Geological map of the study area simplified from the geological maps of Ravar and Zarand in the scale of 1:100.000 (Geological Survey of Iran 1995a, b). Locations of measured stratigraphic sections are shown. The boundary between the Ab-Haji and Nayband formations in the Ravar geological map is based on our fieldwork and the subdivision of the hitherto undifferentiated “Shemshak Formation”
