Entity: Siberian craton margins
Triple: [Baikal orogeny, affects, Siberian craton margins]

The Siberian craton margins are the ancient, stable outer zones of the Siberian continental core that were tectonically deformed and reworked during major mountain-building events such as the Baikal orogeny.
