title: Kerch ironstones as unconventional Nd and MREE resources:&#x0D;features and prospects
abstract: Based on the mineralogy and major and trace element&#x0D; composition (including REE+Y) of bulk samples&#x0D; and in separate size fractions of the ore, the contribution&#x0D; of different REE+Y species to the total REE budget of&#x0D; ironstones from the Kamysh-Burun trough was estimated.&#x0D; Kerch ores have the structure of REE+Y accumulation&#x0D; typical for marine sedimentary iron ore deposits.&#x0D; Light REEs form independent mineralization of authigenic&#x0D; phosphates (rhabdophane-ty
