Deformational sequence of inversion in the Paramirim Aulacogen, northern region of the intracontinental sector of the Araçuaí Orogen [PDF]

Brazilian Journal of Geology, 2023
The Paramirim Aulacogen was filled by the Espinhaço and São Francisco supergroups in the period from 1.75 to 0.69 Ga, and suffered partial inversion during the Ediacaran.

Geophysical response characteristics and genetic analysis of tectonic coal:take Zhaozhuang coal mine in Jincheng mining area as an example

矿业科学学报, 2018
The distribution of tectonic coal is of great importance to the exploration and development of coal-bed methane and the safety production of coal mine.The Zhaozhuang coal mine in Jincheng mining area is took as example.Firstly, the vertical distribution ...

Inversion tectonics of the benue trough

Global Journal of Geological Sciences, 2006
The Benue Trough, an aulacogen at the entrant of the Gulf of Guinea in Nigeria, has been historically studied from the concepts of ortho-mio-eu-geosynclines at outcrops and in the subsurface. Its structural evolution reveals a tectonic scenario compatible with Plate tectonic evolution of the Atlantic Ocean.

Seismic Exploration of the Deep Structure and Seismogenic Faults in the Ligurian Sea by Joint Multi Channel and Ocean Bottom Seismic Acquisitions: Preliminary Results of the SEFASILS Cruise

Geosciences, 2020
The north Ligurian margin is a complex geological area in many ways. It has witnessed several phases of highly contrasting deformation styles, at both crustal scale and that of shallower cover tectonics, simultaneously or in quick succession, and with ...

Crustal Thickness Variations and Tectonic Settings in the Southwest Cameroon Inferred from Gravity and Topography Data

Lithosphere, 2022
EIGEN 6C4 gravity anomalies are interpreted to determine the lateral and vertical variations in the crust and upper mantle structure and their influence on the isostasy of the coastal plain, transition zone between the Congo Craton (CC), the Pan-African ...

Seismological and Gravity Data Integration to Derive Regional Fault and Subduction Systems in Myanmar [PDF]

E3S Web of Conferences
Tectonic activity in Myanmar is influenced by the convergence of the Indian Plate and the Burma Plate, which form an active subduction zone in western Myanmar (Rakhine) and the Sagaing Fault system in eastern Myanmar.

Inversion tectonics: a brief petroleum industry perspective [PDF]

Solid Earth, 2020
Abstract. Inverted structures provide traps for petroleum exploration, typically four-way structural closures. As to the degree of inversion, based on a large number of worldwide examples seen in various basins, the most preferred petroleum exploration targets are mild to moderate inversion structures, defined by the location of the null points.

Tectonic discrimination diagrams revisited [PDF]

, 2006
The decision boundaries of most tectonic discrimination diagrams are drawn by eye. Discriminant analysis is a statistically more rigorous way to determine the tectonic affinity of oceanic basalts based on their bulk-rock chemistry.

Positive tectonic inversion of the Western Sicily margin: Geodynamic implications for the central sector of the Africa-Eurasia plate boundary

BSGF - Earth Sciences Bulletin
The offshore western Sicily region is located at the active Africa-Eurasia plate boundary, between the southern Tyrrhenian backarc basin and the African continental margin, where tectonic processes make this sector prone to strong earthquakes and ...

Constraints on the thermal and tectonic evolution of Greymouth coalfield [PDF]

, 1999
The southern end of the Paparoa Range in Westland, South Island, New Zealand, comprises an asymmetrical, southward plunging, faulted (Brunner-Mt Davy) anticline, the eastern limb of which is common with the western limb of an asymmetrical (Grey Valley ...
