Abstract
U sklopu izrade ovog diplomskog rada prikupljeni su, analizirani i interpretirani novi strukturni podaci o borama i rasjedima na jugoistočnom dijelu otoka Paga u Sjevernoj Dalmaciji. Na temelju strukturne analize rasjeda, izdvojene su grupe rasjeda po kriteriju njihove kinematske kompatibilnosti. Za svaku grupu rasjeda određen je režim paleonaprezanja, izračunat orijentacijom glavnih osi paleonaprezanja. Korištene su dvije metode: P B T axes (P–T metoda) i Right dihedron (NDA) metoda unutar programskog paketa Win–Tensor. Izdvojeno je pet grupa rasjeda koje su interpretirane, određen im je režim paleonaprezanja, te su stavljene u vremenski kontekst. Najstariji su interpretirani rasjedi grupe 5 koju čine reversni rasjedi pružanja SZ–JI, nastali u kompresijskom režimu paleonaprezanja krajem eocena i početkom oligocena, što odgovara glavnoj kompresijskoj fazi u Vanjskim Dinaridima. Rasjedi grupe 4 također predstavljaju reversne rasjede, pružanja SI–JZ. Nastali su u kompresijskom polju naprezanja s pružanjem glavne kompresijske osi I–Z, dok se za vrijeme aktivnosti ove grupe rasjeda pretpostavlja oligocen–miocen. Grupu 3 predstavljaju reversni rasjedi pružanja ZJZ–ISI, uz pružanje glavne kompresijske osi u pravcu SSZ–JJI. Vremenska aktivnost ove grupe rasjeda se također pretpostavlja kao oligocen–miocen. Rasjede unutar grupe 2 predstavljaju normalni rasjedi s translacijom krovinskih krila prema sjeveru i sjeveroistoku. Pružanje tenzijske osi je po pravcu S–J, dok se vrijeme nastanka ovih rasjeda pretpostavlja kao miocen–pliocen. Grupu 1 čine rasjedi pružanja S–J, s izraženim lijevim karakterom pomaka, nastali u transpresijskom režimu naprezanja tijekom kraja pliocena i kvartara. Na temelju provedene strukturne analize orijentacije slojevitosti unutar gornjokrednih naslaga opisane su dvije bore. Zaključeno je da su bore obilježene uspravnima osnim plohama (kuta nagiba 87–88°) pružanja SZ–JI. Međukrilni kutevi bora variraju u rasponu od 131–135°, što odgovara blagim borama. Bore su u svojim sjeveroistočnim i jugozapadnim krilima rasjednute brojnim lijevim i desnim rasjedima, koji su zabilježeni i analizirani. Zbog sličnih strukturnih značajki, zaključeno je da su bore nastale unutar istog kompresijskog događaja, povezanog s glavnom kompresijskom fazom u Vanjskim Dinaridima.
Abstract (english)
Abstract: This diploma thesis included collecting, analyzing and interpretation of new structural data on folds and faults in the southeastern part of the island of Pag, northern Dalmatia. Based od structural analysis of faults, several fault groups were separated based on their kinematic compatibility. For each group of faults paleostress vectors and stress tensors were calculated. Two methods were used with the usage of the computer programme Win–Tensor, P B T axes (P–T method) and Right diedron (NDA) method. A total of five different groups of faults were separated, their paleostress regime analysed and time of their formation was established. The oldest were faults from the group 5, which are represented by reverse faults NW–SE strike, probably formed during the Late Eocene–Early Oligocene, connected with the main compressional phase of the Outter Dinarides. Group 4 faults are represented with reverse faults, with striking NE–SW. They indicate compressional stress field, with main compressional axis E–W directed, and activity in Oligocene– Miocene. Group 3 is represented with reverse faults with WSW–ENE strike, with direction of main compressional axis NNW–SSE. Temporal acitivity is interpreted as Oligocene–Miocene. Group 2 faults are comprimised of normal faults with movement of hanging wall towards N and NE. Main tension axis has N–S strike, while time activity is also presumed as Miocene–Pliocene. Group 1 faults comprise N–S striking faults with distinctive sinistral displacement, indicating transpressional regime presumed to be active during Late Pliocene and Quarternary. Based on structural analysis of the strata in Upper Cretaceous, two folds were described and analysed. Both are characterized by upright axial plane (with inclination of 87–88°) striking NW–SE. Measured values of interlimb angles of these folds range from 131–135°, indicating gentle folds. Folds are faulted by numerous sinistral and dextral faults in both northeastern and southwestern limb. Based on similar structural orientation, both folds were created during the same compressional event, connected with main compressional phase in the Outer Dinarides.
