Karelides

From Wikipedia, the free encyclopedia

Karelides is the ancient mountain chain, which located between Eastern Finland and Lapland. It formed current hill zone of Eastern Finland and Lapland's Arctic hills splitting the Centre Finland. Karelidit formed about 2000 million years ago, when thick sandstone sediments rocked and then folded when continental plates smashed. This made a ridge made of quartzite, which has stood there not caring of ice ages consume and weathering. Mountains in the very north-west Finnish Lapland belong to the newer Scandinavian Mountains, and because of that they are higher than other Finnish mountains. The third mountain group is Svecofennides, which stood there from Southern Finland to Sweden.
