The Transdanubian Range in Hungary comprises a series of blackshale-hosted Mn carbonate and cherty, Fe-rich Mn oxide mineralizations in association with varicoloured metalliferous clays. The Úrkút manganese mineralization is among the largest deposits in the world in its class. Its current reserve is 80 millions tons of Mn carbonate ore. In spite of its Jurassic age, the original features of the deposit were overprinted only by diagenesis.

Austria's magnesite industry is of worldwide importance. The majority of the Austrian magnesite deposits are located in the Carboniferous series of the Eastern Greywacke Zone of the Eastern Alps. The Veitsch deposit is considered to be the type locality of "carbonate-hosted sparry magnesite deposits". Numerous siderite mineralizations of various sizes can be found in the Early Palaeozoic rock series of the Eastern Greywacke Zone. Presently only the Erzberg siderite deposit, situated in the province of Styria, is operating and is the symbol of mining in Austria. The siderite ore body is hosted by fine-grained limestones of Devonian age; metasomatic-epigenetic structures are dominant. The proposed genetic models of the fundamental mechanisms of carbonate mineralization are still a matter of debate.
