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. During erzgebirge Radwanderkarte 1 : 100 000 PDF folding of the Variscan orogeny, metamorphism occurred deep underground, forming slate and gneiss. In the Tertiary period these mountain remnants came under heavy pressure as a result of plate tectonic processes during which the Alps were formed and the North American and Eurasian plates were separated.

Komáří vížka which lies on the Czech side, east of Zinnwald-Georgenfeld, right on the edge of the fault block. Consequently, it is a fault-block mountain range which, today has been incised by a whole range of river valleys whose rivers drain southwards into the Eger and northwards into the Mulde or directly into the Elbe. View from Mückentürmchen in the Eastern Ore Mountains to the west. The Ore Mountains are geologically considered to be one of the most heavily researched mountain ranges in the world. The main geologic feature in the Ore Mountains is the Late Paleozoic Eibenstock granite pluton, which is exposed for 25 miles along its northwest-southeast axis and up to 15 miles in width.
To the north of the Ore Mountains, west of Chemnitz and around Zwickau lies the Ore Mountain Basin which is only really known geologically. Here there are deposits of stone coal where mining has already been abandoned. The Ore Mountains are oriented in a southwest-northeast direction and are about 150 km long and, on average, about 40 km wide. To the east it is adjoined by the Elbe Sandstone Mountains and, to the west, by the Elster Mountains and other Saxon parts of the Vogtland. According to cultural tradition, Zwickau is seen historically as part of the Ore Mountains, Chemnitz is seen historically as just lying outside them, but Freiberg is included. The supposed limit of the Ore Mountains continues southwest of Dresden towards the Elbe Sandstone Mountains.
1,244 metres, in the Bohemian part of the range. The highest elevation on the Saxon side is the 1,215-metre-high Fichtelberg, which was the highest mountain in East Germany. Most of them occur around the Klínovec and the Fichtelberg. About a third of them are located on the Saxon side of the border. Even after the reclassification of natural regions by the Federal Agency for Nature Conservation in 1994 the Ore Mountains, region D16, remained a major unit group with almost unchanged boundaries. The climate of the higher regions of the Ore Mountains is characterised as distinctly harsh.
Temperatures are considerably lower all year round than in the lowlands, and the summer is noticeably shorter and cool days are frequent. 140 frost-free days per year are observed. Based on reports of earlier chroniclers, the climate of the upper Ore Mountains in past centuries must have been even harsher than it is today. Historic sources describe hard winters in which cattle froze to death in their stables, and occasionally houses and cellars were snowed in even after snowfalls in April. The population was regularly cut off from the outside world. The fault block mountain range that climbs from northwest to southeast, and which enables prolonged rain to fall as orographic rain when weather systems drive in from the west and northwest, gives rise to twice as much precipitation as in the lowlands which exceeds 1,100 mm on the upper reaches of the mountains.
