...Soviets have some convincing evidence for their claim. Using special high-temperature ovens, they incinerated peat collected from the region. In the ashes they found many strange, irregularly shaped and extremely hard black grains, which laboratory examination revealed to be tiny diamonds. Institute Geochemist Emil Sobotovich explained that the little diamonds could only have been created under extraordinarily high pressures. Such conditions deep within the earth produce diamonds, which are brought to the surface in eruptions of molten magma through kimberlite, or volcanic, pipes. But extreme pressures also occur during high-velocity collisions between celestial objects; uralites, a class...
...added evidence that the diamonds arrived in a meteorite, Sobotovich cited their level of carbon 14, a radioactive isotope of carbon found in meteorites that have been subjected to prolonged bombardment by cosmic rays in space. University of Chicago Geochemist Edward Anders cautions that even a trace of unburnt peat could produce a high reading of carbon 14. But, based on these levels, the Soviets calculate that the meteorite must have weighed at least 4,000 tons...
