Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 … It was the first meteorite reported from Egypt, the first one to suggest signs of aqueous processes on Mars, and the prototype for Nakhlite type of meteorites.

There are also interesting notes about the state of meteorite classification in 1912 – including the deduction that Nakhla represented a new class – and the origin of meteorites. The largest Martian meteorite is Zagami at 18.0 kg (40 lbs), followed by Yamato 000593 and paired stones at 15.0 kg (33 lbs), Tissint at >12 kg (>26 lbs), Sayh al Uhaymir 005 and paired stones at 11.2 kg (25 lbs), Dar al Gani 476 and paired stones at 10.4 kg (23 lbs), and the numerous stones of Nakhla …

Nakhla is one of these extremely rare Martian meteorites. The Nakhla meteorite, one of the SNC group of putative Martian origin, is an igneous rock, a cumulate of augite and olivine, that does not represent a magma composition. Main page of the Antarctic Meteorite Collection at NASA Astromaterials Curation.

The structure and chemical composition … Finally, the spectrum of jadeite looks totally different from Nakhla, and is a very poor match.

2013). Nakhlites are a group of Martian meteorites, named after the first one, Nakhla meteorite. Nakhla is the namesake for the nakhlite meteorite type group, made up of 14 distinct meteorites, and defined by the Meteoritical Society as clinopyroxenites or wehrlites formed as cumulate rocks. SEM image of a chip of the Naklha meteorite, depicting possible biomorph material: the larger, broad knife-like and the small, donut-shaped features. Nakhlites are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago. meteorites originated on Mars comes from the measurement of gases trapped in one meteorite’s interior which matched the data measured by the Viking lander in the Martian atmosphere.5,10–12 The Nakhla meteorite can be described as an olivine-bearing clinopyroxenite consisting mostly of augite with less The isotopic composition of oxygen in the siderite has been determined with the Manchester ISOLAB 54 ion microprobe.

The author reports the elemental and isotopic composition of the noble gases in various fragments of the Shergotty, Nakhla, and Chassigny meteorites. There are 13 known nakhlites, the first of which, the Nakhla meteorite, fell in El-Nakhla, Alexandria, Egypt in 1911 and had an estimated weight of 10 kg. Nakhlites.

Conclusions presented earlier which were based on results for trapped Ar, Kr and Xe only, are reaffirmed by the complete set of data. 1911. igneous meteorites, and its chemical composition implies formation near the quartz-fayalite-magnetite (QFM) buffer (e.g., Reid and Bunch, 1975).
