    Ruda żelaza z dawnych kopalń pod Bobrowcem (Tatry Zachodnie)
    (Wydawnictwa AGH, 2006) Paulo, Andrzej; Panajew, Paweł
    An enigmatic iron ore which was exploited on the southwest slopes of Bobrowiec in the Western Tatra Mountains at the early XIX century, was described for the first time. It consists mainly ot hematite, goethite, and lepidocrokite cementing fine grained Lower Triassic sandstones and mudstones or forming secondary veinlets. The iron hydroxides and oxide appear as secondary minerals. They form gossan and tectonically remobilization veinlets, resulting from thrusting Kriżna unit against High Tatric autochthon. Primarily iron was probably deposited in the form of thin sulphide lens along with silty-clay sediments in an isolated euxinic basin. The ore contains roughly 30% Fe. New light on the genesis of iron ores and facies within sedimentary series of Lower Triassic in the Tatra is thrown.
