Ancient planation surfaces are represented in different ways within mountain and foothill zones of the Ukrainian Carpathians. Poloninskaya, Beskidskaya and Prirechnaya (upper and lower) surfaces are spread in mountains, Krasnenskaya and Loevskaya surfaces - in eastern foothills (Predcarpatye), Skrideyskaya, Boronyavskaya and Veliko-Kopanskaya surfaces-in western foothills (Zacarpatye). The Upper Prirechnaya surface of the Central Carpathians corresponds to Krasnenskaya and Skrideyskaya ones at the foothills, and Lower Prirechnaya corresponds to Loevskaya, Boronyavskaya and Veliko-Kopanskaya ones.

Planation surfaces were formed due to lessening of the tectonic uplifts rate at the end of early erogenous and in middle erogenous stages as well as at the beginning of the late erogenous stage of the Ukrainian Carpathians evolution, which are Late Helvetian (Poloninskaya surface), Pannonian (Beskidskaya), Late Pliocene (Upper Prirechnaya, Krasnenskaya and Skrideyskaya) and Early Anthropogene (Lower Prirechnaya, Loevskaya, Boronyavskaya and Veliko-Kopanskaya ones) correspondingly.
