Evolution of volcanism in graben and horst structures along the Cenozoic Cameroon Line (Africa): implications for tectonic evolution and mantle source composition [PDF]

open access: yesMineralogy and Petrology, 2008
Tombel graben and Mounts Bambouto are two volcanic fields of the typical system of alternating graben and horst structure of the Cameroon Volcanic Line. Tombel graben is a young volcanic field, whereas Mounts Bambouto horst is an old stratovolcano with calderas.

The Araripe Basin in NE Brazil: An intracontinental graben inverted to a high-standing horst

Tectonophysics, 2014
Abstract The Mesozoic sediments of the Araripe Basin peak at ca. 1000 m, more than 500 m above the host Precambrian basement. This means that an intracontinental graben has been inverted to a topographically high-standing horst, which raises four fundamental questions: (1) Where are the inversion structures? (2) What is the age of the inversion?

Spectral Ratio Estimates for Site Effects on the Horst–Graben System in West Turkey [PDF]

open access: yesPure and Applied Geophysics, 2013
Recordings of micro- and moderate-size local earthquakes have been used to quantify site effects in the central-west Turkey which contains one of the world’s best examples of a rapid intra-continental extension with its high population and industrial potential.

Redefining Horst and Graben Distribution in The Onshore Part of The North East Java Basin and Its New Exploration Opportunity

Proceedings of Indonesian Petroleum Association, 46th Annual Convention & Exhibition, 2022, 2022
The onshore part of North East Java Basin (NEJB) is a well-known hydrocarbon producing area in Indonesia, with the largest proven reservoir being the Oligo - Miocene carbonates which accumulated over basement horsts. Currently, the understanding of horst distribution is based on previous publications. However, new integration studies on surface data (e.

Geothermal anomalies in the Valles‐Penedes Graben Master Fault: Convection through the Horst as a possible mechanism

Journal of Geophysical Research, 1990
Four different mechanisms (frictional heating, magmatic intrusion, free convection, and forced convection) have been tested as possible causes to explain the localized and relatively high geothermal anomalies found along master faults of graben structures. Forced convection is the only mechanism found to be generally able to generate the anomalies. The

Gravity and magnetic survey of the Oaxaca city region: Cenozoic horst-and-graben structure superimposed on the Oaxaca–Juarez terrane boundary, southern Mexico

Journal of South American Earth Sciences, 2010
Abstract A geophysical survey of the Oaxaca Fault along the north-trending Etla and Zaachila valleys area, southern Mexico, shows a series of NNW–SSE Bouguer and magnetic anomalies with steeper gradients towards the east. The Oaxaca Fault represents Tertiary extensional reactivation of the Juarez shear zone that constitutes the boundary between the ...
