Abstract

U ovom radu analiziran je uzorak pješčenjaka poznat pod nazivom Maceljski
pješčenjak. Radi se o pješčenjacima donjomiocenske starosti koji pripadaju formaciji Macelj.
Uzorkovan je izdanak kod sela Donji Macelj u Hrvatskom zagorju. Analizom sadržaja
karbonatne komponente utvrđeno je da pješčenjak ne sadrži karbonatne minerale. Analiza
mikroskopskog izbruska pokazala je da se radi o srednje do dobro sortiranom gusto
pakiranom srednjezrnatom pješčenjaku u čijem sastavu dominiraju kremen i litične čestice.
Osim toga pješčenjak sadrži i brojne čestice glaukonita koje stijeni daju karakterističnu
zelenu boju. Uzorak je određen kao litični arenit s glaukonitom.

Abstract (english)

In this paper, a sandstone sample known as Macelj sandstone is analyzed. These
sandstones are of Early Miocene age that belong to the Macelj Formation. Sampling was
done near the village of Donji Macelj in Hrvatsko Zagorje. Analysis of the content of the
carbonate component revealed that the sandstone does not contain carbonate minerals.
Analysis of the thin-sections showed that it is a medium to well-sorted densely packed
medium-grained sandstone composed of quartz and lytic particles. The sandstone contains
also numerous glauconite particles that give the rock its characteristic green colour. The
sample was determined as lytic arenite with glauconite.
