Оn the age, genesis, and mineralogy of the Kaspa Formation (south of the Krasnoyarsk Region)

Polygenetic deposits of the Kaspa Fm. are widespread within the Minusinsk depressions and their mountain border in the southern part of the Krasnoyarsk Region. They have been studied by many geologists during geological surveys and exploration. Slope rocks, which are considered to be products of re­deposition of areal and linear weathering crusts, lacustrine-alluvial and polygenetic deposits of complex genesis were included in this formation. The interest in studying the formation deposits is caused by the regular revision of the lower Quaternary boundary; therefore, researchers of the Quaternary pay particular attention to the investigation of the Lower Quaternary sediments. In addition, some prospects for bauxite - and manganese-bearing deposits are associated with sediments of this formation, and in areas of gold placers, with gold potential.
