In a meteorite discovered unknown mineral

In ancient meteorite found unknown mineral

American geologists at the California Institute of Technology have found in the Allende meteorite new mineral, called "Pang". Article describing pangita published in the journal American Mineralogist, and its summary can be read at Wired Science.

Scientists have studied the meteorite using scanning electron microscopy, thus inside the celestial body failed to detect microscopic inclusions of an unknown mineral. Chemical analysis showed that it has the formula (Ti 4 +, Sc, Al, Mg, Zr, Ca) 1.8 O 3. Therefore, it contains as common in the earth's crust elements and zirconium and quite rare scandium.

According to geologists, Pang in a meteorite formed a very long time — about 4.5 billion years ago. Thus, the mineral is present in the protoplanetary disk around the Sun before the formation of the Earth and other planets.

Antiquity pangita explains the choice of the name that was given mineral geologists. It comes from the name of a mythical Chinese giant Pan Gu, who sweep the huge ax separated from the Yin and Yang did so Heaven and Earth. The Commission on New Minerals, NOMENCLATURE and classification of the International Mineralogical Association approved this name.

Allende meteorite fell to Earth in 1969, in the fall he broke into many small pieces. The total mass of the meteorite was about five tons, of which three are gathered scholars. Now part of a meteorite found in various academic institutions around the world.

Recently, scientists have published an analysis of Martian meteorite ALH84001 and found that those organic substances which it contains are of volcanic origin. Therefore, they can not be a product of life possible Martian life.
