Реферат
The downwarpings in the Baltic sea are the model, explaining the mechanism of accumulation of carbonate-oxide ores. Microlaminated silts of downwarpings contain about 10 % of Corg and 12.9 % of Mn. Oxided Fe-Mn ores (concretions and crusts) are accumulating on 20-155 m depth, carbonatemanganic ores on 200-450 m depth. Carbonate-manganic silts have been compared with ancient carbonatemanganese ores. The conclusion has been done that these ores have been formed in similar sedimentative conditions.
Ключевые слова The Baltic sea, hydrosulfuric pools, manganese, iron, carbonate and oxide manganese ores, rhodochrosite.
