IMPORTANCE OF OLISTOSTROME MEMBER FOR METALLOGENY OF LJUBIJA IRON ORE DEPOSITS
Ljubija mining area is built of more formations that belong to the Carboniferous, Permian, Triassic and Cenozoic. From all of these, only two are metalliferous to iron: Javorik formation with olistostrome member and Neogene-Quaternary of Prijedor basin. The first includes primary siderite and ankerite partially limonitised ore and in the second onl...
