Abaut lithologic and stratigrafi features of ancient diamondiferous thicknesses

Over the past 60 years, in connection with the discovery of primary diamond deposits on the Siberian platform (JV), the diamond mining industry has been created and is successfully developing. The explored and approved reserves of primary and alluvial deposits make it possible to mine diamonds in ever-increasing volumes. To replenish diminishing reserves of diamonds, it is necessary both to discover new diamondiferous kimberlite diatremes and to involve placers in the development. Since the fund of easily discovered and emerging indigenous diamond deposits on the territory of the Yakut diamond-bearing province (YAP) is practically exhausted, their searches have moved to closed areas, where there is a wide development of various facies continental and coastalmarine terrigenous deposits of the Upper Paleozoic and Mesozoic of signifi cant thickness, overlying kimberlite diatremes. Complex research of ancient crusts of weathering on terrigenous-carbonate rocks, dolerites, tufogene formations and kimberlites, as well as products of their rewashing in Mesozoic sedimentary thick layers of main diamondiferous regions of the Siberian platform allowed restoring specifi c features of their structural-formation generation. It is noted that specifi c features of rewashing and redeposition of various crusts of weathering products are typical of Mesozoic time in whole, conditioned by the development of various structural-formation zones in diamondiferous regions. Thus, generation of products formation of weathering crusts rewashing in Malo-Botuobinsky region was determined by the development of two structural-formation zones. Conditions for accumulation of weathering products existed in one of these zones (south-eastern) at Irelyakh time only on slopes of the central part of Angara-Vilyuy superposed sagging. In the second structural-formation zone (northwestern), occupying trappean plateau, crust formation with simultaneous washout and redeposition of products of weathering into occurring nearby local depressions and their partial carry-over beyond the said zone took place practically in the course of all Mesozoic time on elevated plateau-like uplifts. Complex research of ancient crusts of weathering on terrigenous-carbonate rocks, dolerites, tufogene formations and kimberlites, as well as products of their rewashing in Mesozoic sedimentary thick layers of main diamondiferous regions of the Siberian platform allowed restoring specifi c features of their structural-formation generation. It is noted that specifi c features of rewashing and redeposition of various crusts of weathering products are typical of Mesozoic time in whole, conditioned by the development of various structural-formation zones in diamondiferous regions. At MaloBotuobinsky region, the formation of weathering crust rewashing products was determined by two developing structural-formation zones. The studies carried out emphasize the importance of stratigraphic studies at all stages of geological prospecting for diamonds. It is very important to distinguish in the sections of sedimentary strata the horizons enriched with material from local run-off s, with dominant crusts of weathering of various rocks, including kimberlites.
