- Olivine Ni isotopes of Ni-Cu deposits in northwest China: A potential . . .
A set of olivine from sulfide-barren and sulfide-bearing rocks, coupled with numerical modeling, was analyzed to (1) better understand Ni isotopic behavior during key processes in the formation of magmatic Ni-Cu deposits, such as postcumulus re-equilibration (diffusion modification), sulfide segregation, and magma replenishment, and (2
- Olivine - an overview | ScienceDirect Topics
Introduction Olivine is an important rock-forming mineral and is common in mafic igneous rocks such as peridotite, gabbro, and basalt, along with pyroxene and plagioclase The ultramafic rock dunite consists almost entirely of olivine, and is the result of the fractional crystallization of peridotite-composition melts to form cumulate olivine
- Olivine formation processes and fluid pathways in subducted . . .
These data are used to distinguish in-situ olivine and fluid production during the antigorite+brucite reaction from fluid migration and olivine crystallization during reactive fluid flow
- Trace elements in olivine: Proxies for petrogenesis, mineralization and . . .
Olivine is a ubiquitous mineral in mafic-ultramafic rocks and has been widely used as a mineral marker in various geological processes However, its d…
- Kinetics and mechanism of mineral carbonation of olivine for CO2 . . .
Mineral carbonation (MC) is one of the most important methods to sequester CO2 due to the advantages of permanently storage and abundant mineral resou…

Lithium (Li) concentration and Li isotopes of olivine have been widely adopted to decipher the mantle-crust interaction and short-lived magmatic proce…
- Geochemistry of pallasite olivine and the origin of pallasites
Olivine is the dominant non-metallic phase and the proto-pallasite mantle was composed of roughly cm-sized olivine with minor chromite formed either as magma-ocean cumulates or restites
