A study of secondary alterations of felsic effusives with reservoir properties from the top of the West Siberian pre-Jurassic complex (Tomsk Region) was performed. The lithological, petrographic, and mineralogical features of these rocks indicate their alterations by low-temperature hydrothermal solutions, while the weathering products that are widespread at the top of the basement have not been clearly identified. The reservoir properties of the studied rocks are probably due to fracturing and leaching.
