Abstract
Diamondites are fragments of polycrystalline diamond and intergrowths of silicates (mostly garnet┬▒cpx; however they do not contain olivine). Open cavities lined with euhedral diamonds imply the presence of fluids during crystallisation. It can be demonstrated that silicates and diamonds very likely grew synchronously from the same fluid (1, 2). It has been suggested that these" polycrystalline diamonds" should be regarded as rocks, termed diamondites (1, 2); this nomenclature has been followed herein.Organic-like'carbon and ...
