Abstract

Tema ovog rada je provenijencija pješčenjaka uzorkovanih na izdancima
dubokomorskih naslaga kredne i paleocenske starosti sa područja Banovine. Metodom
kvantitativne analize teških frakcija pomoću polarizacijskog mikroskopa prouceno je podrijetlo
siliciklastičnog detritusa u pješčenjacima kredne i paleocenske starosti. Teška mineralna frakcija
ovih pješčenjaka sastoji se od apatita, cirkona, turmalina, rutila i različitih količina Cr-spinela.
Pješčenjaci su dominantno su sastavljeni od kvarca, sedimentnih i metamorfnih čestica vrlo
niskog do niskog stupnja, zajedno s mafičnim litičnim česticama. Sastav mastrihtskih
pješčenjaka vjerojatno odražava eroziju ekshuiranih dijelova kore u kolizijskoj zoni. Porijeklo
detritusa u paleocenskim pješčenjacima vjerojatno je bilo povezano s erozijom magmatskog luka
koji je nastao duž područja subdukcije jadranske ploče ispod Europe, kao i metamorfnih jedinica
ekshumiranih u akrecijskom klinu i / ili eventualno iz jedinica Tisza ploče.

Abstract (english)

The topic of this paper is the provenance of sandstones sampled on the outcrops of
deep-sea Cretaceous and Paleocene ages from the Banovina area. The origin of siliciclastic
detritus in Cretaceous and Paleocene sandstones was investigated by quantitative heavy fraction
analysis using a polarization microscope. The heavy mineral fraction of these sandstones is
composed of apatite, zircon, tourmaline, rutile and various amounts of Cr-spinel. The sandstones
are predominantly composed of quartz, sedimentary and metamorphic particles of very low to
low grade, together with mafic lithic particles. The composition of the Maastrichtian sandstones
probably reflects the erosion of exhumed kontinental units in the collission zone. The origin of
detritus in the Paleocene sandstones was probably related to the erosion of the igneous arch that
occurred along the subduction zone of the Adriatic plate beneath Europe, as well as metamorphic
units exhumed in the accretionary wedge and / or possibly from Tisza plate units.
