TLDR
Zhang et al. as mentioned in this paper performed ion microprobe (SHRIMP) dating on zircons of a metagabbrobot and four eclogites from the high pressure/ultra high pressure (HP/UHP) metamorphic terrane of western Dabieshan (also known as the Hong'an Block), China.About:

Tectonic evolution of a composite collision orogen: An overview on the Qinling–Tongbai–Hong'an–Dabie–Sulu orogenic belt in central China
Yuan-Bao Wu,Yong-Fei Zheng +1 more
TL;DR: In this article, the authors present an overview of regional geology, geochronology and geochemistry for the composite orogenic belt of the Qinling-Tongbai-Hong'an orogens.

Early Cretaceous adakitic granites in the Northern Dabie Complex, central China: Implications for partial melting and delamination of thickened lower crust
Qiang Wang,Derek A. Wyman,Ji-Feng Xu,Ping Jian,Zhen-Hua Zhao,Chaofeng Li,Wei Xu,Jinlong Ma,Bin He +8 more
TL;DR: In this paper, the authors presented Early Cretaceous (143-129 Ma, new Sensitive high-resolution ion microprobe (SHRIMP) zircon U-Pb ages) adakitic granites, which are directly associated with a contemporary metamorphic core complex.

Closure of the Proto-Tethys Ocean and Early Paleozoic amalgamation of microcontinental blocks in East Asia
Sanzhong Li,Shujuan Zhao,Xin Liu,Huahua Cao,Shan Yu,Xiyao Li,Ian D. Somerville,Shengyao Yu,Yanhui Suo +8 more
TL;DR: In this paper, the Proto-Tethys Ocean is defined as a complex complex paleo-ocean located between the Tarim-North China and the Sibumasu/Baoshan blocks, and it was opened from the rifting of the Supercontinent Rodinia and mainly closed at the end of the Early Paleozoic.
Journal ArticleDOI
Ultrahigh-pressure minerals and metamorphic terranes – The view from China
TL;DR: For example, the very rare occurrence of microdiamond inclusions in zircons from Dabie-Sulu UHP rocks may reflect high f O 2 attending recrystallization inasmuch as epidote is rather common as mentioned in this paper.
Journal ArticleDOI
The Dabie–Sulu continental collision zone: A comprehensive review
TL;DR: The Dabie-Sulu Triassic orogen in central-eastern China was created by northward subduction of the Yangtze cratonal plate beneath the Sino-Korean craton.

TEMORA 1: a new zircon standard for Phanerozoic U–Pb geochronology
Lance P. Black,Sandra L. Kamo,Charlotte M. Allen,John N. Aleinikoff,Donald W. Davis,R. J. Korsch,Chris Foudoulis +6 more
TL;DR: The TEMORA 1 zircon standard derives from the Middledale Gabbroic Diorite, a high-level mafic stock within the Palaeozoic Lachlan Orogen of eastern Australia as mentioned in this paper.
Journal ArticleDOI
Zircon U-Pb ages for the Early Cambrian time-scale
TL;DR: In this paper, single zircons from two Early Cambrian volcanic horizons have been analyzed using the SHRIMP ion microprobe, revealing the presence of both detrital or xenocrystic grains as well as areas within grains that have lost radiogenic Pb.

Ore lead isotope ratios in a continuously changing earth
G.L. Cumming,J.R. Richards +1 more
TL;DR: In this paper, a critical re-assessment of the construction of simple ore lead isotopic development curves is followed by three fresh approximations, all designed to involve the minimum possible number of assumptions.

Geochronology of Neoproterozoic syn-rift magmatism in the Yangtze Craton, South China and correlations with other continents: evidence for a mantle superplume that broke up Rodinia
TL;DR: In this article, the authors showed that there were two major phases of widespread bimodal magmatism in South China during the Neoproterozoic, one starting before the continental rift but continued into the first two stages of the rifting.

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).
