Mineralogical Search Signs for Assessment of Prospects of Diamond Capacity of Ukraine (by Physiographical and Photoluminescent Data)

Some important questions concerning the application of methods searches diamond deposits on direct search signs - finds diamonds are considered and indicator minerals kimberlites (IMK). The probable reasons for low efficiency dressing-mineralogical method in Ukraine named. article is based materials research found different age placers (~1300 crystals); from Arkhangelsk province (~6000 metamorphic rocks Kazakhstan deposit Kumdy-Kol (~200 Yakut (~600 crystals root springs ~700 placers). A physiographic description was made all these intensity color photoluminescence (PhL) were recorded. For some crystals, about 600 spectra taken at a temperature 77 K. "Dniester" type highly defective Ukrainian placers, data Raman spectroscopy given. material partly result our research, attracted literature sources. Finds terrigenous Ukraine, their territorial age, possible sources income analyzed. comparison with indigenous genetic performed. comparison, we studied that obtained (with complete removal gross technological samples) kimberlite pipes province. We performed established particle size distribution morphological pipes. Based studies, convincing conclusions drawn industrial diamond-bearing capacity bodies this study large number extracted Neogene other allowed usto perform comparative not only morphology but also frequency centers (spectra 77K). These compared provinces. It which physical properties close to how they differ, contrasting features sets types determined. has been Bilokorovichi world have kimberlite, nature surfaces, set PhL centers, indicates long stay sedimentary reservoirs ages. IMK, territory Kirovohrad block Shield (USh), revealed known area Gruzka prospects worth further mineral testing. chemical composition IMK Priazovsky USh non-diamond-bearing or non-industrial capacity, confirmed by few (3 crystals) natural diamonds. green microdiamonds turned out be man-made debris. Numerous Poltava-Sarmatian specific properties. source Black Sea coast Azov. analysis, it concluded clear discovery deposits. Taking into account current economic feasibility degree primary diamonds, opinion authors should north-western (Ovruch-Bilokorovytsia) part, as well within Dnieper Kirovograd blocks. In course operations, necessary abandon analysis IMC less than 1 mm pay attention mainly pyropes most informative IMC.A prerequisite exploration work large-scale mineralogical test aimed detecting least 1.0 limiting fractions will allow reduce costs, determine search.Only results works concludethe allocated areas.
