TEKTIT
Characteristics of the mineral.
Tectites are molten and frozen vitreous formations that have arisen as a result of the impact of meteorites on the hard surface of our planet. Sometimes they are wrongly called meteorites, but this is not entirely correct. Most often tektites are not fragments of meteorites themselves, but pieces of rocks of earth origin, melted as a result of meteorite impact on the earth. Tectites consist mainly of silicon dioxide (68-82%), their average size rarely exceeds 5 cm. In appearance and properties, they slightly resemble obsidian, but differ from it in chemical composition. The possible presence of tektites is indicated by young craters caused by the fall of meteorites. The name, derived from the Greek word tektos (molten), hints at the role of meteorites in the origin of tektit.
The most famous tektites from Australia, Thailand, Vietnam and the Philippines. There are tektites in the US (Texas). World famous are the Moldavites - tektites (often green) found in the territory of modern Moldova. Find tektites near the places where meteorites fall. The price for tektites in the domestic and world markets is certainly lower than the price of meteorites, but tektit can be sold freely and legally, demand for them exists and is stable for many years. The photo shows on the right and below typical samples of tektites that can be freely sold and bought.
Tectites can be very similar to porous black stones of volcanic origin, but unlike them have a higher density and are significantly heavier than lightweight porous volcanic rocks. Tectites are more expensive.
Magic properties of stones.
Tektites are given special value by their supposedly extraterrestrial origin. The unusual genesis of tektites was already suspected by Australian aborigines, who called these stones heavenly talismans. It is believed that tektites help to establish a connection with the past, useful for mental journeys in time and access to the astral. They contribute to the accumulation and preservation of knowledge. Tectites can protect a person from errors in the mental and emotional spheres, they help to overcome karmic problems. In Thailand, tektites are often used by local healers.
In the photo - kimberlite tektites (melted rocks of quarry ores - tubular, similar to death, tornadoes and "thrombuses") geological bodies in the earth's crust. Beige modifier of pegmatite, demantoid green and grayish agate melted kimberlite tektite from quarrying (result of impact and screwing into the ground of a red-hot rotating bolide meteorite with rotation of surrounding rocks - fused rocks of kimberlite).
The vitrified stones from kimberlite quarries (the rotation of the stone "mixer" in the earth arises under the action of a breakdown of the meteorite of the earth's crust through and through, often the breakdown of a meteoritic bolide goes to the burning magma and below and is accompanied by the rotation of the meteorite of the rocks in the surrounding channel). There are craters, the emergence of which, as a result of meteorite impact, does not cause doubts, although fragments of a meteorite substance are not found in their surroundings - they can be searched inside the earth (kimberlites).
These melted and vitrified (quartz) metamorphosed as a result of the impact and passage of a red-hot meteorite bolt through the earth's crust the stones (have quartz constituents) is a sign of maximum closeness to them of the kimberlite vent - the hole of the kimberlite pipe in the earth's crust, through which, like a tornado, A burning burning meteorite (car), involves the surrounding rocks into rotation and locally melt them with a high temperature (kimberlite carbide metamorphite - metamorphic rocks of the earth's crust of the contact aureole of a kimberlite bolide meteorite). The third type of tektites and metamorphic rocks.
The names of tektites are given by their deposit: Moldavite - along the river. Vltava, Moldavia, in Czechoslovakia, australite - from Australia: georgiaite - from the state of Georgia, USA. These near-meteorite kimberlite colored tektites (modified pegmatite - written granite, green demantoid, golden-green chrysolite with pegmatite, refractory black morion tektite, almost unmelted, and agate-grained gray form) were picked up in Kharkov (Ukraine) - Kharkovites (Kharkov stones) .
Poisonous and radioactive dangerous stones and minerals
** - poisonous stones and minerals (mandatory check in the chemical laboratory + explicit indication of toxicity).
** - radioactive stones and minerals (mandatory check on the standard dosimeter + ban on open sales in the case of radioactivity over 24 milli / g / h + additional measures of population protection).
All rare stones are subject to mandatory inspection at the standard dosimeter for the permissible level of radiation and in the chemical laboratory for the absence of poisonous and evaporating components that are dangerous to humans and the environment.
