Monticellite is a common magmatic mineral in the groundmass of kimberlites. A new oxygen barometer for kimberlite magmas is calibrated based on the Fe content of monticellite, CaMgSiO4, in equilibrium with kimberlite liquids in experiments at 100 kPa from 1,230 to 1,350°C and at logfO2 from NNO-4.1 to NNO+5.3 (where NNO is the nickel–nickel oxide buffer). The …

The adiabatic single-crystal elastic moduli of a natural sample of monticellite (CaMgSiO 4), with the olivine crystal structure, have been measured under ambient conditions using Brillouin spectroscopy.From the single-crystal moduli the aggregate bulk and shear moduli are calculated to be K s =106±1 and μ = 55.2±0.4 GPa, respectively. These results are consistent with a …

An Adirondack marble contains the assemblage calcite-diopside-forsterite-monticellite, with trace amounts of zincian spinel, titanian andradite, idocrase, and sphalerite. Microprobe analyses indicate that the monticellite and forsterite both have Mg/(Mg+ Fe) greater than 0.9, and that monticellite is more iron-rich than coexisting forsterite.

Monticellite - CaMgSiO 4 Monticellite was discovered in 1831 and named by H.J.Brooke in honor of Teodoro Monticelli (1759-1845), Italian mineralogist and naturalist who published several works on Mount Vesuvius. The structure of monticellite is essentially the same as that of the (Mg,Fe)-olivines, with an expanded unit cell due to the ...

Abstract In this research, high-pure monticellite ceramic (CaMgSiO4) nanoparticles were synthesized via a novel sol–gel method using ethanol and chloride ions for the acceleration of polycondensation process. The gel obtained from metal alkoxide and metal salts precursors dried at 100°C; then, the dried-gel calcined at different temperatures to monitor the structural …
