Mineral Chemistry Olivine and serpentine actually represent two distinct mineral groups. Olivine includes the solid solution series between magnesium-rich (forsterite) and iron-rich (fayalite) end members. Forsterite is by the far the most abundant olivine mineral in nature, though some Fe in substitution for Mg is always present.
Here we present results from laboratory flow-through dissolution experiments which seek to bridge this observational discrepancy by using columns of soil returned to the laboratory from a field site. ... Neil Rowson (University of Birmingham) is thanked for his help with olivine comminution. Phil Holdship, Steve Wyatt (University of Oxford) and ...
Here, we propose a novel approach to directly measuring dislocation mobility in olivine at room temperature, hence providing a very efficient lever arm effect to anchor rheological laws (see Fig. 1).

Nanocrystals also can be the direct product of comminution rather than phase transformation 40,41, but to our knowledge comminution has not been shown to yield a fully dense nanometric solid that ...
The Jurassic Pineto ophiolite from Corsica exposes a ~1-km-thick troctolite–olivine-gabbro sequence, interpreted to represent a lowermost sector of the gabbroic oceanic crust from a (ultra-)slow spreading system. To constrain the petrogenesis of the olivine-gabbros, minor and trace element analyses of olivine (forsterite = 84–82 mol%) were carried …
However, olivine NaFePO 4 only can be synthesized from olivine LiFePO 4. Accordingly, in this proposal, developing the continuous flow electrochemical solid-liquid reactor-based metal ion insertion technology is to utilize the olivine FePO 4, recycled from LiFePO 4, and to synthesize NaFePO 4.
This paper investigates how mechanical activation of olivine can increase the minerals surface reactivity, and illustrates how such technology can give rise to new or improved olivine …
Olivine was added to a soil column experiment to test the enhanced weathering carbon sequestration. Dissolution rates were found to be between 10 −16.4 and 10 −15.5 …

To provide an upper bound on the grain size of the dehydration products that may have caused strain weakening in our experiments, we use a flow law for diffusion creep of wet olivine (Hirth and...
The mechanism of the mechanically assisted mineral carbonation of commercial olivine under the flow of a carbon dioxide (CO 2)/nitrogen (N 2) mixture has been elucidated …
The work presents a theoretical and experimental assessment of the mechanical power absorption by a prototype horizontal ring mill, during the continuous comminution of olivine with feed rates for ...
Finally, a clear path to meet your climate action and sustainability goals. From innovative R&D that unlocks critical advances to next-generation software and expertise – Olivine has the resources, tools and relationships to accelerate the transformation to …
Saline water (0.5 m NaCl) was continuously injected into olivine powder at a constant flow rate (3.3 × 10 −5 L s −1). Petrologic observation of solid products after experimental runs revealed that serpentine is produced from olivine. The hydration flux of serpentinization in this experiment is similar to estimates made using closed-system ...

The AG-type and the B-type olivine fabrics in natural cumulates can be interpreted as results of anisotropic growth of olivine and viscous magmatic flow. Anisotropic olivine growth is expected to ...
Molecular hydrogen (H 2) may be an important form of water in nominally anhydrous minerals in the Earth's mantle and plays a critical role in mantle water cycle, but the transport properties of H 2 remain unclear. Here, the diffusion of H 2 in Fe-free olivine lattice is investigated at pressures of 1–13 GPa and temperatures of 1300–1900 K by first-principles …

At project scale, Oregon-sourced olivine-bearing fines achieve approximately 52,000 to 65,800 net t CO 2 e sequestration. If a local source of olivine-bearing rock was established, even with comminution, net sequestration could increase to 72,200 net t CO 2 e. Approximately 15 years would be required to completely weather each of the 6 field ...
