Algerian geologic formation made up of sedimentary rock From Wikipedia, the free encyclopedia
The Zaouïa Formation, also known as the Zaouïa Schists,[1] is a Middle Ordovician (Darriwilian) geologic formation in Algeria. The formation crops out in the Aïssa Mimoun Massif near Zaouïa of Stita at the confluence of Wadi Stita and Wadi Seba at about 5 kilometres (3.1 mi) northeast of Tizi-Ouzou in the municipality of Makouda,[2] in the Kabylian Mountains of northern Algeria. The type locality is about 29 kilometres (18 mi) away from the Katian outcrops of northern Djurdjura.[3]
