In order to prove the synchronicity of magnetization to the Formation of rocks of the Neoproterozoic Katav Formation (Southern Urals), a paleomagnetic conglomerate test was performed. Samples of breccias from two sections of the carbonate Katav formation located in the vicinity of Tolparovo and Katav-Ivanovsk were studied. Petrographic and electron microscopic studies of thin sections and polished sections have been carried out, confirming the similarity of the mineral composition in the fragments and matrix. The qualitative assessment of the chaotic directions of magnetization of the fragments according to Graham was verified by more stringent Rayleigh and Hodges-Ajne criteria. The results allow us to state that the conglomerate test is positive, and the high-temperature magnetization component in the rocks of the Katav Formation is primary.
