Extrinsic and intrinsic strength of amorphous olivine films [PDF]

European Journal of Mineralogy
Nanoscale amorphous olivine (a-olivine) intracrystalline layers, which can form in olivine polycrystals under high stress, has the potential to influence the mechanical properties of the rock in the vicinity of the brittle–ductile transition.

The Olivine Horizon of the Layered Monchegorsk Pluton (Kola Region, Russia): Additional Magma Injection Based on Integrated Geological and Geochronological Data

Geosciences, 2023
The paper presents the first SIMS SHRIMP U-Pb data for zircon from an olivine horizon within the Nyud intrusion of the ore-bearing layered Monchegorsk pluton (Monchepluton) in the Kola Region, Russia.

Oxidation during magma mixing recorded by symplectites at Kusatsu–Shirane Volcano, Central Japan

Earth, Planets and Space, 2020
Kusatsu–Shirane Volcano is an active Quaternary andesitic-to-dacitic volcano located in the Central Japan Arc. We conducted a detailed petrological investigation of orthopyroxene (opx)–magnetite (mt) symplectites associated with olivine in the Sessho ...

Olivine avoidance behaviour by marine gastropods (Littorina littorea L.) and amphipods (Gammarus locusta L.) within the context of ocean alkalinity enhancement

Ecotoxicology and Environmental Safety
Gigaton scale atmospheric carbon dioxide (CO2) removal (CDR) is needed to keep global warming below 1.5 °C. Coastal enhanced olivine weathering is a CDR technique that could be implemented in coastal management programmes, but its CO2 sequestration ...

Generating porosity during olivine carbonation via dissolution channels and expansion cracks [PDF]

Solid Earth, 2018
The olivine carbonation reaction, in which carbon dioxide is chemically incorporated to form carbonate, is central to the emerging carbon sequestration method using ultramafic rocks.

High-Temperature Oxidation of Magnesium- and Iron-Rich Olivine under a CO₂ Atmosphere: Implications for Venus

Remote Sensing, 2023
Understanding crust–atmosphere interactions on Venus is fundamentally important to interpretations of Venus’ surface spectroscopic data. Olivine, in basaltic crust, is oxidized under a heated CO2 atmosphere.

Abundance and Partitioning of OH in a High-pressure Magmatic System: Megacrysts from the Monastery Kimberlite, South Africa [PDF]

, 2004
Concentrations of OH, and major and trace elements were determined in a suite of mantle-derived megacrysts that represent the crystallization products of a kimberlite-like magma at ~5 GPa and ~1400–1100°C.

Oxygen Isotopic Compositions of San Carlos Olivine Standard NMNH 111312–42

Applied Sciences
San Carlos olivine geostandard developed by Gene Jarosewich and co-workers at the Smithsonian Institution, named NMNH 111312–44, was the most widespread olivine geostandard used in olivine oxygen isotopic determination.

Glass in the submarine section of the HSDP2 drill core, Hilo, Hawaii [PDF]

, 2004
The Hawaii Scientific Drilling Project recovered ~3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than ~1 km were deposited below sea level and contain considerable fresh glass. We report electron

Orbital Observations Suggest Decoupled Olivine and Carbonate Enrichments in Jezero Crater

Geophysical Research Letters
It has been hypothesized that the olivine‐ and carbonate‐bearing units within Jezero crater are part of the broader olivine‐carbonate rock unit found in the Nili Fossae region.
