Oxygen Isotopes of Al-rich Chondrules from Unequilibrated Ordinary Chondrites
Al-rich chondrules (ARCs) are a rare constituent of chondrites. They have relatively high bulk Al20 3 content(> 10 wt%), which is due to the presence of Al-rich phases, such as plagioclase, spinel, Al-rich glass etc. [1]. ARCs share some chemical and petrologic characteristics with Ca, Al-rich inclusions (CAis), and may represent a genetic link between ferromagnesian chondrules and CAis. Twelve...
متن کاملCryptic Metamorphic Effects in Chondrules from Highly Unequilibrated Ordinary Chondrites: an Insidious Parent-body Process
Introduction: Type 3 ordinary chondrites display a wide variety of metamorphic grades, ranging from little metamorphosed type-3.0 chondrites up to nearly equilibrated type 3.9's. Researchers commonly assume that pristine-looking chondrules found in the lowest petrological subtypes have been unaffected by metamorphic processes, and can be used to constrain pre-accretionary processes. Last year, ...
متن کاملOrigins of Chondrules in the Metal-rich Carbonaceous Chondrites
Introduction: The metal-rich CH and CB chondrites are among the most primitive (unmetamorphosed, unaltered), but controversial meteorites: both nebular and asteroidal models have been proposed to explain the origins of their components [1-14]. In addition to porphyritic chondrules and rare refractory inclusions, the CHs contain a high abunbance (~20 vol%) of metal and dominant cryptocrystalline...
متن کاملOxygen isotopes in calcium^aluminum-rich inclusions from enstatite chondrites: new evidence for a single CAI source in the solar nebula
Calcium^aluminum-rich inclusions (CAIs) from enstatite chondrites have large 16O excesses, similar to CAIs in carbonaceous and ordinary chondrites, and are also similar in morphology, mineralogy and Al^Mg isotopic systematics. These similarities provide new evidence that most CAIs might have formed in a single, restricted nebular locale and were then distributed unevenly throughout the various ...
