К проблеме петрогенезиса карбонат-тальковой толщи Кривбасса
В.В. Покалюк, В.Г. Яценко
Abstract
New evidence of the stratified volcanogenic nature of metaultrabasites of
the talcous subsuit of the Early Pre-Cambrian Kryvorizhsky metamorphic
series has been obtained. A group of sedimentary volcanic-terrigenous rocks
(meta-aleuropelites) synchronous and closely connected with ultrabasic
volcanicity are petrochemically diagnosed. By a degree of enrichment of
these meta-aleuropelites with Fe, Mg, Ca, Cr components, they form a
progressive series from ordinary low-ferrous-magnesia aluminiferous phyllite
of the Skelevatskaya suite to anomalous high-ferrous-magnesia differences
enriched with calcium and chromium approaching ultrabasites of the talcous
horizon to a greater or lesser extent.
