Defects in olivine [PDF]

European Journal of Mineralogy, 2021
Olivine, a ferromagnesian orthosilicate, is the most abundant mineral in Earth's upper mantle and is stable down to the olivine–wadsleyite phase transition, which defines the 410 km depth mantle transition zone.

Intracrystalline melt migration in deformed olivine revealed by trace element compositions and polyphase solid inclusions [PDF]

European Journal of Mineralogy, 2021
Melt transport mechanisms have an important impact on the chemical composition of the percolated host rock and the migrating melts. Melt migration is usually assumed to occur at grain boundaries.

Features of olivine crystallization in ordinary chondrites (Saratov meteorite): geochemistry of trace and rare earth elements

Записки Горного института, 2022
The paper discusses the geochemistry of major (EPMA) and trace (SIMS) elements in olivine of porphyritic, nonporphyritic chondrules, and the matrix of equilibrated ordinary chondrite Saratov (L4).

Experimental Research on Electrical Conductivity of the Olivine-Ilmenite System at High Temperatures and High Pressures

Frontiers in Earth Science, 2022
Ilmenite is a common metallic oxide distributed in the mafic rocks from the Earth’s upper mantle, and thus the effect of ilmenite contents on the electrical structures of the Earth’s upper mantle should be investigated in detail.

Crystallization Kinetics of Basalt Glass-Ceramics Produced from Olivine Basalt Rock

Crystals, 2022
Glass-ceramics acquired from the melting of rocks have a vast application marketplace. In this study, an olivine basalt rock from Zhangjiakou in China was selected as a raw material to prepare basalt glass-ceramics, and the crystallization kinetics of ...

Evidence of Rapid Phenocryst Growth of Olivine During Ascent in Basalts From the Big Pine Volcanic Field: Application of Olivine‐Melt Thermometry and Hygrometry at the Liquidus

Geochemistry, Geophysics, Geosystems, 2020
The Quaternary Big Pine (BP) volcanic field in eastern California is notable for the occurrence of mantle xenoliths in several flows. This points to rapid ascent of basalt through the crust and precludes prolonged storage in a crustal reservoir.

Morphology and surface features of olivine in kimberlite: implications for ascent processes [PDF]

Solid Earth, 2014
Most kimberlite rocks contain large proportions of ellipsoidal-shaped xenocrystic olivine grains that are derived mainly from disaggregation of peridotite. Here, we describe the shapes, sizes and surfaces of olivine grains recovered from kimberlite lavas

Olivine Dissolution in Simulated Lung and Gastric Fluid as an Analog to the Behavior of Lunar Particulate Matter Inside the Human Respiratory and Gastrointestinal Systems

GeoHealth, 2021
With the Artemis III mission scheduled to land humans on the Moon in 2025, work must be done to understand the hazards lunar dust inhalation would pose to humans.

Spatial Pattern Investigation of Olivine on Mars using OMEGA and MOLA Remote Sensing Data: A Case Study at Valles Marineris and Nili Fossae [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Olivine is a mineral indicative of water activity in the mantle, and its presence can elucidate the petrological evolution and history of magmatic igneous rocks. In this work, we conducted a preliminary investigation into the characteristics and patterns

Formation mechanisms of ringwoodite: clues from the Martian meteorite Northwest Africa 8705

Earth, Planets and Space, 2021
Ringwoodite and wadsleyite are the high-pressure polymorphs of olivine, which are common in shocked meteorites. They are the major constituent minerals in the terrestrial mantle.
