The Slovak Ore Mountains (Slovak: Slovenské rudohorie, Hungarian: Gömör–Szepesi-érchegység, German: Slowakisches Erzgebirge or Zips-Gemer-Erzgebirge) are an extensive mountainous region of Slovakia's Spiš and Gemer region, and in small part in northern Hungary, within the Carpathians. It is the largest mountain range in Slovakia. In the geomorphological system, the Slovak Ore Mountains belong to the Inner Western Carpathians.
The mountains are bordered by Zvolen in the west, Košice in the east, the rivers Hron and Hornád in the north, and the Juhoslovenská kotlina and Košice Basin (Košická kotlina) in the south. The region includes the Domica Cave (jaskyňa Domica), one of the biggest caves in Europe, Zádiel canyon and Krásna Hôrka Castle.
Geomorphologically, the Slovak Ore Mountains are grouped within the Inner Western Carpathians. The mountains do not have a central ridge - they consist of several independent sections, geomorphological regions:
The Ore Mountains/ɔːr/ (German: Erzgebirge; Czech: Krušné hory; both literally "ore mountains") in Central Europe have formed a natural border between Saxony and Bohemia for around 800 years, from the 12th to the 20th centuries. Today, the border between Germany and the Czech Republic runs just north of the main crest of the mountain range. The highest peaks are the Klínovec (German: Keilberg), which rises to 1,244 metres (4,081 ft) above sea level and the Fichtelberg (1,215 metres (3,986 ft)).
The area played an important role in contributing Bronze Age ore, and as the setting of the earliest stages of the early modern transformation of mining and metallurgy from a craft to a large-scale industry, a process that preceded and enabled the later Industrial Revolution.
The Ore Mountains are a Hercynian block tilted so as to present a steep scarp face towards Bohemia and a gentle slope on the German side. They were formed during a lengthy process:
During the folding of the Variscan orogeny, metamorphism occurred deep underground, forming slate and gneiss. In addition, granite plutons intruded into the metamorphic rocks. By the end of the Palaeozoic era, the mountains had been eroded into gently undulating hills (the Permian massif), exposing the hard rocks.
