The Serpukhovian Stage in the Verkhnyaya Kardailovka section, South Urals

Stratigraphy and Geological Correlation, 2010
The paper describes a Serpukhovian Stage section, exposed along the Ural River near the village of Verkhnyaya Kardailovka (Bashkortostan). The section is uniquely complete and is proposed as a GSSP candidate for the base of the Serpukhovian. The Upper Visean and Serpukhovian beds are represented by relatively deep facies, which contain ammonoids ...

Origin of vitriol Lake Gay, South Urals

International Geology Review, 1967
This paper can be considered a case history in which geology, geophysics, and more particularly geohydrology and geochemistry, when applied to the problem of origin of a vitriol lake, led to discovery of a copper prospect. After a review of various postulated origins for the vitriol lake and previous interpretation of the local structure, new evidence ...
