Abstract

Glavni cilj ovog diplomskog rada bio je usporediti recentne dravske sedimente sa sedimentima na lokalitetu Novigrad Podravski te im utvrditi porijeklo. U tu je svrhu obiđen i snimljen teren, uzorkovani su šljunci i pijesci te su napravljene granulometrijska i petrografska analiza te analiza teške mineralne frakcije. Rezultati petrografske analize i analize teških minerala ukazuju da porijeklo recentnih sedimenata rijeke Drave i četvrte dravske terase (pleistocen) odgovara geologiji istočnih... More Alpa koje su građene od neoproterozojskih i fanerozojskih metamorfnih stijena. Sastav valutica ukazuje i na prisutnost vulkanskih stijena u izvorišnom području. Ne isključuje se mogućnost da je dio materijala četvrte dravske terase pretaložen s okolnih gora čije je uzdizanje započelo u pliocenu, što je potkrijepljeno većom zrelošću teške frakcije te povećanim udjelima epidota, cirkona, rutila i turmalina u pojedinim uzorcima.

Abstract (english)

The main goal of this Thesis was to compare recent Drava river sediments with sediments of Novigrad Podravski and determine their provenance. For that purpose river and excavation sites were visited and surveyed where gravel and sand were sampled. This was followed granulometric, petrographic and quantitative heavy mineral analysis. Results show that the recent Drava river sediments and the 4th Drava river terrace (Pleistocen) to some degree have similar characteristics, and are ultimately... More derived from a common source area in the Eastern Alps largely built of neoproterozoic and phanerozoic metamorphic rocks. Composition of pebbles indicates the presence of volcanic rocks in the source area. It is not not excluded that a part of 4th Drava river terrace sediments represent redeposited material from surrounding hills and mountains uplifted since the Pliocen, which is substantiated by the maturity of THM fraction and increased proportions of epidot group minerals, zircon, rutile and tourmaline in some specimens.
