Unique evidence of fluid alteration in the Kakowa (L6) ordinary chondrite
Meteorites preserve evidence of processes on their parent bodies, including alteration, metamorphism, and shock events. Here we show that the Kakowa (L6) ordinary chondrite (OC) preserves both shock-melt veins and pockets of detrital grains from a ...

Early evolution of Solar System small bodies proceeded through interactions of mineral and water. Melting of water ice accreted with mineral particles to the parent body results in the formation of secondary minerals, the so-called aqueous alteration ...

Magnetic classification of stony meteorites: 2. Non-ordinary chondrites [PDF]
A database of magnetic susceptibility (χ) measurements on different non-ordinary chondrites (C, E, R, and ungrouped) populations is presented and compared to our previous similar work on ordinary chondrites. It provides an exhaustive study of the amount

Metamorphism of CO and CO-like chondrites and comparisons with type 3 ordinary chondrites [PDF]
P(論文)In order to explore their metamorphic history, thermoluminescence data have been obtained for 10 CO or CO-related chondrites from the Antarctic. Six have TL properties indicating low to intermediate levels of metamorphism, while Lewis Cliff 85332 ...

Extended chronologies of aqueous alteration in the CM2 carbonaceous chondrites: evidence from carbonates in Queen Alexandra Range 93005 [PDF]
The Antarctic CM2 carbonaceous chondrite QUE 93005 contains four compositionally distinct carbonates, namely breunnerite, calcite, dolomite and a Ca-poor dolomite. These carbonates can form monomineralic grains, or may be intergrown as bimineralic grains

THE EXISTENCE OF GROUPS OF METEORITE-PRODUCING FIRE-BALLS AND METEORITES IN COMET-LIKE ORBITS
This paper discusses the existence of groups of meteorite-producing fireballs and ordinary chondrites in the Earth-crossing Jupiter-family comet-like (JFC) orbits.

Native Platinum in the Ordinary Chondrite
The article presents the first results of the study of native platinum extracted from chondrite. The native platinum forms microinclusions in carbonaceous matter andchromites, which are found in ordinary chondrite. Native platinum forms micrograins and aggregates of cubic microcrystals, most of which are free from impurities.

The dynamic strength of an ordinary chondrite [PDF]
Abstract– Dynamic and quasistatic unconfined compression experiments were performed on samples of the L5 ordinary chondrite MacAlpine Hills (MAC) 88118. The dynamic compressive strength measurements are the first of its kind for a stony meteorite, and indicate that the material tested here exhibits significant increase in compressive strength with ...
