Oxygen isotope thermometry and composition of aqueous fluids within the parent body of asteroid (101955) Bennu

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2567-2591, October 2026.
Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...

Pyroxene Spectroscopy: Effects of Major Element Composition on Near, Mid and Far-Infrared Spectra

, 2005
Pyroxene is one of the most common minerals in both evolved and undifferentiated solid bodies of the solar system. Various compositions of pyroxene have been directly studied in meteorites and lunar samples and remotely observed by telescopic and orbital

The iron isotope composition of pyroxene from the Skaergaard layered mafic intrusion, East Greenland

, 2019
Iron isotopes show small fractionations in igneous rocks emplaced at high temperature, but the processes by which these fractionations originate are still debated.

Ti solubility in diopsidic pyroxene from a suite of New South Wales leucitites (Australia)

, 1989
The pyroxene chemistry from a suite of leucitites and related differentiates from New South Wales has been investigated with the aim of understanding the physico-chemical factors which may influence the Ti solubility in the pyroxene, relative to the ...
