The area of Krousonas is located along the major fault zone of Krousonas-Tylissos, where large normal faults submerged the region of the Heraklion basin and uplifted Mount Psiloritis several million years ago.
Along the rural road from Krousonas towards the gorge of Agia Irini, the smoothed surface (fault mirror) of one of these faults appears, on which the tectonic slip lines are impressively visible.
