Abstract
High-grade iron ores and bauxites of the Kursk magnetic anomaly (KMA) were formed in weathering crusts on the Early Precambrian ferruginous quartzites and shales, i.e., banded iron formation (BIF). Thus far, weathering crusts on the BIF were considered separately, although they formed simultaneously and represent a single sequence in each ore region. Therefore, it is of great interest to compare the coeval weathering crusts on rocks of the formation under consideration for a complex prediction of high-grade iron ores and bauxites. The obtained results showed that the BIF-hosted iron ores were formed during all stages of crust formation in the Paleozoic and such ores can be predicted throughout the KMA, whereas bauxites were only formed in inter-ore shales on the southwestern flank of the anomaly.
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.
