Abstract

U radu je analiziran granulometrijski sastav i sastav lake mineralne frakcije dva uzorka pjeskovito siltoznih sedimenata gornjomiocenske starosti s lokaliteta Bozara nedaleko od Velike na južnim obroncima Papuka. Uzorak Bzr 1 određen je kao vrlo loše sortirani pjeskoviti silt kod kojeg u sastavu lake mineralne frakcije prevladavaju muskovit i karbonatne čestice, a u značajnoj mjeri zastupljene su čestice stijena i kvarc. Uzorak Bzr 2 također je određen kao vrlo loše sortirani pjeskoviti silt. U... More njegovom sastavu najzastupljenije su karbonatne čestice, a značajno su još zastupljene čestice stijena i kvarc. Vrlo loša sortiranost analiziranih uzoraka ukazuje da se radi o strukturno nezrelom materijalu, a bogata zastupljenost karbonatnih minerala i nizak udio kvarca pokazatelj su mineralne nezrelosti sedimenta. Strukturna i mineraloška nezrelost analiziranih sedimenata pokazatelj je njihovog lokalnog porijekla što ih razlikuje od većine gornjomiocenskih pijesaka iz jugozapadnog dijela Panonskog bazena za koje je utvrđena alpska provenijencija.

Abstract (english)

The granulometric composition and the composition of the light mineral fraction of two samples of sandy-silty sediments of the Upper Miocene from the Bozara locality near Velika on the southern slopes of Papuk were analyzed. Sample Bzr 1 was determined to be a very poorly sorted sandy silt in which the light mineral fraction is dominated by muscovite and carbonate particles. Rock particles and quartz are also present to a considerable extent. Sample Bzr 2 was also determined to be a very... More poorly sorted sandy silt. Carbonate particles are most strongly represented in its composition, and rock particles and quartz are also present to a considerable extent. The very poor sorting of the analyzed indicates that it is a structurally immature material, and the abundant presence of carbonate minerals and the low proportion of quartz are indicators of the mineral immaturity of the sediment. The structural and mineralogical immaturity of the sediments is an indicator of their local origin, which distinguishes them from the majority of Upper Miocene sands from the southwestern part of the Pannonian Basin, for which an Alpine origin has been established.
