摘要
Diamonds commonly occur in kimberlites, lamproites and relative alluvial sediments. Some examples of diamonds discovered in ultramafics have heen reported. Sobolev and Shatsky reported diamonds from high-pressure metamorphic rock from northern Kazakhstan and considered it to be the source of the alluvial diamonds in Pridneprovie region of western U. S. S. R. Diamonds reported here show some similarity to those in northern Kazakhstan, and are the second occurrence in the world, but the first one in China.
