『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.』
