Active impact of industrial activity on rocks creates huge masses of artificial formations, diverse in composition and properties. Attempts to classify the types of technogenic rocks are known in the literature. According to the studies of Moscow University, technogenic formations are subdivided into technogenic-altered, technogenic-redeposited and technogenic-formed.

The Kola Peninsula and the Karelian ASSR in the engineering-geological plan represent the territory of near-surface bedding of rocky and semi-rocky rocks of the crystalline basement of the Baltic Shield, overlain by thin glacial, late- and post-glacial sediments of Quaternary age.
