Abstract

Viviparus naslage predstavljaju klastične sedimente koji su tijekom pliocena i početkom pleistocena, odnosno regionalnog kata cernikij, taložene u jugozapadnom dijelu Panonskog bazenskog sustava (PBS). Cilj ovog rada bio je analizom granulometrijskog sastava sedimenata, rendgenskom difrakcijskom analizom pelitnih sedimenata te analizom zajednice teških minerala pješčanog materijala utvrditi strukturne značajke, mineralni sastav i porijeklo klastičnog detritusa Viviparus naslaga Banovine. Dobiveni rezultati pokazuju da se radi o loše sortiranom, strukturno nezrelom detritusu. U zajednici teških minerala prevladavaju opaki minerali, a među prozirnim teškim mineralima najzastupljeniji su granati te rezistentni minerali poput cirkona, rutila i turmalina. Strukturne značajke detritusa ukazuju na njegovo lokalno porijeklo, a njegov sastav ukazuje na porijeklo detritusa iz starijih sedimentnih i kiselih magmatskih stijene. Izvorišna područja najvjerojatnije su bila lokalna izdignuta područja unutar JZ dijela PBS-a i rubna područja Dinarida.

Abstract (english)

Viviparus deposits are clastic sediments that were deposited in the southwestern part of the Pannonian Basin system during the Pliocene and the beginning of the Pleistocene, in the regional floor Cernikij. The aim of this study was to determine the structural characteristics, mineral composition and origin of clastic detritus Viviparus deposits of Banovina by analysis of granulometric composition of sediments, X-ray diffraction analysis of pelitic sediments and analysis of the community of heavy sand minerals. The obtained results show that it is a poorly sorted, structurally immature detritus. The heavy minerals community is dominated by opaque minerals, and among the transparent heavy minerals, garnets and resistant minerals such as zircon, rutile and tourmaline are the most common. The structural features of detritus indicate its local origin, and its composition indicates the origin of detritus from older sedimentary and acidic igneous rocks. The source areas were most likely local uplifted areas within the SW part of the PBS and the marginal areas of the Dinarides.
