.Chunks of stone Strange It Contains 30 Thousand Diamonds

Chunks of stone Strange It Contains 30 Thousand Diamonds - geological researchers discovered a strange boulder filled with tens of thousands of tiny diamonds. Chunks of stone found on the mining Udachnaya Russia is viewed can help researchers unravel the geological history and the origins of the emergence of gemstones on Earth.

Chunks of stone Strange It Contains 30 Thousand Diamonds

Reported by Live Science, Thursday, December 18, 2014, the boulder was found in at least 30 thousand diamonds that light up when exposed to X-ray tomography scanner. Researchers say, the concentration of diamonds in the rock millions of times larger than a typical diamond seed, which is an average of one to six carats per tonne, or roughly one-fifth of a gram.

Interestingly, when exposed to X-rays, each mineral stone that emits color bebeda. For example emit black diamonds.

"Mineral Association will tell us the origin of this stone, which is a strange one," said Larry Taylor, a

geologist at the University of Tennessee, Knoxville, USA.

Researchers are still not able to reveal how the diamonds were formed in the stomach of the Earth. Scientists think the diamond appear deep in the Earth's surface, between the crust and the core of the Earth (mantle).

Well, volcanic eruptions eventually bring the diamond rose to the surface layer of the Earth. Unfortunately, on the way to the surface, some diamonds were destroyed, leaving only the crystals on the surface of the Earth.

From the boulder that, tens of thousands of diamond unite in a tight binding. Meanwhile, the crystal only has a height of 1 mm, was found in the octahedral layers.

Other spots in the slab is garnet red and green olivine and pyroxene. 3D models built from X-rays, revealed when diamonds are formed after mineral garnet, olivine and pyroxene.

Taylor said that overall, the findings suggest that diamonds crystallize from the liquid separated from the subduction of oceanic crust, which kemunginan consisting of solid stone or peridot. These findings still harbored a mystery, including the chemical processes of diamond formation.

"Chemical reactions in the formation of the diamond is still a puzzle," explains Taylor.

Meanwhile, another researcher who was not involved in the study, Sami Mikhail, has other explanations of chemical processes are rare.

"The source of the unusual chemistry that could be really old formation that has gone down in the mantle in a long time," said Carnegie Institution researcher dor Science, Washington DC, USA.

The findings of this rare stone has been presented to the annual meeting of the American Geophysical Union earlier this week. Furthermore, the results of this study will be published in Russian Geology and Geophysics for the January 2015 edition.
