New results of paleomagnetic studies of red-colored rocks of the Late Silurian of southwestern Ukraine (Podolian area, the Dniester river basin)
have been presented. Sedimentary unit of red-colored deposits as a part of upperconovsk subsuite of Malinovets series are represented by dolomites
comparable with Ludford stage of the International geological scale, and was studied in two sections. The distinguished medium-temperature component
of magnetization (Ô=53,4ºS, =5,9ºE) corresponds to the direction of the Permian
poles TCMP for the Baltic area that indicates magnetization
reversal of rocks. High temperature (characteristic) component of magnetization distinguished on lots of samples of the Konovsk suite corresponds
to the Silurian fragment of TCMP for the Baltic and is determined by the presence of terrigenous hematite (ti- tanomagnetite) grains
and is, according
to our interpretation, the primary magnetization. Its corresponding paleomagnetic pole
(Ô=19,9ºS, =339,8ºE) is in good agreement with the
Silurian fragment of TCMP. The results are in good accordance with the previous measurements for grey-colored sedimentary rocks of the
Silurian from Podolia.
