Olivine weathering in soil, and its effects on growth and nutrient uptake in Ryegrass (Lolium perenne L.): a pot experiment. [PDF]
PLoS ONE, 2012 Mineral carbonation of basic silicate minerals regulates atmospheric CO(2) on geological time scales by locking up carbon. Mining and spreading onto the earth's surface of fast-weathering silicates, such as olivine, has been proposed to speed up this ...

Trace element geochemistry of ordinary chondrite chondrules: the type I/type II chondrule dichotomy [PDF]
, 2015 We report trace element concentrations of silicate phases in chondrules from LL3 ordinary chondrites Bishunpur and Semarkona. Results are similar to previously reported data for carbonaceous chondrites, with rare earth element (REE) concentrations ...

Analyzing the Magnesium (Mg) Number of Olivine on the Lunar Surface and Its Geological Significance
Remote Sensing, 2019 Olivine formation is directly related to Mg/Fe content. It is also significant in estimating the geological evolution of the moon. In this study, an estimation model of relative Mg number (Fo#) for lunar olivine was presented through multiple linear ...

西南日本の熱変成超苦鉄質岩体中のかんらん石と輝石の組成変化に関する覚書 [PDF]
, 2010 This short article presents some diagrams showing the compositional variations of primary and metamorphic olivine, orthopyroxene and clinopyroxene in peridotites and serpentinites from thermally metamorphosed ultramafic complexes in SW Japan. In contrast

Extrinsic and intrinsic strength of amorphous olivine films [PDF]
European Journal of MineralogyNanoscale 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.
