Abstract

Cilj ovog rada bio je istražiti geološku građu okolice Skrada na temelju površinskih geoloških
podataka u mjerilu 1:20.000. Područje istraživanja izgrađuju naslage permske, trijaske i jurske
starosti. Današnji strukturni odnosi između litostratigrafskih jedinica izuzetno su kompleksni, a
uvjetovani su trima glavnim tektonskim fazama. Najstariju fazu obilježava navlačna tektonika
kojom su alohtone naslage permske i trijaske starosti dovedene u strukturni položaj iznad
autohtonih naslaga glavnog dolomita noričko–retske starosti te izmjene dolomita i vapnenaca
donjo- i srednjejurske starosti. Nakon navlačne faze nastupila je faza ekstenzijske tektonike koja je
razlomila navlaku, a ujedno i otkrila podinu navlake u tektonskom oknu u kanjonu potoka Jasle i
Curak. Najmlađa tektonska faza obilježena je kompresijskom tektonikom koja je autohtoni
noričko–retski dolomit dovela u strukturni položaj iznad donjojurskih karbonata. Uz geološku kartu
u mjerilu 1:20.000 s pripadajućim profilima, načinjen je geološki 3D model i interaktivni GIS
projekt koji pruža mogućnost dopune i korekcije podataka, kao i pregled svih podataka
obuhvaćenih terenskim istraživanjima.

Abstract: The goal of this thesis was to thoroughly investigate Skrad area based on surface data that were
collected in the course of geological mapping in 1:20.000 scale. The research area is built out of
clastic and carbonate deposits of Permian, Triassic and Jurassic age. The present-day structural
relations between the litostratigraphic units are complex due to three tectonic phases. The oldest
phase is characterised by thrust faulting that resulted in allochthonous (nappe) position of Permian
and Triassic above autochthonous Triassic and Jurassic deposits. The second phase is characterised
by extension accommodated by normal faulting, which resulted in breaking apart of the nappe
contact and opening of tectonic window located in the canyon of Curak and Jasle streams. The last
tectonic phase is characterised by reverse faulting which enabled uplift of the autochthonous
Norian and Rethian Hauptdolomite in structural position above lower Jurassic carbonates. In this
thesis, beside the geological map in 1:20.000 scale accompanied by geological cross-sections, the
geological 3D model and interactive GIS project have been made, too. The latter provides a
possibility to manipulate with collected data and also to incorporate new data from future studies.
