Oticka sopka / Otice volcano


[CZ] Oticka sopka Oticka sopka je prirodni pamatka, ktera se rozprostira od zapadniho okraje obce Otice a na severni strani vrcholku Kamenna hora (310 m.n.m.), ktery se zveda zapadnim smerem od obce. Jihozapadnim smerem od vyse uvedene prirodni pamatky je oblast prirodni rezervace Hvozdnice. Severovychodnim smerem od obce Otice lezi mesto Opava a jiznim smerem mestecko Hradec nad Moravici. Prirodni pamatku Oticka sopka jak nazev napovida tvori pozustatek sopky, ktera pochazi z obdobi spodniho miocenu. Vychoz puvodni sopky, ktery tvori cedicova hornina byl objeven pod vrcholkem lomu na Kamenne hore. Vrcholek Kamenna hora tvori kulmske horniny, kterymi prostupuji na povrch neovulkanity. Stari mistniho pozustatku sopky stanovili odbornici na 20 milionu let. Krater na vrcholku sopky nebyl vytvoren pomoci prirodnich sil, ale vznikl v dusledku tezby v lomu v prvni polovine 20. stoleti. Ve zdejsim lomu byl zahajen provoz v roce 1890 a utlum tezby nastal v roce 1949. V odkryvech vidime podpovrchove ztuhly kanal, ktery zrejme byl privodnim zdrojem vulkanu. Steny lomu tvori cernoseda porovita hornina s drobnymi vyrustky olivinu a pyroxenu. Tuto horninu odbornici nazyvaji meliticky olivinicky nefelinit. V byvalem lomu hornina praska a v puklinach se objevuje svetly nazloutly karbonat. V dutinach pak muzeme videt krystalove druzy kalcitu a srostlice philipsitu. Tato oblast byla vyhlasena prirodni pamatkou v roce 1991 a na rozloze 10,44 hektaru. Lokalita se nachazi v nadmorske vysce 262 az 311 metru.Souradnice Vas zavedou na jedno misto oticke sopky.

Earthcaches include a set of educational notes and the details about where to find the location (latitude and longitude). Visitors to Earthcaches can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth.
