California: An interesting piece of news has come from the world of science that a mineral was predicted decades ago which has now been discovered at a depth of 660 km.
Inside a diamond are found traces of a mineral that has never been seen before. The mine has been dubbed ‘Dumoite’. Although a similar type is found in the world, Dumoite is formed deep in the earth under high temperatures and pressures.
Inside the diamond, found in the African country of Botswana, are trapped small pieces of black mineral and have been searched for a long time. Oliver Schoner, head of the research team and head of geological chemistry at the University of Nevada, called it Dumoite. It contains calcium silicate CaSiO3 but may contain radioactive isotopes of uranium, thorium and potassium.
The mineral was theoretically predicted in 1967. Experts have identified its location as the mantle where the temperature is high and the pressure is abnormal. The mantle is found between the crust and the core. By understanding Dumoite in this way, we ourselves can know the terrestrial structure, plate tectonics and geology.
Experts believe that the mine is formed under special conditions at a depth of 660 to 2700 km where heat and pressure prevail. That is why it is seen inside a diamond that survives at high temperatures.
Although calcium silicate pyruvate is made in the laboratory, it is naturally seen for the first time.
It should be noted that this diamond was recovered from a mine in Botswana in 1987 but it reached the California Institute of Technology through various hands where it was researched for many years and on November 11 it was announced in a research paper. In case done.
When it was first pierced with a laser, traces of calcium were found inside. It turned out that it was calcium silicate and finally it turned out that this crystal is actually calcium silicate pyruvate. About five to seven percent of the ground mantle may contain this mineral.
It should be noted that this discovery was not made at a depth of hundreds of miles but was found in a diamond mine and it is believed that it may have reached the top due to some process.
