Oxygen Thermobarometry of Orogenic Lherzolite Massifs

open access: yesJournal of Petrology, 1992
The oxidation state has been determined for spinel peridotites from 13 orogenic lherzolite massifs including Beni Bousera, Ronda, and 11 smaller massifs in the French Pyrenees. The oxygen fugacity (f o2) was calculated for 67 samples from microprobe analyses using a set of secondary spinel standards to correct the ferric iron content in the spinels ...

Using the elastic properties of zircon-garnet host-inclusion pairs for thermobarometry of the ultrahigh-pressure Dora-Maira whiteschists: problems and perspectives [PDF]

open access: yes, 2021
The ultrahigh-pressure (UHP) whiteschists of the Brossasco-Isasca unit (Dora-Maira Massif, Western Alps) provide a natural laboratory in which to compare results from classical pressure (P)–temperature (T) determinations through thermodynamic modelling ...
