Volume 1. David Alderton, in Encyclopedia of Geology (Second Edition), 2021. 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 …
The common occurrence of spinel inclusions in primitive olivine hosts indicates that spinel and olivine co-saturate early in many locations (e.g., Coogan et al., 2014; Matthews et al., 2016; Spice et al., 2016; Trela et al., 2017), and the close spatial relationship suggests the phases were in equilibrium with the same melt (and, therefore ...

A coesite-bearing diamondiferous eclogite from the Udachnaya kimberlite (Daldyn field, Siberian craton) has been studied to trace its complex evolution recorded in rock-forming and minor mineral constituents. The eclogite sample is composed of rock-forming omphacite (60 vol%), garnet (35 vol%) and quartz/coesite (5 vol%) and …
Figure 3. BSE images of experimental olivine at different times and temperatures showing processes of growth and ripening. Panels (A,C,G) and (B,D,H) display shorter and longer experimental durations for each undercooling, respectively. Sections elongated along the c-axis in panels (C,D,G,H) are commonly observed in 2D. However, 3D scans reveal that …

Olivine - Mineralogy, Mg-Fe, Silicates: The specific gravity and hardness of the olivines are listed in the Table. There are at least two cleavages—i.e., the tendency to split along preferred crystallographic directions (perpendicular to the a and b axes in this case)—both of which are better-developed in the iron-rich varieties. Forsterite contained in certain …

Fe-rich olivine could be an important constituent of the mantles of oxidized terrestrial planets. Although olivine in the Earth's uppermost mantle is considered to have Mg# = Mg/(Mg + Fe 2+) = 0.9, olivine in the Martian mantle likely has Mg# = 0.75 (Khan et al. 2018).The composition of more distant terrestrial planets can be estimated from the …

Jezero crater, the landing site of the Perseverance rover, is located at the western edge of Isidis Planitia on Mars ().Orbital data have constrained the crater's age to between 3.82 billion and 3.96 billion years (1, 2).A light-toned, olivine- and carbonate-bearing rock unit exposed on the floor of Jezero has been informally named the Séítah formation (3–5).
The Tier 1 Argyle diamond mine is a large (47 ha, Table 2) steep sided and elongated olivine lamproite pipe that is interpreted to have formed from several distinct individual diatremes that have coalesced, and are aligned along a fault (Rayner et al. 2018a,b; Fig. 8), with the fault presumably coincident with an olivine lamproite feeder dike.

Olivine's best known economic use is the gemstone peridot (pronounced pair-a-doe), often used as a birthstone for August. Peridot has a pale yellow-green color and is sometimes called evening emerald or even mistakenly as chrysolite in the jewelry trade.Although relatively soft for a gemstone, peridot's beauty allows it to compete with harder …

H 2 O-dependent thermometers [e.g., Mg partitioning between olivine and melt – Ford et al. (1983)] will give higher temperatures than H 2 O-independent thermometers [e.g., Al-in-olivine – Wan et al.
