摘要
Collections of Early Triassic rocks sampled from three outcrops on the SW slope of the Pai-Khoi Ridge are studied. The magnetic polarity succession r-n-r is established from the prefolding characteristic component of natural remanence in sedimentary rocks and a basaltic nappe. According to stratigraphic data and isotopic dating of the basaltic nappe, the studied parts of the lower subformation of the Lestanshorskaya Formation correlate with the central part of magnetic zone R1T1 of the European Russia magnetostratigraphic time scale. The angles of rotation in the horizontal plane are estimated for the studied Early Triassic Pai-Khoi structures with respect to the East European platform.
