“…the region has a wide range of crustal (∼30-50 km,Delph, Biryol, et al, 2015;Karabulut et al, 2019;Zor, 2008) and lithospheric depths (∼52-146 km, e.g.,McKenzie, 2020;McKenzie & Priestley, 2008;Motavalli-Anbaran et al, 2016;Priestley et al, 2012;Priestley & McKenzie, 2013;Skobeltsyn et al, 2014), we simplify the physical model with average values for the crust and lithosphere (40 and 80 km, respectively) to avoid isostatic effects that might be caused by lateral variations of the compositional fields (e.g.,Shaw & Pysklywec, 2007). The reference density contrast (ρ 0 , Model-1, Table1) between the lithosphere and underlying sublithospheric (asthenospheric) mantle is set to 1.2% (e.g.,Faccenna et al, 2014. Due to the uncertainties of densities arising from changing compositional aspects of the materials (i.e., crust, lithosphere, and mantle), we also test different density parameters (i.e., Model-3 for ρ 1 and Model-4 for ρ 2 ,Faccenna et al, 2014; Karabulut et al, 2019, respectively) and wet olivine rheology beneath the crust…”
