| description | Litho-mineralogical and structural-formation generation features of Upper Devonian-Carboniferous crusts of weathering on terrigenous-carbonate rocks, kimberlites and deposits enriched by products of their redeposition, have been studied, that allowed restoring of the specific features of upper Paleozoic productive horizons generation of the main diamondiferous regions of the Siberian platform, and then, the areas, favorable for generation and preservation of kimberlite (including diamondiferous) material dispersion haloes, have been distinguished within them. Analysis of Upper Paleozoic deposits facies, as well as specific features of their location, has allowed to establish that denudation of the rocks of the region was insignificant since the moment of their crust formation and up to completion of upper Paleozoic sedimentation, and occurred only along the stream flows. The omnipresent availability of crusts of weathering on terrigenous-carbonate rocks of lower Paleozoic, preserved from washout by upper Paleozoic deposits, points on it. These formations are usually elongated in the form of narrow streams and represent fragments of most initial erosion of the crusts of weathering in post-Carboniferous time. That is why, at such minimal shear, practically all kimberlite minerals, occurring in Upper Paleozoic deposits, are redeposited from more ancient pre-Lapchanian formations. The necessity of differentiated approach to studying formation conditions of various facies of diamondiferous upper Paleozoic deposits of continental and coastal genesis has been substantiated, and firstly — studying of their specific features. The complex research is required, with application of structural-tectonic, lithological-facial and formation-cyclic analyses, which would allow allocating specific areas favorable for generation of ancient placers of diamonds or discovering kimberlite pipes. |
