In the materials of lava thrown out during the eruption of Plosky Tolbachik volcano in Kamchatka, researchers revealed an original diamonds new type.
Precious stones do not have any in igneous melt, and in volcanic gases under the action of electric discharge, consider professional.
Worldwide precious stones there was a historic event - creating a new kind of diamonds, which they decided to name the location tolbachinski. The stones were identified in the samples of solidified volcanic lava, raised out during the eruption of Plosky Tolbachik volcano.
With all this lava, been recovered several hundred precious stones. "The number of diamonds can be compared only with abnormally high enrichment diamonds lava rocks on the field Dacin in India (77 diamonds in one kg. of the sample) and unusual igneous rocks in Canada (1.5 thousand diamonds in 28-pound test)" - quoted by Regnum news of the Ministry of education and science of the Russian Federation.
In this case, even when viewed with the introduction of specialized hardware Tolbachik diamonds were synthetic, artificially bred. "But it was real diamonds, which, however, differed from all previously-known varieties of valuable stone in most mineral-geochemical data from the combustion temperature to the composition of trace contaminants," said researchers.
Geologists believe that the unusual is not only the final characteristie stones, but also the process of their origin. However all the diamonds formed from a magmatic melt, Tolbachik stones arose from volcanic carbon gas emissions stimulated by the shock of crystallization. As shock experts believe, acted thunderstorm electrical discharges.
Therefore, tabachinsky diamond appeared literally out of thin air - saturated volcanic gas - when lightning strikes. In all of this eruption, when the lava was thrown out, in type fissure eruption in addition is not considered to be frequent.
Only history was recorded on 6 major cases, when lava poured not from the crater of the volcano, and from systems of parallel and intersecting cracks on its slopes - two times in Iceland in the X and XVIII centuries, twice in Mexico in the XVIII and XX centuries, in the Canary Islands in the eighteenth century and in the Tolbachik in 1975-76. New fissure eruption was 7 in a row in the world and second in Kamchatka.
It started in early November 2012 and ended on 9 October 2013 and even got its own name - Fractured tolbachinskoe eruption behalf of the 50th anniversary of the Institute of Volcanology and seismology or TTI-50. The slope of the volcano, the lava was coming down in 2 directions - in the direction of the village Kozyrevsk she traveled 20 km away and to the side of the river Tolud is 10 km away. With all this in the course of its own movement of magma managed to destroy 2 of the scientific base, the building of the natural Park "Volcanoes of Kamchatka" and the surrounding forest.
