From Micro- to Satellite Gravity: Understanding the Earth

“…Quantitative examination of magnetic curve Z enabled to delineate two magnetic objects. The main target speciously is a source of the Talysh-Vandam gravity anomaly (TVGA) (its upper surface agrees with the data obtained from SD-1 drilling) [64]. The obtained data were utilized at the stage of construction of PhysicalGeological Model (PGM) of a first approximation [16].…”

“…A combination of latitudinal and longitudinal faults strongly complicates the deposit structure. The Katekh deposit was investigated by mining and drilling up to a depth of 500 m. The main ore minerals of the Katekh deposit are pyrite, sphalerite, chalcopyrite and galena [64].…”

“…For Azerbaijan territory is generally typical frequently changing of rocks both on vertical and lateral, presence of multifarious fold and fault structures of different orders, regional and local metamorphism [64]. All these factors complicate development of the reliable physical-geological models of the region under study.…”

Evolution Model for the Absheron Mud Volcano: From Stratified Sediments to Fluid Mud Generation

“…Phase 1: At 3.4 My, end of the rapid deposition of the PS (over 3.5 km in 2 My) above the gas-mature Maykop Formation that generated hydrocarbons diffusing slowly through the sedimentary column (Figure 11a). The Maykop Formation started generating gas during the Late Miocene in the Shah Deniz region located in a structural setting comparable to Absheron (Figure 2.9 in Alizadeh et al, 2017). Moreover, the deposition of the ASF provided an efficient seal allowing a slow and uniform overpressure build-up in the PS generated by high sedimentation rates.…”

“…It is also a province of intense O&G (oil and gas) activity. This is favored by the presence of a mature Oligocene-Miocene source rock (Maykop Formation), numerous regional reservoirs deposited during the Pliocene (e.g., Nadkirmakinskaya Glinistaya, Balakhany, Fasila, Sabunchi and Surakhany Formations), structural traps in anticline crests and a good seal interval composed by the entire Quaternary section (Alizadeh et al, 2017;Guliyev et al, 2011;Javanshir et al, 2015). The SCB also holds the densest distribution of MVs worldwide (Dimitrov, 2002;Kopf, 2002;Milkov, 2000).…”
