CHEMICAL CLASSIFICATION OF IRON METEORITES: XII. NEW MEMBERS OF THE MAGMATIC GROUPS - A NEWLY IDENTIFIED PYROXENE-BEARING PALLASITE

Wasson J.T.; Choi B.G.; Jerde E.A.; Ulff-Moller F. (1998)

Data are reported for thirty iron meteorites that are members of the magmatic groups, for three main group pallasites, one anomalous mesosiderite, and for three ungrouped irons and an ungrouped pallasite that are similar ...
MAGMATIC ACTIVITY ON THE IVA PARENT BODY: EVIDENCE FROM SILICATE-BEARING IRON METEORITES

Ulff-Moller F.; Rasmussen K.L.; Prinz M.; Palme H.; Spettel B.; Kallemeyn G.W. (1995)

Four of the magmatic IVA iron meteorites contain tridymite or clinobronzite-orthobronzitetridymite which are quite unlike silicate assemblages in other iron meteorites. The textures, the bulk chemistry, and the zoning ...
MASSIVE CHROMITE IN THE BRENHAM PALLASITE AND THE FRACTIONATION OF CR DURING THE CRYSTALLIZATION OF ASTEROIDAL CORES

Wasson J.T.; Lange D.E.; Francis C.A.; Ulff-Moller F. (1999)

Large (=<2 mm) chromite grains are present in IIIAB iron meteorites and in the main-group pallasites (pmg), closely related to high-Au IIIAB irons. Pallasites seem to have formed by the intrusion of a highly evolved metallic ...
THE PORTALES VALLEY METEORITE BRECCIA: EVIDENCE FOR IMPACT-INDUCED MELTING AND METAMORPHISM OF AN ORDINARY CHONDRITE

Rubin A.E.; Ulff-Moller F.; Wasson J.T.; Carlson W.D. (2001)

The Portales Valley H-chondrite fall is an annealed impact-melt breccia with coarse metal interstitial to angular and subrounded silicate clasts. The large metal-rich regions exhibit a Widmanstatten structure and contain ...
THE THERMAL EVOLUTION OF IVA IRON METEORITES: EVIDENCE FROM METALLOGRAPHIC COOLING RATES

Rasmussen K.L.; Ulff-Moller F.; Haack H. (1995)

Metallographic cooling rates of group IVA iron meteorites have been recalculated based on the most recent Ni diffusion coefficients and phase diagram. The cooling rates are revised upwards by a factor of ca. 15 relative ...
