Mezosiderity

Among the latter are the most common type of chondrites, are composed of fine-grained gray or black mass, resembling volcanic tuff, in her apparent peculiar beads and grains of olivine, bronzite, nickel iron, etc., the origin of these grains has not been elucidated. In terrestrial rocks chondrites are of no close resemblance, on the contrary, some other meteorites, especially the so-called Eucrite consisting of anorthite (lime feldspar) and augite, are many similarities with rocks of the Earth (for example, with some lavas of Iceland). The following is called a meteorite Chassignite consisting of olivine with the included chromium Zheleznyak, it is no different from almost anything quite common in the land of olivine rocks. We've gone too far, if seniority list all the less important modifications of meteorites, we give is only one kind of them, drastically different from the others, and especially interesting by its composition, the so-called carbonaceous meteorites, their example may serve as meteorites STE France (1806), Kolda, Bokkefelda (Cold Bokkefelda) in the Cape Land (1838), Kaba near Dobretsina in Hungary (1857) and Orgeylya in France (1864). They represent the earthy crumbly mass and contain compounds of carbon with hydrogen and oxygen, the nature of these compounds were not determined. Of particular interest are meteorites because of their similarity to the formations, found in the earth by comparison we can make a lot of important conclusions about the properties of our planet, are not subject to direct observation.
