FIELD GEOLOGICAL WORKSHOP «PALEOZOIC ORGANIC BUILDUPS OF THE ILYCH RIVER BASIN, NORTHERN URALS»

Abstract

Colleagues from Ufa, Samara, Krasnoyarsk, Moscow and St. Petersburg visited the Ilych River (Northern Urals) on a geological field trip from June 26 to July 4, 2025. The choice of location was conditioned by the fact that in the Ilych River basin, outcrops of organic buildups of different types and ages are currently known, and there is also a favorable opportunity to see not only the organic buildups, but also the enclosing sediments. During these days, reefs of the Upper Ordovician, Upper Silurian and Lower Devonian, the Upper Serpukhovian-Lower Bashkirian microbial-brachiopod bank, Upper Carboniferous-Lower Permian biostromes, microbial and skeletal mounds were shown. Along with them, pre-reef, back-reef, and in some cases also sub-reef and over-reef sediments were presented.
