title: Mesozoic source rock systems at the junction between Eurasia and Gondwana: Tethyan vs Boreal controls in the Southeastern Caucasus, Northeastern Azerbaijan 
abstract: Northeastern Azerbaijan occupies a complex geodynamic setting at the convergence of the Scythian-Turanian (Epihercynian) Platform and the Meso-Tethyan accretionary prism, evolving along the Northern Gondwana margin. Functioning as a key segment of the regional North Crimea – Greater Caucasus – Kopetdagh Meso-Tethys marginal sea, the accretionary prism records a pivotal transition from Lower-Middle Jurassic shale-rich aspid facies to Cretaceous flysch sequences. Despite decades of research on Mes
