CHARACTERIZATION OF TRACE ND AND CE SITE PREFERENCE AND COORDINATION IN NATURAL MELANITES: A COMBINED X-RAY DIFFRACTION AND HIGH-ENERGY XAFS STUDY

Quartieri S.; Boscherini F.; Chaboy J.; Dalconi M.C.; Oberti R.; Zanetti A. (2002)

Natural melanite garnets from carbonatitic rocks have been studied by a multitechnique approach based on both experimental (chemical, diffractometric and spectroscopic) methods and full-multiple scattering calculations of ...
DISTINCT SITE PREFERENCES FOR HEAVY AND LIGHT REE IN AMPHIBOLE AND THE PREDICTION OF AMPH/LDREE

Bottazzi P.; Tiepolo M.; Vannucci R.; Zanetti A.; Brumm R.; Foley S.F.; Oberti R. (1999)

New experimental amphibole/melt partition coefficients from a variety of geologically relevant amphibole (pargasite, kaersutite, and K-richterite) and melt compositions obtained under conditions of interest to upper-mantle ...
INFILTRATION METASOMATISM AT LHERZ AS MONITORED BY SYSTEMATIC ION-MICROPROBE INVESTIGATIONS CLOSE TO A HORNBLENDITE VEIN

Zanetti A.; Vannucci R.; Bottazzi P.; Oberti R.; Ottolini L. (1996)

Systematic investigations (electron- and ion-microprobe, and X-ray structure-refinement) of pyroxenes and amphiboles close to a cm-wide hornblendite vein have been carried out on a composite peridotite sample from the Lherz ...
MECHANISMS AND SOURCES OF MANTLE METASOMATISM: MAJOR AND TRACE ELEMENT COMPOSITIONS OF PERIDOTITE XENOLITHS FROM SPITSBERGEN IN THE CONTEXT OF NUMERICAL MODELLING

Ionov D.A.; Bodinier J.-L.; Mukasa S.B.; Zanetti A. (2002)

Mineral and whole-rock chemical data for peridotite xenoliths in basaltic lavas on Spitsbergen are examined to reassess mechanisms of melt–fluid interaction with peridotites and their relative role versus melt composition ...
MINERAL CHEMISTRY OF ULTRAMAFIC MASSIFS IN THE SOUTHERN URALIDES OROGENIC BELT (RUSSIA) AND THE PETROGENESIS OF THE LOWER PALAEOZOIC OPHIOLITES OF THE URALIAN OCEAN

Spadea P.; Zanetti A.; Vannucci R. (2004)

Ophiolites of the southern Uralides arc-continent collisional orogen include fertile mantle lherzolites and minor harzburgites in the Nurali and Mindyak massifs located along the Main Uralian Fault suture of the East ...
NB AND TA INCORPORATION AND FRACTIONATION IN TITANIAN PARGASITE AND KAERSUTITE: CRYSTAL-CHEMICAL CONSTRAINTS AND IMPLICATIONS FOR NATURAL SYSTEMS

Tiepolo M.; Vannucci R.; Oberti R.; Bottazzi P.; Zanetti A.; Foley S. (2000)

New partition coefficients between liquid and pargasitic/kaersutitic amphiboles (Amph/LDNb,Ta) experimentally determined for Nb and Ta at upper-mantle conditions, combined with single-crystal structure refinement of the ...
TRACE-ELEMENT PARTITIONING IN OLIVINE: MODELLING OF A COMPLETE DATA SET FROM A SYNTHETIC HYDROUS BASANITE MELT

Zanetti A.; Tiepolo M.; Oberti R.; Vannucci R. (2004)

Olivine/liquid partition coefficients for most trace elements relevant in petrogenetic studies are provided for a hydrous basanite melt equilibrated at 1.4 GPa and 1055 °C. The partitioning results determined by a combination ...
