These layers reflect alternations of marine, brackish, lacustrine, and terrestrial environments of deposition. The oldest known rock in the Baltic Shield is gneiss in southeastern Karelia, which gives U-Pb zircon ages.5.

The geological time scale and the techniques used to define it are not circular. The basement rocks comprise a mixture of pre-Variscan basement, Late-Variscan granitoids associated with clastic and volcaniclastic rocks, and post-Variscan volcaniclastic rocks.
