Abstract
It is shown that cooccurrences (parastereses) of chemical elements, minerals, sedimentary rocks, facies, and formations should be distinguished from their parageneses, which represent geological formations related to a single geological process. It has been established that phosphorus is concentrated in sedimentary manganese ores and is not accumulated in volcanosedimentary and hydrothermal deposits. Parageneses of Mn and P in sedimentary deposits are characterized. Parastereses of manganese ore and phosphorite-bearing facies in Oligocene rocks of southwestern Eurasia, Mesozoic and Upper Paleozoic sections of the Urals, and Mesozoic- Cenozoic sequences of Morocco are considered.
