Abstract

Cilj ovoga rada bio je opisati granitoidne stijene kamenoloma „Zebrato“, a prije svega njihove petrološke značajke. Granitoidne stijene Papuka na njegovom zapadnom dijelu većinom čine graniti i migmatiti (gnajsevi). Stijene su opisane na temelju mikroskopskih karakteristika, pomoću rezultata rendgenske difrakcije i proračuna provedenih softverom Perple_X. Na temelju rezultata analiza opisani su događaji iz geološke povijesti Papuka, tj. lokacije kamenoloma „Zebrato“. Mikrofizografske karakteristike stijena ukazuju da se radi o granitima i migmatitima koji su prema softverskim izračunima genetski povezani i nastali su istovremeno u sličnim uvjetima. Dobiveni su pseudopresjeci i vrijednosti solidusa koji je za obe stijene na 680°C. Na fenokristalu kalijskog feldspata iz migmatita rendgenskom difrakcijom analizirane su zone rasta, utvrđen je različit sastav zona i stupanj trikliničnosti K-feldspata u jezgri od 0,69 što je dalo uvid u moguće promjene uvjeta tijekom kristalizacije kristala i nastanka stijene domaćina. Sustav se sve sporije hladio. Uz dobivene rezultate dan je i pregled dosadašnjih istraživanja tog područja.

Abstract (english)

The aim of this paper was to describe the granitoid rocks of the "Zebrato" quarry, and above all their petrological characteristics. The granitoid rocks of Papuk in its western part are mostly granites and migmatites (gneisses). The rocks were described based on microscopic characteristics, using X-ray diffraction results and calculations performed with Perple_X software. Based on the results of the analysis, events from the geological history of Papuk, ie the location of the "Zebrato" quarry, are described. The microphysiographic characteristics of the rocks indicate that they are granites and migmatites that, according to software calculations, are genetically related and formed simultaneously in similar conditions. Pseudosections and solidus values for both rocks at 680 ° C were obtained. On the phenocrystal of potassium feldspar from migmatite, different growth zones were analyzed by X-ray diffraction, the composition of the zones and the degree of triclinicity of K-feldspar from the core was determined 0,69 which provided insight into possible changes in conditions during crystallization of the crystal and the formation of the host rock. The system cooled more and more slowly. In addition to the obtained results, an overview of previous research in the area is given.
