Abstract

Ovim diplomskim radom obuhvaćene su Prominske naslage na području Maslenice u sjevernoj Dalmaciji. Na navedenom području naslage su uglavnom izgrađene od vapnenačkih konglomerata, kalkarenita i vapnenaca. Naslage su dobro otkrivene i relativno slabo poremećene, tako da je njihova analiza omogućila interpretaciju facijesa, facijesnih asocijacija, određivanje površina poplavljivanja i površina forsirane regresije, što je poslužilo za interpretaciju taložnih okoliša i relativnih promjena razine mora u ovom dijelu Prominskog bazena. Proučavane naslage taložene su u sjeveroistočnom dijelu Novigradskog sub-bazena u okolišima padina lepeznih delti, šljunčanim plažama, obalnom licu, prijelaznoj zoni i distalnijim okolišima gdje je bila moguća biogena karbonatna sedimentacija. Površine poplavljivanja i površine forsirane regresije ukazuju na česte promjene relativne razine mora, koje su najvjerojatnije bile uvjetovane tektonikom uslijed izdizanja Dinarskog orogena i razvoja Dinarskog predgorskog bazena.

Abstract (english)

This thesis encompasses the Promina beds in the area of Maslenica in northern Dalmatia. In this area the sedimentary succession mostly comprises carbonate conglomerates, calcarenites and limestones. The succession is well-exposed and relatively undisturbed, which enabled the interpretation of facies, facies associations, determination of flooding surfaces and surfaces of forced regression, which served to interpret depositional environments and relative changes of sea level in this part of the Promina basin. The studied sedimentary succession was deposited in the north-eastern part of the Novigrad sub-basin in a range of depositional environments, which include fan delta slopes, gravel beaches, shoreface zone, offshore-transition zone and more distal environments where biogenic carbonate sedimentation was possible. Flooding surfaces and surfaces of forced regression indicate frequent relative changes of sea level, which were probably caused by tectonics due to the uplift of the Dinaric Orogen and the development of the Dinaric Foreland Basin.
