2003年9月1日 · Gujba is a coarse-grained meteorite fall composed of 41 vol% large kamacite globules, 20 vol% large light-colored silicate globules with cryptocrystalline, barred pyroxene and barred olivine textures, 39 vol% dark-colored, silicate-rich matrix, and rare refractory inclusions.

2022年9月1日 · As such, we propose a two-stage model to explain the formation of chondrules in Gujba, with Stage 1 characterized by incomplete condensation of vaporized material with an average isotopic fractionation factor (α) of 0.9984 (when using the most K enriched chondrule to constrain the model), and Stage 2 representing partial evaporation in a vapor p...

The Gujba, Nigeria meteorite is the first ob-served fall (3 April 1984) of a Bencubbin-like meteorite [1]. Gujba texturally resembles Ben-cubbin and QUE94411 except that, in Gujba, the coarse metal and silicate nodules are round and generally unfragmented. The compositions of the metal and silicates in Gujba are similar to

2002年3月1日 · Here we present the preliminary results of our petrologic study of Gujba, a new metal-rich CB chondrite that is petrologically and oxygen isotopically similar to Bencubbin and Weatherford, and is the only CB fall [9].
