Abstract

Basing on generalization of large actual material on complex investigation of diamond its characteristic in Upper Paleozoic and Mesozoic sedimentary thick layers of the Siberian platform is provided. It allowed receiving new data on composition features and distribution of diamond in recent sediments of main diamondiferous re-gions of Lena-Anabar, Central-Siberian and Tungusskaya sub-provinces. Identified in some diamondiferous regions proximity of typomorphic features of diamonds in sedimentary thick layers of these ages testifies about formation of these collectors due to washout of more ancient productive layers or Middle Paleozoic primary sourc-es. Polygeny of mineralogical associations of diamonds from different in age plac-ers within some diamondiferous regions was noted, which may be successfully used when forecasting and prospecting primary sources of the mineral
