The legendary Chinguetti meteorite is also supposed to be a mesosiderite. The asteroid 16 Psyche is a candidate for the parent body of the mesosiderites. [5] However, a reliable delivery mechanism lacks for Psyche, and spectral analysis indicates the mesosiderites derive from the Maria Asteroid Family [6]
Pieces of Mars rock can command similar prices, with a 4.25-pound piece selling for $63,000, approximately $15,000 per pound. Meteorites from the Moon are even more valuable. A 406-gram lunar ...

Lonsdaleite was first identified in 1967 from the Canyon Diablo meteorite, where it occurs as microscopic crystals associated with ordinary diamond. [5] [6] It is translucent and brownish-yellow and has an index of refraction of 2.40–2.41 and a specific gravity of 3.2–3.3 .
Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, [3] with the exception of the IIE iron meteorite group. [4]
Meteorites composed of 6 wt% or less nickel are often referred to as hexahedrites due to the crystal structure of kamacite being isometric and causing the meteorite to be cubic. Likewise if the meteorite is dominated by the face centered taenite it is called an octahedrite as kamacite will exsolve from the octahedral crystal boundaries of ...
In 2005, Steve Arnold of Arkansas, USA, and Phil Mani of Texas, USA, unearthed a large mass of 650 kilograms (1,430 lb) and in 2006 several new large masses [12] [13] Don Stimpson and Sheila Knepper have found approximately 8,000 lbs. of the Brenham meteorite on their farm property. [14] Huckitta, Northern Territory, Australia. A mass of 1,400 ...
The Orconuma meteorite is classified as an H3-4 chondrite. This classification indicates that it is a type of stony meteorite that is rich in olivine and pyroxene, and it originated from the asteroid belt. The H3-4 classification also suggests that it underwent minimal thermal metamorphism on its parent body. [6]
