Aqueous alteration of chondrules from the Murchison CM carbonaceous chondrite: Replacement, pore filling, and the genesis of polyhedral serpentine
Forsterite and clinoenstatite in type IAB chondrules from the Murchison CM carbonaceous chondrite have been partially serpentinized, and the mechanisms of their alteration reveal crystallographic and microstructural controls on the reaction of silicate minerals with parent body aqueous solutions. Grains of forsterite were altered in two stages. Narrow veinlets of Fe-rich serpentine formed first...
متن کاملMagnesium Isotope Compositions of Chondrules from the Murchison and Murray Carbonaceous Chondrites
Introduction: High-precision Mg isotope compositions of meteorites and their components can provide unique constraints on the time scales and processes involved in their formation [1]. Since the advent of multicollector inductively coupled plasma mass spectrometry (MC-ICPMS), there have been several reports of high-precision analyses of the mass-dependent fractionation of Mg isotopes in chondru...
متن کاملPristine Pre-accretionary Signatures in Cm Chondrite Silicates: a Common Parent-body with the Co Chondrites?
Introduction: The Mighei-like carbonaceous (CM) chondrites are one of the most abundant and aqueously altered group of carbonaceous chondrites [1–4]. The organic molecules present and the effects of aqueous alteration have been extensively studied in the CM chondrites [e.g., 1,3,5]. As many CM chondrites are extensively aqueously altered, the compositions and formation histories of their anhydr...
متن کاملThe paradox between low shock-stage and evidence for compaction in CM carbonaceous chondrites explained by multiple low-intensity impacts
Petrographic analysis of eight CM carbonaceous chondrites (EET 96029, LAP 031166, LON 94101, MET 01072, Murchison, Murray, SCO 06043, QUE 93005) by electron imaging and diffraction, and X-ray computed tomography, reveals that six of them have a petrofabric defined by shock flattened chondrules. With the exception of Murchison, those CMs that have a strong petrofabric also contain open or minera...
متن کاملBulk Compositions and Petrographic Characteristics of Ten Unusual Carbonaceous Chondrites
We used INAA to determine the bulk compositions of 10 carbonaceous chondrites of uncertain classification. Most samples were analyzed in duplicates and the averaged results are given in Table 1 and shown in Figs. 1 and 2. Thin sections were examined microscopically. Mgand Cr-normalized abundance patterns show clear identifications for four specimens (Fig. 1. The others have nonindicative elemen...
