and Marcasite Using an Electron Counting Rule

open access: yesAngewandte Chemie International Edition, Accepted Article.
Pyrite, Marcasite and Arsenopyrite are of significant historical and contemporary interest. Compounds adopting these structure types are extensively studied for their crystallographic properties and potential applications in energy storage and conversion.

MICROINCLUSIONS OF PGM MINERALS IN ANCIENT GOLD PRODUCTS: OCCURRENCE, COMPOSITION, ALTERATION [PDF]

open access: yesМинералогия, 2015
The PGM microinclusions in ancient gold products from the Urals, Siberia, Azov region and Turkmenistan are compared with similar inclusions from the Middle East artifacts. Microinclusions were found in the archaeological sites, which are located close to

Composition, Mineralogy, and Porosity of Multiple Asteroid Systems from Visible and Near-infrared Spectral Data [PDF]

open access: yes, 2014
We provide a taxonomic and compositional characterization of Multiple Asteroid Systems (MASs) located in the main belt (MB) using visible and near-infrared (0.45-2.5 um) spectral data of 42 MB MASs. The mineralogical analysis is applied to determine meteorite analogs for the MASs, which, in turn, are applied to the MAS density measurements of Marchis ...

Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]

open access: yes, 2017
Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of
