The Sava Zone (named after the river Sava) is an oceanic suture that strikes roughly NNW to SSE through Serbia and is mostly covered in the north by the sediments of the Pannonian Basin. Outcrops can be found in the Fruška Gora (Fruška mountains). Here the unit is composed of blueschists and ophiolites. In the south outcrops of the Sava Zone occur in the Balkan and Rhodope Mountains. This includes the Senonian Flysch and the rocks cropping out in the Jastrebac Window.
