Abstract
The study of the chemical and phase compositions of tripoli from Krasnoslobodskoye deposit in the Tambov region was carried out using modern equipment. Using the X-ray fluorescence analysis, the main elemental composition of the rock under study was established, determined mainly by the compounds of Si, Al, Fe, K, Mg, Ca, Ti, P, S, Na. It is shown that the proportion of silicon dioxide in the sample under study exceeds its content in tripoli from many Russian deposits and neighboring countries. The X-ray phase analysis with subsequent interpretation of the diffraction pattern showed that tripoli contains minerals of amorphous opal, microcrystalline - and -cristobalites as structural forms of silica, as well as small amounts of quartz, illite and montmorillonite impurities.
