Nonporphyritic chondrules from equilibrated Rumuruti and ordinary chondrites: Chemical evidence of secondary processing
(Meteoritical Soc, 2012-08)
Nineteen nonporphyritic pyroxene and pyroxene/olivine chondrules, chondrule fragments, and irregular objects were studied from two equilibrated chondrites, the ordinary (L/LL5) Knyahinya chondrite and the Rumuruti type ...

Room temperature 57Fe Mössbauer spectroscopy of ordinary chondrites from the Atacama Desert (Chile): constraining the weathering processes on desert meteorites
(Springer Netherlands, 2008-04)
We report the results of a study on the weathering products of 21 meteorites
found in the Atacama Desert (Chile) using room temperature 57Fe Mössbauer spectroscopy
(MS). The meteorites are weathered ordinary chondrites ...

The Tucson ungrouped iron meteorite and its relationship to chondrites
(Meteoritical Soc, 2010-12)
Tucson is an enigmatic ataxitic iron meteorite, an assemblage of reduced silicates embedded in Fe-Ni metal with dissolved Si and Cr. Both, silicates and metal, contain a record of formation at high temperature (∼1800 K) ...
