摘　　要：The numerical results of thermal modeling studies indicate that the lithosphere is cold and strong beneath the Black Sea basin.The thermal lithospheric thickness increases southward from the eastern Pontides orogenic belt(49.4 km) to Black Sea basin(152.2 km).The Moho temperature increases from 367℃in the trench to 978℃in the arc region.The heat flow values for the Moho surface change between 16.4 mW m^(-2) in the Black Sea basin and 56.9 mW m^(-2) in the eastern Pontides orogenic belt. Along the southern Black Sea coast,the trench region has a relatively low geothermal potential with respect to the arc and back-arc region.The numerical studies support the existence of southward subduction beneath the Pontides during the late Mesozoic-Cenozoic. 关键词：大洋岩石圈海盆地造山带俯冲特提斯热结构莫霍面温度极性
