Olivin Biography

For success ... [3] - Alexei Tolstoy, “Hyperboloid engineer Garin”, Olivin belt - nothing but metals in liquid state: olivin, mercury and gold. You can break through the mine in the center of Berlin, and the molten gold itself flows like oil, from the depths of the Olivin Belting ... [3] - Alexei Tolstoy, “Hyperboloid engineer Garin”, in the melted Olivin belt, three layers need to be distinguished: the closest to the earth's crust is slags, lava thrown out by volcanoes; The middle layer is olivin, iron, nickel, that is, what meteorites consist of, falling in the form of stars to the ground in autumn nights, and, finally, the third is the lower layer - gold, platinum, zirconium, lead, mercury.

The next shell consists of biotite, sometimes it is likely to join this hybrid mineral - a grenade - and amphibol: IBID. This stone has two more names: Olivin and chrysolite. The guide for gems, during the time of Queen Victoria Chrysoberill, was often mistakenly called Olivin or Chrysolite. But Chrisolit Jewelers belongs to the apatite. Peridote, together with Pyroxen, is found in various rocks of the granite structure that do not contain white elements, and in the same breeds, chrome and nickel are mainly found.

On the other hand, the only earthly breeds containing native iron are peridodite rocks. Large inclusions of this metal were found in the peridotite basalts of the OVIFAC in Greenland; The diamond -bearing iron of the canyon Diablo in Arizona, whose blocks are scattered around the crater, also have volcanic origin. The amazing similarity between meteorites and earthly elements of deep origin led to good to the conclusion about the unity of the composition of the solar system.

From this point of view, meteorites are fragments of a scattered celestial body that accidentally fell on our planet, and the bowels of the Earth should have the same composition with meteorites. Under the zone of rich peridota lies such a zone where the iron and metals close to it are unawsted. Peridot thus is not only the slag of the metal nucleus of the Earth, but also the global slag.

Geological phenomena "volume 1, here it must be said that some minerals in well -known conditions may not show adhesiveness at all. This includes Austitis in effusion rocks. At the same time, other minerals, for which adhesion is not characteristic, sometimes show excellent adhesion precisely in epo -faced rocks. I have already mentioned this in the Crystalloptics Code regarding Olivin.

This is a very important circumstance in the regard that sometimes, seeing the adhesion of Olivin, you can take it for Pyroxen and, without checking it in a very simple way, make a gross mistake means your mineral does not pyroxen and not an andalusit, but maybe olivin; This mineral is rhombic, and it can be seen from the signs that normal cracks only with the pinacoid dilia of the rhombic mineral always give direct fading these posterior biotid -shaped substitution products of Olivin and the composition and optical properties.

For the most part, their color is biotite, it means brown, red -brown, orange -bruise, sometimes red. They behave in exactly the same way as biotite, and differ from the latter, sometimes only by refraction and duality. Occasionally, these shells continue further. The next shell consists of biotite, sometimes it is likely to join this hybrid mineral - grenade - and amphibol.

It turns out a group of squads or squads, where one mineral generation, represented by one species, is bordered, as a shell, by another mineral generation, another mineral species. If you notice or accustomed yourself to observe the interference coloring, then you never mix the epidote with a very similar Olivine or monoclinic pyroxen in grinds, and I advise you to turn to such a way of distinguishing coloring when you have been convinced that the epidote mineral we are studying.

With a painted epidote, having a pistachio -green coloring in slices, olivin cannot be mixed because olivin is a colorless mineral in the grinder. Then Olivin can be distinguished from the epidote in presence in the last dod. If in those breeds where you can wait for Olivin, you saw adhesion, then it, being developed on the Pinacoid plane, should behave differently in the rhombic olivine than the adhesion of the software or the monoclinic epidote.

The structure of chrysoberill is very reminiscent of the structure of Olivin; Like Olivin, Chrysoberill crystallizes in rhombic Singonia, forming dull prismatic crystals. Hyperten is black-green, in the form of grains from 1 to 4 lines with a length. White grains are leaflet, mostly pearly shine and shine through in the edges. Inflasticity is not often, but all the same it is noticed, so these grains are likely label.

In addition, brown -out -of -the -rod grains of Olivin are also visible. The breed contains so many magnetic iron yields that our compasses were completely in a disorder; Some of the beaten pieces were polar magnetic.The study of the Pallasites leads to the same conclusion - rounded, consisting mainly of Olivin, nest -shaped comments. According to Goldschmidt, they formed as follows: liquid silicate drops, being in a stream of molten metal, froze in it.

In a strong field of gravity, they could not hold on for a long time: soon both minerals would be divided, and only a very quick hardening could prevent this separation. All these considerations speak against the hypothesis that meteorites are debris. Pieces of green Olivin remember the Olivin Belt of engineer Garin? In particular, the subject of a lively discussion is the assumption that diamonds were formed in the process of forming kimberlite tubes as a result of the chemical reactions of Olivin and Ilmenite with limestones ...

[15] - Boris Gorszev, “diamond”, the lunar soil contains a lot of minerals like earthly pyroxsen, oliggois, olivin, ilmenite. According to historical geology, the platforms for a long time 1, billion. This rise is easiest to explain by the fact that the water, which is constantly released from the bowels of the Earth, reacted with Olivin, and a layer of flooded certified rocks was gradually formed in the bottom of the earth's crust - the basalt layer.

In our opinion, under the platforms, the basalt layer of the earth's crust is composed of slightly serpentinized mantle rocks. Total in - gg. Thus, in the jewelry qualities of the gem, the Ural men were not mistaken. But they called him incorrectly - chrysolite, which translates from Greek as a gold. Mineralists, by chrysolite, mean the yellowish-green transparent variety of Olivin.

Compared to demantoid, chrysolite is just a little cub in a pebble. The light areas of the "continents" mainly consist of breeds that are very similar to earthly anrtositos of gray stones with a high aluminum content. Geologists often find them in the faults of the earth's crust. They are familiar to us, because they are kept in almost any river sand. What does the word “peridot” mean is not known for certain.

There is a version that it has Arab roots and, possibly, came from the word “Faridate”, which means “gem” in translation. As it turned out later, neither olivin nor chrysolite have nothing to do with Chrysoberil at all, these are completely different minerals. If this definition of the system is confirmed, then this will be proof of dimorphism of the entire group of Olivin, Comrade Dokuchaev, I have already made several drugs of Labrador, Olivina, etc.

Dokuchaev, and the sparkles sunk into my soul. I knew that the dark breeds rich in Olivin and Pyroxen are often carried with them, especially in Norway and Canada, the brilliant ores of copper and nickel, and the decision to go to Montchu quickly ripened next year at all costs. He was apparently known to the Greco-Roman world. Later, the crusaders brought him to Europe from their campaigns.

He is quite famous, but, to tell in truth, does not differ in particular beauty; It is little transparent and painted in an ugly dirty color. No wonder there is an old French proverb on his account, saying that if you have two Olivins, then one of them is superfluous. This cannot be said about our Ural chrysolithic, since there are stones of rare beauty that can withstand comparison with the best of the best gems.

And if the name “chrysolite” is given to him, from a formal point of view, and incorrectly, then it approaches him not only no less, but much more than to the genuine chrysolite-olivine. According to its golden brilliance, our stone is a more “real” chrysolite - goldmaker. Then a shakel grew out of chrysoprazov, a muskat from Olivin and quartz, radiating fabulous sheaves of sparks - red, purple, yellow.

The Olivin belt, according to scientists, lies at a significant depth under the thickness of the lighter breeds of the earth's crust; он состоит из более тяжелых минералов в том числе — и в большом количестве — минерала оливина и отделяет легкие поверхностные слои от металлического ядра Земли. It is believed that iron meteorites, which consist mainly of nickel iron, represent the fragments of planetary nuclei, and stone meteorites, consisting of olivin and other iron -rich minerals with interspersed of nickel iron, give us the concept of the composition of the substance of the olivine belt.
