Oxygen isotope composition of the primitive Achondrites
Introduction: Primitive achondrites are meteorites with near-chondritic bulk compositions and nonchondritic textures [1]. They are thought to be either highly metamorphosed chondrites, or residues formed by low degrees of partial melting [1]. They thus record the conditions at the onset of asteroidal melting and form an important link between chondrites and the extensively melted achondrites (i...
متن کاملAubrites: Their origin and relationship to enstatite chondrites
All ten known aubrites (enstatite achondrites) as well as Happy Canyon and Mt. Egerton, related anomalous meteorites, have been studied in order to understand their origin and relationship to enstatite chondrites. Mineralogically, aubrites contain 75-9B% enstatite (En98.76-99.54), 1-16% plagioclase (Anl.S-B.:), O.Z-K.l^r diopside (Wo40.1-46.1). 0.3-10.07f olivine (Fo99.79-99,99), <0.l3.7% metal...
متن کاملHIGH-PRECISION SILICON ISOTOPE RATIO MEASUREMENTS OF EARTH AND ENSTATITIC METEORITES AND IMPLICATIONS FOR Si ISOTOPE FRACTIONATION DURING CORE FORMATION
Introduction: Core formation processes in planets may impart stable isotope ratio signatures on the bulk silicate Earth due to partitioning between the metallic core and silicate [1]. Enstatite chondrites (E-chondrites) are the only primitive meteorite group with stable oxygen isotope compositions similar to Earth [2]. The Echondrites also possess a metal phase with substantial amounts of Si. W...
متن کاملCoordinated Stem and Nanosims Analysis of Enstatite Whiskers in Interplanetary Dust
Introduction: Enstatite whiskers (<10 µm length, <200 nm width) occur in chondritic-porous interplanetary dust particles (CP IDPs) [1], an Antarctic micrometeorite [2] and a comet 81P/Wild-2 sample [3]. The whiskers are typically elongated along the [100] axis and contain axial screw dislocations, while those in terrestrial rocks and meteorites are elongated along [001]. The unique crystal morp...
متن کاملHf-W Chronometry for an Early Differentiation in the Parent Body of Ureilites
Ureilites are primitive achondrites that are composed mainly of olivine and pyroxenes with abundant interstitial and crosscutting carbon polymorphs, Fe-Ni metal, sulfides, and silicates. Studies of ureilites indicate that the parent body went through a series of igneous processes, while, at the same time, ureilites contain features that can only be explained by mixing of primitive nebular mater...
