Abstract
The carbon and oxygen isotope composition of secondary carbonates from acidic effusives in the top of the pre-Jurassic complex of the West Siberian plate (Tomsk Region) was studied. The siderite values of δ13С (VPDB) and δ18О (VSMOW) vary from –6.6 to –2.4‰ and from 7.8 to 12.3‰, while the calcite values vary from –8.9 to –8.4‰ and from 2.5 to 3.7‰, respectively. The light oxygen isotope composition indicates that the carbonates were from medium- and low-temperature hydrothermal solutions.
