A model for the horst and graben structure of Midocean ridge crests based upon spreading velocity and basalt delivery to the Oceanic crust

Geofísica Internacional, 1974
La cresta de la dorsal del Pacifico oriental entre los 17° N a los 40° S se caracteriza por un horst central. Este rasgo se atribuye a! producto estacionario de una deriva constante en torno a la cresta, en que la varianza de la velocidad de inyección es

Surface Displacements Mechanism of the Dobi Graben from ASAR Time-Series Analysis of InSAR: Implications for the Tectonic Setting in the Central Afar Depression, Ethiopia

Remote Sensing, 2022
The Dobi graben is a Quaternary, NW-trending continental rift found within the East-Central Block (ECB) of the Afar Depression (AD) in Ethiopia. The AD might be the only place where three active rifts meet on land.

Relevant aspects to the recognition of extensional environments in the field

Boletín Geológico, 2021
The understanding of each geological-structural aspect in the field is fundamental to be able to reconstruct the geological history of a region and to give a geological meaning to the data acquired in the outcrop.

Dating of active normal fault scarps in the Büyük Menderes Graben (western Anatolia) and its implications for seismic history

Quaternary Science Reviews, 2019
Fault scarps, if well-preserved, include precise evidence of past earthquakes. Using cosmogenic 36Cl dating, the timing and slip of paleoearthquakes are recoverable beyond the available earthquake archives.

NEOGENE AND QUATERNARY SEDIMENTATION PATTERNS IN THE NORTHWESTERN HYBLEAN PLATEAU (SE SICILY): THE EFFECTS OF A COLLISIONAL PROCESS ON A FORELAND MARGIN

Rivista Italiana di Paleontologia e Stratigrafia, 2017
Miocene carbonates and marls in the northwestern margin of the Hyblean Plateau (SE Sicily) exhibit considerable thickness variations consistent with synsedimentary tectonism. In the Early-Middle Mio­cene carbonates (Ragusa Formation) a series of parallel
