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.

Stratovolcanoes in the Western Cordillera – Polish Scientific Expedition to Peru 2003–2012 reconnaissance research
(2014) Gałaś, Andrzej; Panajew, Paweł; Cuber, Piotr Krzysztof
The Polish Scientific Expedition has been carrying out research in the Colca Canyon and the Valley of the Volcanoes (South Peru) since 2003. The National Park project, covering the mentioned areas, is the main purpose of the research. The extent and genesis of the Quaternary volcanic Andahua group is the leading theme of the investigation. The study area is surrounded with numerous Pliocene and Pleistocene stratovolcanoes: Ampato (6,288 m a.s.l.), Chachani (6,057 m a.s.l.), multi-cone Coropuna (6,425 m a.s.l.) and others. Some of them are still active, such as Misti (5,822 m a.s.l.) or Sabancaya (5,967 m a.s.l.) and pose a real hazard to the local population. In 2003–2012, the participants of the Polish Scientific Expedition climbed several times on volcanic peaks, gaining new experience and comparative samples for study.

Stratovolcanoes on the Chilean-Bolivian border as geoatraction
(Wydawnictwa AGH, 2020) Panajew, Paweł; Gałaś, Andrzej
The cluster of stratovolcanoes located on the Chilean-Bolivian border, in the Western Cordillera, is composed of typical, for that part of the Central Volcanic Zone in the Andes, volcanic landforms. The highest volcano is the Nevado Sajama (6,542 m a.s.l.), apparently extinct. The other: Parinacota (6,336 m a.s.l.), Pomerape (6,222 m a.s.l.), Acotango (6,052 m a.s.l.) and Cerro Quisiquisini (5,542 m a.s.l.) were all active in both the Pleistocene and the Holocene. Recently, only the Guallatiri Volcano (6,071 m a.s.l.) is still active. The summits of these mountains are covered with permanent snow or ice caps. On the slopes, there are post-glacial valleys, rocks glaciers and debris avalanches. In the vicinity of volcanic cones, active fumaroles occur, along with hot springs, geysers and high-mountain peat bogs (bofedales), in addition to one of the highest in the world mountain lakes - the Lago Chungará (4,520 m a.s.l.). The unique landform is a huge debris avalanche and was formed during the eruption of the Parinacota Volcano. Small villages settled by Aymara Indians and their cultural monuments complete the extraordinary landscape of the Altiplano Plateau. The values of biotic nature are also unique and deserving of protection on both sides of the state border. Moreover, these sites have been registered into the UNESCO World Heritage List. Modest accommodation facilities located off the main roads satisfy the qualified tourists interested in volcanology. The authors describe the grueling trekking trails, the climbing routes leading to the summits of volcanoes and the other geoattractions, accessible for ordinary hikers.
