Svecokarelian orogeny is the name of an alternative and slightly different orogeny conceptualization that overlaps with the Svecofennian orogeny. As of 2004 there was no consensus on the usage of the terms. Some geologists prefer the term Svecofennian orogeny rather than Svecokarelian orogeny because

The Svecofennian orogeny developed as a succession of four orogenies which by chronological order are: the Lapland-Savo orogeny, the Fennian orogeny, the Svecobaltic orogeny and the Nordic orogeny. In broad terms, regardless of details, it has been proposed that the Svecofennian orogeny involved

Prior to the Svecobaltic orogeny proper there was period of northward-directed subduction at what is now south-central Sweden and southern Finland. The subduction lasted from 1860 to 1840 million years ago and was accompanied by

The stage to the Fennian orogeny was set by a collision between Keitele and Karelia about 1920–1910 million years ago which resulted in a reorganization of the local
