The FeO-rich minerals and abundant late-stage melt pockets and maskelynite all argue that QUE 94201 is the most evolved member of this basaltic shergottite evolutionary trend.
In this paper, we present a mineralogical and petrological study of QUE 94201 and discuss its mineralogical differences and simi- larities to the other basaltic shergottite, EETA79001 (lithology B), as well as to luna...
Approximately 80% of the ~150 martian meteorite specimens recovered by mid-2015 have been classified as shergottites. QUE 94201 is one of 10 meteorites more specifically classified as a 'basaltic shergottite' at NASA'...
79001 (TS 69) and QUE 94201 (TS 6, 37, and 38) were initially examined under a polarizing optical microscope. Backscattered images, elemental maps and quantitative analyses were acquired using the Cameca SX-100 electr...
Basaltic shergottites are commonly described as having crystallized from magmas that contained entrained or cumulus pyroxenes. Complexly zoned clinopyroxenes in QUE94201, a newly recovered Antarctic shergottite, are s...
It is composed of laths or globular grains of transparent or translucent maskelynite plus dull or glassy-black pyroxene. Several mafic-rich areas, as large as 5 x 4 mm, were noted. Oxidation is scattered throughout th...
The Opportunity rover of the Mars Exploration Rover mission encountered an isolated rock fragment with textural, mineralogical, and chemical properties similar to basaltic shergottites. This finding was confirmed by a...
QUE94201 (QUE) and Dhofar 378 (DHO) are basaltic shergottites that are mainly composed of pyroxene and plagioclase glass. These two shergottites suffered severe shock, which generated abundant impact melt and vesicula...
Abstract-Quantitative petrographic analysis, using the crystal size distribution (CSD) method, provides a novel approach for examining the crystallization histories of basaltic shergottites.
Introduction: QUE 94201 (QUE) is a basaltic shergottite containing subequal amounts of pyroxene and plagioclase, the latter having been converted to maskelynite by shock (Fig. 1) [e.g., 1-3].
