Item type:Article, Access status: Open Access , Zarys budowy geologicznej Kordyliery Zachodniej południowego Peru(Wydawnictwa AGH, 2008) Paulo, AndrzejTremendous cross section of lithosphere is exposed in the walls of Rio Colca Canyon 120 km long and 1-3 high. Rio Colca begins at the edge of Altiplano and on the way to Pacific incises deeply into the Western Cordillera, then builds vast dejection cone at its foothills covering metamorphic Arequipa massif. Western Cordillera forms the most elevated horst of this segment of the Andes surmounted by dozens of huge stratovolcanoes. It is largely built of epicontinental Jurassic and Cretaceous formations, volcanic and detritic continental Cenozoic formations, and several Upper Cretaceous - Neogene intrusions. Pre-Pliocene strata are folded. Five compressive phases since Late Creataceous differing by azimuth of fold axes, strong uplift since Late Miocene and relevant fractures filled in part by ore veins and volcanic necks evidence rotation of the regional strain field.Item type:Article, Access status: Open Access , Idea ochrony Kanionu Colca i Doliny Wulkanów(Wydawnictwa AGH, 2008) Gałaś, Andrzej; Paulo, AndrzejDevelopment of tourism and related infrastructure in the Rio Colca Canyon region endangers environment of this deepest canyon worldwide. There is urgent need of balancing landuse development by protection of the most valuable areas and proving their importance to the world heritage of nature. Studies performed by the Polish Scientific Expedition to Peru since 2003 are aimed at project of the Canyon Colca and Valley of Volcanoes National Park. This park should protect a unique section of the orogenic belt 100 km long and 1-3 km high, magnificient landscape, sets of active faults, volcanoes, hot springs and specific wildlife including the largest condor habitat in the Andes. New park would strenghten the state protected areas system in the Arequipa department, increase its tourist attractiveness and determine constraints of regional development. Local authorities show great interest in developing the project.Item type:Article, Access status: Open Access , Ruda żelaza z dawnych kopalń pod Bobrowcem (Tatry Zachodnie)(Wydawnictwa AGH, 2006) Paulo, Andrzej; Panajew, PawełAn 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.Item type:Article, Access status: Open Access , Górnictwo i inne inwestycje w sąsiedztwie Kanionu Colca(Wydawnictwa AGH, 2008) Paulo, Andrzej; Gałaś, AndrzejEconomic and social environment of protected areas have crucial importance to their establishing and performance. Several gold and silver mines currently operated by Buenaventura and Hochschild to the north of Rio Colca Canyon and the Valley of the Volcanoes stimulate regional development and fulfill environmental standards. Mining leases cover more than 1500 km$^2$. Geological structure of ore deposits is given along with history, production activity, perspectives and sustainable management input of the mines. Mining camps may be adapted for housing of future visitors of National Park Colca Canyon and Valley of the Volcanoes. Water tunnels of Majes Project are not conflicting with nature protection and future Angostura dam and artificial lake shall enhance touristic assets. Socabaya - Mantaro power line negatively affects landscape and planned road Ayo - Huambo poses some doubts. Creation of geopark shall strengthen poor system of protected areas in Arequipa region.Item type:Article, Access status: Open Access , Problemy zagospodarowania wyrobisk po eksploatacji kruszywa naturalnego na przykładzie złóż w dolinie Soły między Kętami a Bielanami(Wydawnictwa AGH, 2005) Bobrek, Kamila; Paulo, AndrzejDeposits of the natural aggregates along the Soła valley were formed within Quaternary rendzina terrace. They are exploited from under the groundwater level. As a result, many hectares of valuable agricultural land are converted into post-mining pits, which change the natural environment of the Soła valley and preclude future crops. Being forced to declare post-mining redevelopment mode, users of the natural aggregate deposits declared construction of water reservoirs, which they call fishing ponds. However, in reality the ponds are used for recreation fishing but not for productive fish farming, which appears impossible, which cannot be drained in deep basins. A panorama of possible ways of reclamation of post-mining pits based on natural environment and social conditions is discussed, forming main body of the paper.
