Thermochemical stability of low-iron, manganese-enriched olivine in astrophysical environments [PDF]
, 2012 Low-iron, manganese-enriched (LIME) olivine grains are found in cometary samples returned by the Stardust mission from comet 81P/Wild 2. Similar grains are found in primitive meteoritic clasts and unequilibrated meteorite matrix.

Olivine on Vesta as exogenous contaminants brought by impacts: Constraints from modeling Vesta's collisional history and from impact simulations [PDF]
, 2016 The survival of asteroid Vesta during the violent early history of the Solar System is a pivotal constraint on theories of planetary formation. Particularly important from this perspective is the amount of olivine excavated from the vestan mantle by ...

The problematically short superwind of OH/IR stars - Probing the outflow with the 69 {\mu}m spectral band of forsterite [PDF]
, 2013 Spectra of OH/IR stars show prominent spectral bands of crystalline olivine (Mg$_{(2-2x)}$Fe$_{(2x)}$SiO$_{4}$). To learn more about the timescale of the outflows of OH/IR stars, we study the spectral band of crystalline olivine at 69 {\mu}m. The 69 {\mu}

Multiscale modeling of upper mantle plasticity: From single-crystal rheology to multiphase aggregate deformation [PDF]
, 2014 We report a first application of an improved second-order (SO) viscoplastic self-consistent model for multiphase aggregates, applied to an olivine + diopside aggregate as analogue for a dry upper mantle peridotite deformed at 10 15 s 1 shear strain rate ...

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 SciencesOlivine 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.

Oxygen isotope geochemistry of the second HSDP core [PDF]
, 2003 Oxygen isotope ratios were measured in olivine phenocrysts (~1 mm diameter), olivine microphenocrysts (generally ~100–200 µm diameter), glass, and/or matrix from 89 samples collected from depths down to 3079.7 m in the second, and main, HSDP core (HSDP-2)
