In all cases we have followed the 1:100 000 maps rather the 1:250 000 map. Artinskian Yakhtashian Cisuralian (1) The geological map of Nazwa (1:250 000; Béchennec et al. 1992b) depicts the Hawasina unit immediately E of Nizwa as Umar Group, while the geological map of Sakmarian Sakmarian Birkat Al-Mawz (1:100 000; Hutin et al. 1986) depicts the same area as Al-Aridh Group. Asselian Asselian (2) Hawasina rocks west of Rustaq are differently mapped 298.9 Ma in the 1:250 000 and 1:100 000 map scale (Béchennec et al. 1992a; Beurrier et al. 1986, respectively). In the Fig. A.3. Comparison of the Permian Period between the ‘International 1:250 000 map some rocks are presented as Matabat Stratigraphic Chart’ and ‘Tethyan Time Scale’. Modified from Angiolini Fm. (Hamrat Duru Group) while the same area in the et al. (2016). 1:100 000 map is Umar Group.
