Abstract

A small dike of unknown age was found on the territory of the Kanin-Timan region within the Middle Timan along the Lunvozh river. Our studies revealed that the rocks, composing this intrusive body, corresponded to basaltic andesites according to the content of the main rock-forming elements. They were almost completely recrystallized and composed of chlorite (30—40 %), carbonates (25—40 %), albite (10—15 %), quartz (10—15 %), muscovite (5—8 %) and plagioclase (less than 1 %). Accessory minerals were represented by apatite, monazite and rutile. Ore minerals included pyrite, chalcopyrite, and cobaltine. According to the mineral composition and petrochemical characteristics, the rocks composing the dike body along the Lunvozh river, differed from the basites of the Middle Riphean Middle Timan and Devonian Kanin-Timan complexes identified in the Kanin-Timan region.
