Mesozoic mafic magmatism in North China: Implications for thinning and destruction of cratonic lithosphere
Y Zheng, Z Xu, Z Zhao, L Dai - Science China Earth Sciences, 2018 - Springer
Abstract The North China Craton (NCC) has been thinned from> 200 km to< 100 km in its
eastern part. The ancient subcontinental lithospheric mantle (SCLM) has been replaced by …

Widening of the Andes: An interplay between subduction dynamics and crustal wedge tectonics
Shortening of the continental lithosphere is generally accommodated by the growth of
crustal wedges building above megathrusts in the mantle lithosphere. We show that the …

Southward propagation of Nazca subduction along the Andes
The Andean margin is the plate-tectonic paradigm for long-lived, continuous subduction, yet
its geology since the late Mesozoic era (the past 100 million years or so) has been far from …

Initiation of the Andean orogeny by lower mantle subduction
Abstract The Cordillera of the Andes is a double-vergent orogenic belt built up by thickening
of South American plate crust. Several models provide plausible explanations for the …

The role of ridges in the formation and longevity of flat slabs
Flat-slab subduction occurs when the descending plate becomes horizontal at some depth
before resuming its descent into the mantle. It is often proposed as a mechanism for the …

Causes and consequences of flat-slab subduction in southern Peru
Flat or near-horizontal subduction of oceanic lithosphere has been an important tectonic
process both currently and in the geologic past. Subduction of the aseismic Nazca Ridge …

South-American plate advance and forced Andean trench retreat as drivers for transient flat subduction episodes
G Schepers, DJJ Van Hinsbergen, W Spakman… - Nature …, 2017 - nature.com
At two trench segments below the Andes, the Nazca Plate is subducting sub-horizontally
over∼ 200–300 km, thought to result from a combination of buoyant oceanic-plateau …

Overlapping slabs: Untangling subduction in NW South America through finite-frequency teleseismic tomography
Abstract Both the Caribbean and Nazca plates subduct beneath northwestern South
America. The configuration of the two subducted slabs and the nature of any interaction …

Detailed Structure of the Subducted Nazca Slab into the Lower Mantle Derived From Continent‐Scale Teleseismic P Wave Tomography
Abstract Nazca subduction beneath South America is one of our best modern examples of
long‐lived ocean‐continent subduction on the planet, serving as a foundation for our …

Abnormal seismological and magmatic processes controlled by the tearing South American flat slabs
The influence of flat slab subduction on the formation of intra-slab earthquakes, volcanic
activities and mantle seismic velocity anomalies remains unclear. We attempt to better …
