Abstract

U diplomskom radu analizirana su tri uzorka tufa s neposrednim podinama i krovinama s lokaliteta Bukova glava na Krndiji. Rezultati mineraloških i geokemijskih istraživanja pokazali su kako sva tri tufa pripadaju neutralnoj seriji stijena, a kao izvor vulkanizma pretpostavljen je aktivni kontinentalni rub u sjeverozapadnim i središnjim Istočnim Karpatima. Prema fosilnoj zajednici iz podinskih i krovinskih naslaga, relativna starost prvog i trećeg tufa je kasnobadenska, s tim da je treći tuf taložen na granici sa sarmatom, dok je četvrti tuf sarmatske starosti. Prvi tuf je taložen u dubljevodnim marinskim okolišima, a tendencija oplićavanja vidljiva je u okolišu taloženja trećeg tufa da bi se četvrti tuf taložio u plitkovodnim okolišima reduciranog marinskog saliniteta.

Abstract (english)

In this paper three tuff samples were anlaysed with underlying and overlying beds from Bukova glava locality on Mt. Krndija. The results of mineralogical and geochemical analyses have shown that all three tuffs belong to neutral rock series and volcanism source is presumed to be active continental margin in the northwest and central East Carpathians. Due to the fossil record in underlying and overlying beds, the relative age of the first and third tuff is determinated as Late Badenian, while the third tuff was deposited on the border with Sarmatian, and the relative age of the fourth tuff is Sarmatian. The first tuff was deposited in deep-water marine environment. The shallowing tendency is visible in the third tuff depositional environment while the fourth tuff was deposited in shallow marine environment of reduced salinity.
