Abstract

Izdanci psunjskog metamorfnog kompleksa u istoĉnim dijelovima Papuka
sadrţe/izgraĊeni su od granat-staurolitnih tinjĉevih škriljavaca. Pojava tih minerala
omogućava u povoljnim sluĉajevima rekonstrukciju p-T-metamorfnog puta, a kod
nepovoljnih paragenetskih okolnosti odreĊivanje vršnih uvjeta metamorfizma. Primjenom
petrografske analize pomoću polarizacijskog mikroskopa, analize mikrostrukturnih odnosa i
odreĊivanjem kemijskog sastava minerala i cjelostijenske kemije, modelirani su p-T-uvjeti
metamorfizma. Ti su uvjeti dobiveni klasiĉnim geotermobarometrima i primjenom izrade
pseudopresjeka u višekomponentnom kemijskom sustavu. Unutar pseudopresjeka
konstruirane su izoplete i izomode pojedinih minerala. Dobivene su tako vrijednosti tlaka od
4.976 kbar, a temperature 529 ℃, potvrĊene svima korištenim metodama.

Abstract (english)

Psunj metamorphic complex outcrops from eastern part of Papuk are made of garnet-staurolite-mica schists. Appearance of these minerals enables reconstruction of p-T metamorphic path in favorable conditions and in unfavorable paragenetic conditions assessment of metamorphic peak conditions. Modeling of metamorphic p-T conditions was successful by applying petrographic analysis using polarizing microscope, using microstructural relations and determination of chemical composition and whole-rock chemistry. This conditions are determined by using classical geothermobarometers and by applying pseudosection construction in chemical systems with a few components. Isopleths and isomodes of some minerals in pseudosections are constructed, too. Determined values of pressure and temperature are 4.976 kbar and 529 ℃. All methods confirmed them approximately.
