Wow even cooler than I was expecting. The pallasite looks incredible. They all do, but that one pops out. I wonder how they know where some meteorites originated if we haven't been to mercury etc. to take samples? Google time....
NWA 2999 Ultra-Rare/Unique Angrite Mercury Meteorite
The Case For Samples From Mercury!
What I have is a
.358 gram part slice of NWA 2999, the most interesting Angrite ever found. NWA 2999 was brought back from a Moroccan expedition in August of 2004. This meteorite was not recognized as being anything exceptional until April of 2005, when Greg Hupé found time to investigate the entire haul from this trip. After examining hundreds of suspected meteorites he found 12 complete stones totaling 392 grams that looked somewhat different from the rest. Nobody would have guessed these stones would turn out to be ultra-rare Angrites, because texturally they look completely different from what most would expect. A sample was liberated from one of the stones and sent to Northern Arizona University and a second sample from a different stone was sent to the University of Washington. Both laboratories found that the mineral compositions matched those of Angrites. A decision was made to sample and test each of the 12 stones because the potential for additional important findings is great.
NWA 2999 is unique in having unusual mineral compositions that mimic terrestrial processes leaving some scientists to believe these types of stones could have only formed on a planet-sized body. Unlike most of the other known Angrites, NWA 2999 was found to be a plutonic rock, meaning that it formed underground and was not extruded in a lava flow. Interestingly enough, this sample lacks vesicles. The magnitude of these findings prompted scientists to send off a specimen to the Carnegie Institution in Washington D.C. for oxygen isotope testing. The results confirmed that NWA 2999 is the 10th member of the unusual and scarce Angrite group.
My NWA 1195 RARE Mars/Martian Shergottite Meteorite is a
224 milligram part slice of Northwest Africa 1195, a Martian Olivine-Orthopyroxene-Phyric Shergottite found near the Safsaf Oasis on the Algerian/Morocco border. This rare Martian meteorite represents the most primitive lava yet discovered from the planet Mars. It was found in two pieces that were located at separate times totaling only 315 grams. Even though the two pieces had weathered apart for thousands of years they fit back together perfectly. It is the 26th Martian meteorite discovered and is considered by the very few collectors who own a specimen to be twice as lucky as the now famous "Lucky 13" Shergottite because it was found in two parts.
And my NWA 5406 Lunar Moon Meteorite is a
.124 gram part slice of NWA 5406, a Lunar Feldspathic Impact Melt Breccia meteorite found near Siksou Mountain in Western Sahara (Morocco) in 2007. It consists of 6 stones paired with the two stones of NWA 4936. This lunar specimen contains an unusually large amount of free iron for a lunar sample and has many small vesicles within the melt veins.
