Serpentinite in the Śnieżnik Massif: petrology and ecological impact


The paper presents a locality related to the occurrence of serpentinite body from the western slope of Żmijowiec in the Śnieżnik Massif. On the basis of field observations and numerous literature references, I provide a detailed geological description of this site and discuss the origin and tectonic settings of the serpentinite body. Apart from compelling geology, these rocks are site for ladder spleenwort, a rare species protected in Poland as well as in the European Union.
