Geological map of the Učka mountain peak area : master’s thesis

Cilj ovog diplomskog rada bio je istražiti geološku građu vršnog dijela Učke. Geološkim kartiranjem prikupljeni su podatci za izradu geološke karte mjerila 1:20.000. Kartirano je i opisano devet neformalnih litostratigrafskih jedinica. Jedinica Sis koja predstavlja prijelaz iz donje u gornju kredu; gornjokredne jedinice Milna, Sveti Duh, Gornji Humac te nedefinirane jedinice u ovom radu zvane Gornji kalcisferski vapnenac i Gornjosantonske naslage; paleogenske jedinice Foraminiferski vapnenci te Prijelazne naslage i najniži dio fliša te kvartarne naslage. U radu je potvrđeno da je južni vršni dio Učke u navlačnom kontaktu s podlogom, ali sjeverna granica navlačne strukture nije precizno određena. Utvrđeni su nalazi foraminiferskih vapnenaca na lokacijama na kojima prethodnim istraživanjima nisu izdvojene. Konstrukcijom geoloških profila procijenjena je debljina jedinica Gornji kalcisferski vapnenac i Gornjosantonske naslage. S ciljem prikaza geoloških odnosa u dubini konstruirano je jedanaest geoloških profila.The goal of this thesis was to investigate the geological seting of the Učka mountain peak area. The data for the construction of a geological map in 1:20.000 scale were acquired using geological mapping methods. Nine informal lithostratigraphic units were mapped and described. Unit Sis represents a transition from the Lower to the Upper Cretaceous, Upper Cretaceous deposits are described as units Milna, Sveti Duh, Gornji Humac and up to now undefined units Upper Calcisphera Limestone and Upper Santonian Deposits, Palaeogene units comprise Foraminifera Limestone and Transitional Deposits, while Quarternary Deposits include rockfall deposits. The thesis confirms that the southern part of the Učka peak area represents a thrust over underlying deposits, but the northern part of the thrust structure is still not precisely located. Foraminifera Limestone outcrops were found on the locations that were not previously mentioned. The thickness of the Upper Calcisphera Limestone and Upper Santonian deposits were estimated from constructed geological profiles. For the purpose of discussion of geological relationships in depth, 11 geological profiles were made
