Structural evolution of horst and half-graben structures proximal to a transtensional fault system determined using 3D seismic data from the Shipwreck Trough, offshore Otway Basin, Australia

Marine and Petroleum Geology, 2018
Abstract Using a three-dimensional (3D) seismic reflection dataset from the Shipwreck Trough, offshore Otway Basin, southern Australia, we aim to characterise and understand the structural evolution of the Shipwreck Fault Zone (SFZ) and associated extensional structures.

The Nature and Origin of the Horst and Graben Structure of Southern Oregon

The Journal of Geology, 1929
In southern Oregon east of the Cascade Mountains a varied series of Tertiary lavas is cut by the northern continuation of the Basin Range faults, giving rise principally to relatively undissected horst and graben structure rather than to tilted fault-block mountains. The tensional origin of these faults is indicated by definite normal faulting, curving,

Implications of horsts and grabens on the development of canyons and seismicity on the west africa coast

Journal of African Earth Sciences, 2018
Abstract Subsurface basement topography in the Nigerian portion of the Benin Basin has been studied using borehole data of wells drilled to the basement and one strike line of seismic section. Two areas of a sharp drop in topography with a horst in between were observed in the study area.

Icelandic Tectonics—Graben or Horst ?

Geological Magazine, 1941
The younger rocks of Iceland (Pliocene to Present Day) occupy the broad median zone shown in Text-fig. I; the boundaries are only approximate in places, and information is lacking with regard to the eastern one particularly. Outside this zone early Tertiary basalts predominate but (I) the uppermost basalts are regarded by some authors as Quaternary, (2)

A Method of Graben and Horst Formation

The Journal of Geology, 1958
Grabens and horsts between transcurrent faults in New Zealand, currently explained by normal faulting, are shown to be caused by lateral displacement. The mechanics of the formation of such features is explained.

JABIRU FIELD — HORST, SUB- HORST OR INVERTED GRABEN?

The APEA Journal, 1989
With control from only the Jabiru 1A discovery well and a grid of seismic lines 3 km apart, original oil- in- place at Jabiru was estimated by the operator as 620 MMBBL (100 MkL). With a 3- D seismic grid and three more wells, the original oil- in- place estimate was reduced to 45 MMBBL (7 MkL).

High-altitude Plio–Quaternary fluvial deposits and their implication on the tilt of a horst, western Anatolia, Turkey [PDF]

Geomorphology, 2006
This study investigates the origin and regional tectonic implications of high-altitude Plio (?)-Quaternary fluvial deposits developed over the Bozdak horst which is an important structural element within the horst-graben system of western Anatolia ...
