What Martian meteorites reveal about the interior and surface of Mars
Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total
of 262 individual samples originating from at least 11 ejection events. Geochemical …

[HTML][HTML] In-situ phosphate U-Pb ages of the L chondrites
The thermal history of asteroids is recorded by the radioisotopic ages of meteorites that
derive from them. Radioisotopic ages may date a number of events, such as the cooling of a …

Natural Fe-bearing aluminous bridgmanite in the Katol L6 chondrite
Bridgmanite, the most abundant mineral of the Earth's lower mantle, has been reported in
only a few shocked chondritic meteorites; however, the compositions of these instances …

Investigation of the shocked Viñales ordinary chondrite (L6) meteorite fall–implications for shock classification, fragmentation, and collision dynamics
The effects of collisions on the evolution of asteroids, ranging from local fracturing to
brecciation or even to catastrophic disruption, depend primarily on the encounter velocities …

Discovery of nanophase iron particles and high pressure clinoenstatite in a heavily shocked ordinary chondrite: Implications for the decomposition of pyroxene
Although pure metallic iron (ie that with an Fe content of greater than 99%) commonly occurs
in achondrites, and within the returned soil from asteroids or the Lunar surface, it is rarely …

Complicated pressure–temperature path recorded in the eucrite Padvarninkai
High‐pressure minerals in the eucrite Padvarninkai were investigated. Parts of anorthitic
plagioclase and tridymite in the host rock of Padvarninkai vitrified, indicating that the shock …

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 …
