Abstract
A new occurrence of phosphate mineralization (Shankinka) has been explored in the Fedkovskaya River mouth, Ruza district, Moscow region. The most common mineral phases are delvauxite, mitridatite, fluorapatite, and crandallite. The Fe–Ca–Al phosphate occurrences in the region are associated with the Bajocian–Bathonian paleovalleys embedded in Carboniferous rocks and partially filled with Callovian sediments. The structural features of the phosphatization zone along with its enrichment with Co, Ni, Zn, Cu, and REE indicate a possible link between the overlying Oxfordian sediments and phosphate mineralization. The epigenetic phosphate mineralization can be related to the seepage of phosphorus-rich interstitial waters released from the Oxfordian organic-rich sediments into the underlying Callovian friable rocks enriched with Fe minerals.
期刊介绍：
Lithology and Mineral Resources is an international peer reviewed journal that publishes articles on a wide range of problems related to the formation of sedimentary rocks and ores. Special attention is given to comparison of ancient sedimentary rock and ore formation with present-day processes. The major part of the journal is devoted to comparative analysis of sedimentary processes on the continents and in oceans, as well as the genetic aspects of the formation of sedimentary and hydrothermal–sedimentary mineral resources. The journal welcomes manuscripts from all countries in the English or Russian language.
