hrv Jezgra Moslavačke gore izgrađena je od S-tipa granita i granodiorita. Obavijena je migmatitima, a vanjsku zonu pretstavljaju metamorfiti amfibolskog facijesa. Moslavačka gora je produkt regionalnog metamorfizma donjopaleozojskog i starijeg pelitsko-psamitskog protolita. U sva tri tipa stijena mjestimice su uočene jače koncentracije minerala silimanita, andaluzita, kordijerita, granata i turmalina. U pegma-titskoj fazi formirano je niz lećastih tijela i žila metasomatsko-injekcijskih pegmatita s podređenim turmalinom, granatom i kvarcem čađavcem. Hidrotermalne kvarcne žice sa sulfidima su mineraloškog značaja. Za potrebe građevinarstva bili su otvoreni ili još rade kamenolomi granita, granitgnajsa, amfibolita, gabra i ortognajsa. Migmatiti i S-graniti izgrađuju središnje dijelove slavonskih planina. Namir-vestfalske su starosti, od 314 do 333 Ma. Metaklastiti nižih metamorfnih sekvenci sadrže palinomorfe silurske do donjokarbonske starosti. Regionalnim metamorfizmom formirana grafititna ležišta otkapana su u rudnicima Brusnik, Sivornica i Brezovo Polje u Psunju te u rudniku Kaptol u Papuku. Brojne metasomatsko-injekcione žile i tijela pegmatita otkapane su na lokacijama Veliki i Mali Debeljak, Točak, Bilo, Lom. Kvarcne žile su vađene u Zavlaci i Motičini Gornjoj. Za postkolizione I-granite vezan je volastonitski skarn u Kišeljevačkom potoku. Za dijabaze vezane su mineraloške pojave hematita, bakra, pirita i azbesta. Talk-kloritni škriljavci vađeni su u rudniku Koprivna na Psunju. Višegodišnja intenzivna istraživanja sedimentnih pojava urana u Radlovačkoj formaciji Papuka nisu dala pozitivne rezultate. Najznačajnije pojave nađene su u potocima Kaptol, Cipalovac i Ninkovac. U području slavonskih planina bili su otvoreni ili još rade kamenolomi granita, amfibolita, dijabaza i permotrijaskih kvarcita. U aluvionima brojnih potoka nađene su značajnije količine zlata, šelita, monacita, rutila, cirkona.

eng Core of the Moslavačka Mt. is built of S-type granite and granodiorite, wrapped up in migmatites. Outer zone is represented with metamorphites of amphibolite facies. The Moslavačka Mt. is a product of regional metamorphism on Lower Paleozoic pelito-psammitic protholite. Numerous quarries exploited granite, amphibolite, gabbro, orthogneiss. Stronger concentrations of sillimanite, andalusite, cordierite, garnet, and tourmaline were observed in different types of rocks. The pegmatite phase generated veins and irregular boddies of metasomatic-injected pegmatites with garnet and tourmaline. Hydrothermal quartz veinlets with sulphides have only mineralogical significance. Migmatites and S-granites form central parts of the Slavonian Mts. Dating gave age of 314-333 Ma (Namurian-Westphalian). Metaclastites of lower metamorphic sequences contain palynomorphs from Silurian to the Lower Carboniferous. Graphitite deposits generated by regional metamorphism were exploited in the mines Brusnik, Sivornica and Brezovo Polje in the Psunj Mt. and in the mine Kapitol in the Papuk Mt. Numerous metasomatic injected pegmatites were exploited on the locations Veliki and Mali Debeljak, Točak, Bilo, Lom and quartz veins at Zavlaka and Motičina Gornja. Postcollisional I-granites gave a small volastonite skarn deposit in the Kiseljevački brook. Mineralogical occurrences of hematite, pyrite, asbestos and copper are genetically bounded with diabases. Talc-chlorite schists were exploited in the mine Koprivna (Psunj). Longlasting investigations of sedimentary uranium occurrences were negative. The best results were obtained in the Kaptol, Cipalovac and Ninkovac brooks. In the alluvium of numerous brooks more significant quantities of gold, monazite, rutile, zircon and scheelite were found.
