geological history on earth: at some time in the past

Scientists first suspected that the black diamond is not produced in the earth due to the distribution characteristics of the mineral unusual. Although many places all around the world output of diamond, but at present only in Brazil and in non in both countries found black diamond. But the two are not natural geological conditions of any other typical diamond producing areas have -- which means that the diamond formation geological effects may not be normal, but there are other different causes. There are two things that prompted the researchers will they find black diamond eyes space: nitrogen and hydrogen. The researchers used infrared spectrometer on the two kinds of elements in the minerals were observed. They will observe the spectrum of ore heating and its produce. The research results show that the existence of single atom distribution of nitrogen element in the form of a black diamond, not and other conventional diamond in that combining state. The study also found that there are a lot of hydrogen atom in the mineral layer on overlay. To sum up: that is to say, spectral analysis results obtained are much like a produce spectral emission from supernova explosions after the meteorite should have and absorption characteristics. This finding reveals surprising glimpse of geological history on earth: at some time in the past, our earth once and some produced in the supernova 20~30 million years ago the debris came into contact. To survive in this dramatic universe outbreak in debris falling in the tiny earth. Perhaps the debris at the time and has a diameter of 1 miles wide, but when it entered the earth's atmosphere breaks into a lot of debris fell on today's African and South American continents. Clastic body these chastened fall corner of a small universe on the planet after years of erosion have been depleted, they are now found in humans, a special Diamond Black porous.
