Abstract

Fault plane solutions1 and the offset of geomorphic and man-made features2–4 show that present-day displacements on the North Anatolian fault zone are right-lateral (Fig. 1). The present analysis of some of the mesoscopic faults and joints cutting Upper Neogene–Lower Pleistocene continental sediments in intermontane basins between Cerkes and Erbaa indicates that there was left-lateral motion on the fault zone during part of its neotectonic evolution. The structures include conjugate reverse faults striking north-west, conjugate normal faults and joints striking north-east, and conjugate vertical joints enclosing an acute angle about a north-east trending bisector (Figs 2 and 3).
