Abstract

Using the methods of quantitative infrared spectroscopy and the X-ray phase analysis it is analyzed sedimentary chalk of five different domestic deposits compared to chemically precipitated and import calcite. Presence of calcite, dolomitic, aragonite in their composition is fixed. It is given a quantification of the content (for half-width within the 562-1047 cm-1 for imported calcite, 440-703 cm-1 for the national sedimentary chalk and 530 cm-1 for the chemically-deposited chalk, and the ratio of the intensities of characteristic absorption bands of carbonate anion respectively 10,38-45,33; 26,80-47,33 and 35,15) of the main structure minerals of these kinds of carbonates. It is received the data confirmation of IR spectroscopy by X-ray phase analysis of the main types of natural chalk and it is obtained quantitative structure of main content (calcite, dolomite) and extrinsic (quartz, kaolinite, iron hydroxide) minerals. According to the parameters of characteristic absorption bands in the range of 712-876 and 2512-2522 cm-1 modification of calcium carbonate - calcite – it is conducted differentiation of quantitative indicators, depending on the origin of the material. It is noted greater uniformity of mineralogical composition of import carbonates.

These data allow formulate reasonable frameworks of use of domestic sedimentary chalk and assess its competitiveness compared with chemically-deposited chalk and Turkish calcite.
