Манькова Т.В., Суслов С.Б., Исаева Г.А., Казымов К.П.
The petrographic and petrochemical investigations of the Usvinsky formation gabbrodolerites from dikes located in Gornozavodsky district in Perm region were held as the part of a international research scientists group project «Evaluation of mineral base of Perm region for the provision of high quality basalt fiber production «. It is established that the rocks have a homogeneous structure, constant mineral composition and the same character of secondary changes . Gabbrodolerites have little variations in the chemical composition; the acidity module is in average 3.44 . These characteristics corresponds with the main requirements for the rocks for the basalt fiber production. Also, the positive aspects are abundance, dikes exposure, the presence of roads and entrances to them. Negative factor is the presence of quartz in most samples (1-10 %) as a mineral with a high melting temperature. Further works to basalt fiber obtaining from melting furnace will more accurately assess the suitability of rocks the Usvinsky formation for the basalt fiber production.
