Deciphering the Late Paleozoic–Cenozoic Tectonic History of the Inner Central Andes Forearc: An Update From the Salar de Punta Negra Basin of Northern Chile

open access: yesFrontiers in Earth Science, 2022
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic–Cenozoic tectonic evolution of the inner Andean forearc of northern ...

Constraints on fault and lithosphere rheology from the coseismic slip and postseismic afterslip of the 2006 M_w 7.0 Mozambique earthquake [PDF]

open access: yes, 2012
The 2006 M_w 7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane (~75°). The amount of slip in the earthquake decreased from depths of ~10 km toward the surface, and this shallow slip deficit was at least

Inversion tectonics of the benue trough

open access: yesGlobal 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.

Seismological structure of the 1.8 Ga Trans-Hudson Orogen of North America [PDF]

open access: yes, 2016
Precambrian tectonic processes are debated: what was the nature and scale of orogenic events on the younger, hotter, and more ductile Earth? Northern Hudson Bay records the Paleoproterozoic collision between the Western Churchill and Superior plates—the ∼

The Hudson Bay Lithospheric Experiment (HuBLE) : Insights into Precambrian Plate Tectonics and the Development of Mantle Keels [PDF]

open access: yes, 2015
The UK component of HuBLE was supported by Natural Environment Research Council (NERC) grant NE/F007337/1, with financial and logistical support from the Geological Survey of Canada, Canada–Nunavut Geoscience Office, SEIS-UK (the seismic node of NERC ...

Active Inversion Tectonics from Algiers to Sicily [PDF]

open access: yes, 2019
Using an updated active faults map in the easternmost Western Mediterranean (Algeria to Calabria), plus constraints from geodesy (GPS horizontal motion) and seismology (focal mechanisms) input in a strain model, we discussed how the slow Africa-Eurasia motion (4 mm/year) is accommodated along this segment of the Mediterranean. The width of the inverted

Interpretation of the tectonic evolution of the western part of the Sava Depression: structural analysis of seismic attributes and subsurface structural modeling

open access: yesJournal of Maps, 2019
This paper presents the results of an extensive structural investigation of the western part of the Sava Depression (SW part of the Pannonian Basin System) and provides insights in the tectonic evolution of the investigated area. Structural analyses were

A review on the analysis of aeromagnetic anomaly and its geological and tectonic applications

open access: yes地球与行星物理论评, 2022
Aeromagnetic anomaly has the obvious advantages of wide coverage, low cost and high lateral resolution in geological structure research, and has been widely used in concealed magmatic rock and faults detection, tectonic characteristics (e.g.

Geo-structural map of the Laguna Blanca basin (Southern Central Andes, Catamarca, Argentina) [PDF]

open access: yes, 2015
The Laguna Blanca basin is a rhomb-shaped basin located at the SE margin of the Puna plateau in the southern Central Andes (Catamarca, Argentina). An interactive analysis using remote sensing and field mapping enabled us to produce a geo-structural map ...

Stretching and Contraction of Extensional Basins With Pre-Rift Salt: A Numerical Modeling Approach

open access: yesFrontiers in Earth Science, 2021
We present a series of 2D thermo-mechanical numerical experiments of thick-skinned crustal extension including a pre-rift salt horizon and subsequent thin-, thick-skinned, or mixed styles of convergence accompanied by surface processes.
