A closer look at the geometry of the Pampean flat slab’s southern termination

open access: yesFrontiers in Earth Science
We use a newly retrieved seismicity catalog that contains >115,000 double-difference relocated events in the vicinity of the southern termination of the Pampean flat slab in Central Chile and NW Argentina to infer the slab configuration at the ...

Eocene Volcanic Complex from Central British Columbia: The Role of Fractional Crystallization during the Magmatic Evolution

open access: yesLithosphere, 2022
The Challis-Kamloops belt of south-central British Columbia is a regionally extensive (>65,000 km2) magmatic province that erupted within the North American Cordillera during the Eocene (55-45 Ma).

Thermomechanical modelling of lithospheric slab tearing and its topographic response

open access: yesFrontiers in Earth Science, 2023
Lithospheric slab tearing, the process by which a subducted lithospheric plate is torn apart and sinks into the Earth’s mantle, has been proposed as a cause for surface vertical motions in excess of 100 s of meters. However, little is known about the mechanisms that help initiate and control the propagation of slab tearing and the associated uplift ...

A trapdoor mechanism for slab tearing and melt generation in the northern Andes [PDF]

open access: yesGeology, 2018
Segments of flat subduction are recognized in subduction zones, but little is known about the behavior of slabs along the edges of flat slab segments. Well-constrained earthquake data from the northern edge of the Peru flat slab segment reveal that the subducting Nazca slab is more contorted than previously assumed, with a prominent tear developed ...

Tomographic Imaging of Slab Segmentation and Deformation in the Greater Antilles

open access: yesGeochemistry, Geophysics, Geosystems, 2018
We present a new tomographic P wave model of the upper mantle in the east Caribbean region. The model was built using 3‐D finite frequency sensitivity kernels and ~20,000 teleseismic P and PP traveltime residuals from 535 events recorded across 130 ...

Seismic Evidence for Crustal Modification Across the Tanlu Fault Zone in Eastern China

open access: yesGeophysical Research Letters, 2022
The continental collision and subduction between the North China Craton and Yangtze Plate resulted in complex multistage tectonic episodes of the Tanlu fault zone.

An Integrated Multiscale Method for the Characterisation of Active Faults in Offshore Areas. The Case of Sant’Eufemia Gulf (Offshore Calabria, Italy)

open access: yesFrontiers in Earth Science, 2021
Diagnostic morphological features (e.g., rectilinear seafloor scarps) and lateral offsets of the Upper Quaternary deposits are used to infer active faults in offshore areas.

Gaps, tears and seismic anisotropy around the subducting slabs of the Antilles [PDF]

open access: yesTectonophysics, 2017
Seismic anisotropy in and beneath the subducting slabs of the Antilles is investigated using observations of shear-wave splitting. We use a combination of teleseismic and local events recorded at three-component broadband seismic stations on every major island in the area to map anisotropy in the crust, the mantle wedge and the slab/sub-slab mantle.
