Typomorphism of diamonds from the Snegurochka pipe, Arkhangelsk Region, based on IR spectroscopy
Otecestvennaa GeologiaDistribution of the structural impurities and defects in diamonds from the Snegurochka pipe located in the Zolotitskoye field was studied using IR spectroscopy. The diamonds are dominated by crystals with an elevated degree of nitrogen aggregation, which is not typical for diamond pipes at the M. V. Lomonosov deposit in the Arkhangelsk Region. Compared

Structural impurities and defects in diamonds from placer deposits of the Near-Sayany Region were first investigated using the IR-Fourier spectroscopy technique. The diamonds are dominated by individuals (the main population) with relatively low both the total nitrogen contents and the degree of its aggregation in the crystals. For the most part, these

The results of mantle nodule investigations in kimberlite diatremes of the main Siberian Platform diamondiferous regions were analyzed. Morphology and chemistry of garnets, chrome-diopsides, clinopyroxenes, olivines, picro-ilmenites, chromites, chrome-spinellids and diamonds were investigated in detail.

New data of typomorphic features of diamonds from placers in North Timan
Moscow University Geology Bulletin, 2009The morphological and spectral-optical properties of diamond crystals from placers in North Timan rivers have been studied with IR-spectroscopy and cathode luminescence methods. As a result, correlation between external characteristics of diamonds (size and degree of mechanical damage) and number of optically active centers has been revealed. The habit

Typomorphic characteristics of the Ural diamonds (from FTIR spectroscopy data)
Russian Geology and Geophysics, 2013Abstract Natural diamonds from the Ural alluvial deposits have been studied by FTIR spectroscopy. It is shown that these diamonds are similar in some typomorphic features, such as nitrogen content and aggregation state, to the diamonds of the Coromandel (Brazil) and Verkhnee Molodo (Lena region, Yakutia) placers and to the diamonds from ...

A new method of combinatorial symmetric analysis of the real shape of diamond crystals has been improved and tested. Diamond crystals have been studied from significant samples of octahedral and dodecahedral crystals from large kimberlite and placer deposits in the Yakut diamond-bearing province, including the Malo-Botuobinskoye, Daldynskoye, Alakit ...
