Permo-Triassic Collision, Subduction-Zone Metamorphism, and Tectonic Exhumation Along the East Asian Continental Margin
TLDR
The Tongbai-Dabie-Sulu (east-central China)-Imjingang-Gyeonggi (central Korea)-Renge-Suo (Southwestern Japan)-Sikhote-Alin orogen along the paleo-Pacific edge of cratonal Asia.Abstract:
Convergent plate motion at ∼320–210 Ma generated the Tongbai-Dabie-Sulu (east-central China)-Imjingang-Gyeonggi (central Korea)-Renge-Suo (Southwestern Japan)-Sikhote-Alin orogen along the paleo-Pacific edge of cratonal Asia. This amalgamated belt reflects collision between the Sino-Korean and Yangtze cratons on the SW portion, and accretion of outboard oceanic arcs ± sialic fragments against the NE margin. Subducted Proterozoic-Paleozoic continental and oceanic crustal complexes underwent high- and ultrahigh-pressure metamorphism at low to moderate temperatures. Tectonic slices of sialic crust episodically disengaged from the downgoing plate and, driven by buoyancy, ascended rapidly to midcrustal levels from depths exceeding 90–200 km after continental collision in east-central China plus or minus Korea, and from ∼30–50 km after arrival of far-traveled oceanic terranes in SW Japan and the Russian Far East. On achieving neutral buoyancy and stalling out at 10–20 km depth, later doming, gravitation...read more

Phanerozoic tectonics of the South China Block: Key observations and controversies
TL;DR: In this article, the authors presented an overview of key geological observations in the South China Block with respect to its Phanerozoic tectonics, and proposed a geodynamic model for the Mesozoic evolution of the SCB, which is characterized by strong thrusting/transpression, anatexic granitic magmatism, high-grade metamorphism and the poor involvement of the juvenile mantle derived rocks.

Metamorphic chemical geodynamics in continental subduction zones
TL;DR: In this paper, a review of the geochemical properties of UHP terranes is presented, focusing on the following issues in continental subduction zones: the time and duration of uHP metamorphism, the origin and action of metamorphic fluid/melt inside UHP slices, the element and isotope mobilities under HP to UHP conditions during continental collision, the origins of premetamorphic protoliths and its bearing on continental collision types, and the crustal detachment and crust mantle interaction in subduction channels.

Tectonics and Climate of the Southern Central Andes
Manfred R. Strecker,Ricardo N. Alonso,Bodo Bookhagen,Barbara Carrapa,George E. Hilley,Edward R. Sobel,Martin H. Trauth +6 more
TL;DR: The history of the southern central Andes, including the world's second largest plateau and adjacent intermontane basins and ranges of the Eastern Cordillera and the northern Sierras Pampeanas of Argentina and Bolivia, impressively documents the effects of tectonics and topography on atmospheric circulation patterns, the development of orographic barriers, and their influence on erosion and landscape evolution at various timescales as discussed by the authors.

Dynamics of orogenic wedges and the uplift of high-pressure metamorphic rocks
TL;DR: In this paper, the authors model a sink-shaped continua with a rigid buttress behind and a subducting litho-spheric slab beneath, where the gravity forces generated by the wedge geometry balance the traction exerted on its underside by the sink.

Collision of the North China and Yangtse Blocks and formation of coesite-bearing eclogites: Timing and processes☆

TL;DR: In this article, the uplift history of eclogite in the Dabie Mountains can be subdivided into two stages: (1) fast uplift driven by thrust during continental-continental collision and deep subduction (at 221 Ma) of the continental crust; (2) later gentle uplift with rise of the Dabbie Mountains in the late Jurassic and Cretaceous (at 134 Ma).

TL;DR: In this article, the authors proposed a boundary geometry model for the collision of the North China Block and the South China Block (SCB) that predicts the distribution and ages of metamorphism along the suture and the observed local but intense Triassic deformation.
