Inner Eastern Carpathians

The Inner Eastern Carpathians are a geological region within the larger Carpathian Mountains system in Europe. This mountain range is characterized by distinct structural blocks, including the East Carpathian Block and the South Carpathian Block. These blocks are composed of ancient crystalline and metamorphic cores, overlaid with younger sedimentary rocks, primarily limestones and dolomites from the Mesozoic Era.1

Volcanic rocks, formed less than 50 million years ago, also contribute to the Inner Eastern Carpathians' geology, running in a northwest-to-southeast line. This mountain range is less densely populated than the Western Carpathians, with settlements concentrated in the valleys. The primary ethnic groups in this region are Romanians and Hungarians, with Ukrainian populations in the northern parts.12
