Cl, Al AND OXYGEN ISOTOPES IN AN ALLENDE CAI: IMPLICATIONS FOR SECONDARY ALTERATION IN THE EARLY SOLAR
نویسندگان
چکیده
Introduction: Ca-Al-rich inclusions (CAIs) from Allende usually have secondary alteration phases such as anorthite, grossular, sodalite, and nepheline [1-3]. Although these phases are considered to have been formed by relatively low temperature reactions between CAIs and a surrounding nebular gas [1, 2], it is not well known that when such processes occurred. 36 Cl-36 S and

Rare Earth Elements and Oxygen Isotopes in Allende Chondrules as Evidence for Cai Mixing in Chondrule Precursors
Introduction: The relationship between calcium-alumnium-rich inclusions (CAIs) and chondrules remains poorly constrained. CAIs appear to be older than chondrules, as inferred from a higher initial 26 Al/ 27 Al in the former; a chronological interpretation of this difference leads to an age gap of ca.1-2Myr between the formation of CAIs and that of chondrules. However this chronological interpre...
متن کاملOxygen Isotope Measurements of a Rare Murchison Type a Cai and Its Rim
Introduction: Ca-, Al-rich inclusions (CAIs) from CV chondrites commonly show oxygen isotope heterogeneity among different mineral phases within individual inclusions reflecting the complex history of CAIs in both the solar nebula and/or parent bodies [1]. The degree of isotopic exchange is typically mineralspecific, yielding O-rich spinel, hibonite and pyroxene and O-depleted melilite and anor...
متن کاملRevisiting the Cai Oxygen Isotope Anomaly
Motivation: Mass-independently fractionated oxygen isotopes in CAI [1] are widely assumed to be due to self-shielding (hereafter SS) of CO in early solar environments [e.g. 2]. However, the SS process necessarily leads to an unusual prediction that a mean solar oxygen isotopic composition differs from most of planetary bodies, but is close to a typical CAI oxygen. The latest results of the Gene...

Introduction: The refractory Calcium-Aluminumrich Inclusions (CAIs) preserve petrographic and geochemical records of the earliest events that shaped our Solar System. Absolute high-resolution Pb-Pb dating of CAIs has revealed them to be the oldest solids in the Solar System [1-4]. Another useful high-resolution relative dating technique is the Al-Mg short-lived chronometer which has been used e...

ERINGAITE-BEARING ULTRA-REFRACTORY CAI A. N. Krot, K. Nagashima, C. Ma, G. J. Wasserburg. HIGP, U. Hawai‘, USA. CalTech, USA. Introduction: Forsterite-bearing Type B (FoB) Ca,Al-rich inclusions (CAIs) are a rare type of coarse-grained igneous CAIs found almost exclusively in CV3 chondrites [1–5]. Here we describe the mineralogy, petrography, and oxygen-isotope compositions of a FoB CAI Al-2 fro...
