Abstract

Assessmemt of hydrocarbon potential of uplift structures in sedimentary basins from their geological history (Ateshgah structure in Baku Archipelago)

Highlights

  • Ateshgah uplift is located in the open sea, in the central part of the Baku archipelago shelf, 30 km to the south-south-east of Bandovan uplift, in the river Kura outfall, within the continental slope of the Caspian Sea eastern shelf [Aliyev et al, 1985] (Fig. 1)

  • Since majority of mud volcanoes at either crestal or pericrestal parts of local uplifts were active in the recent geological past or are still active, their eruption products formed volcanic cones over corresponding uplifts [Aliyev, 2006; Aliyev et al, 2015]

  • Ateshgah uplift is a syndepositional fold complicated with faults appearing during each time interval of its development

Summary

Introduction

Ateshgah uplift is located in the open sea, in the central part of the Baku archipelago shelf, 30 km to the south-south-east of Bandovan uplift, in the river Kura outfall, within the continental slope of the Caspian Sea eastern shelf [Aliyev et al, 1985] (Fig. 1). The Ateshgah sandbank structure is similar, by its form and size, to the folds developed in the Kura depression and Baku archipelago and is of the short brachiform type. Correspondence of those cones to positive structures, i. BABAYEV them gives grounds for a statement that the basin floor within the Baku archipelago is, in general, conforming This instance could play a positive role in prospecting and exploration of local uplifts. The amplitude of the three faults that transversely cross the eastern limb of the structure reaches 900 m in the south-western limb and 100 m in the north-eastern one.
