Introduction
Zhicai Zhu is currently a postdoctoral researcher at the School of Earth Sciences, University of Bristol (UK) and the Institute of Geology, CAGS. His interests mainly include the sedimentary environmental changes across the terrestrial Permian-Triassic transition and the closure process of the Meso-Tethys ocean in central Tibet.

Article

The timing of collision between the Lhasa and Qiangtang blocks is crucial to understanding the plate tectonics of the Tibetan Plateau. Here we track block movements through a sedimentological study of the Lower Cretaceous nonmarine Duoni Formation, which widespreadly crops out in the central segment of the Bangong-Nujiang Suture Zone and unconforma...
Article
Ediacaran cap dolomites are strong evidence for the glaciation during the Neoproterozoic. Stratigraphic-sedimentological studies combined with δ¹³C and δ¹⁸O isotope analyses are used for defining the processes of post-glacier environmental changes and sea-level rise caused by glacier melting and the reconstruction of the depositional environments f...
Article
It has been suggested that boninites and associated volcanic rocks found in supra-subduction zone (SSZ) ophiolites form in a forearc setting, meaning that these rocks could provide crucial constraints on understanding the magmatic response to subduction initiation. Here, we report newly documented forearc basalts (FAB) and boninites from the Beila...
Article
The suggested Early Cretaceous timing of early formation of the Tibetan Plateau remains controversial. This study investigates this uncertainty by examining newly identified Early Cretaceous adakite-like magmatic rocks in the Rutog and Nyima areas of the northern–central Tibetan Plateau. Zircon UPb dating indicates that these rocks formed at ca. 11...
Article
The Early Paleozoic paleogeographic locations of the Tibetan terranes in Gondwana remain poorly constrained. This study reports petrology, zircon LA-ICP-MS U-Pb ages, whole-rock major and trace element compositions, and Sr-Nd-Hf isotopic data for the gneissic granites in the Amdo microcontinent, central Tibetan Plateau. LA-ICP-MS zircon U-Pb dating...

Accompanying Gondwana assembly, widespread but diachronous Ediacaran-early Paleozoic magmatism of uncertain origin occurred along the supercontinent's proto-Tethyan margin. We report new geochemi-cal, isotopic, and geochronological data for Cambrian magmatic rocks (ca. 500 Ma) from the Gondwana-derived North Lhasa terrane, located in the present-da...

The evolution of the Mozambique Ocean spans the Rodinia and Gondwana supercontinent cycles playing a key role in Earth history. Integrated petrological, geochronological, geochemical, and isotopic data on the Neoproterozoic units from the Lhasa terrane, Tibet, constrain the magmatic and metamorphic evolution of the ocean. Our results reveal two mag...
Article
Knowledge of the early Paleozoic tectonic framework of the northern margin of Gondwana continent is critical for reconstructions of the Gondwana supercontinent. Early Paleozoic leucogranite and gneissic granite units within the South Qiangtang Terrane, northern Tibetan Plateau, can constrain the timing and geological processes that occurred along t...
Article
Magmatic rocks preserve a lot of information about the formation and evolution of continental crust, and they play an important role in understanding the growth and reworking of ancient continent. Cretaceous magmatic rocks occurring in the Lhasa terrane are a window to investigate magmatic processes and continental evolution of the Tibetan Plateau....
Article
It is still hotly debated whether the subduction of the Indus-Yarlung Zangbo Tethyan oceanic lithosphere led to Cretaceous magmatism in the north Lhasa terrane or not. Here, we provide new data on adakitic dacite in the Rutog area, western Tibetan Plateau. Zircon U-Pb dating and Lu-Hf analyses yielded a weighted-mean ²⁰⁶Pb/²³⁸U age of ca. 97 Ma for...
Article
Full-text available
The Paleozoic tectonic framework and paleo–plate configuration of the northern margin of Gondwana remain controversial. The South Qiangtang terrane is located along the northern margin of Gondwana and records key processes in the formation and evolution of this supercontinent. Here, we present new field, petrological, zircon U–Pb geochronological,...

早白垩世多尼组沿西藏北部班公湖—怒江缝合带沿线广泛分布,其沉积环境、碎屑组成和沉积物源等记录了班公湖—怒江特提斯洋闭合后拉萨—羌塘地体碰撞的演化历史。班戈地区多尼组以角度不整合于侏罗纪海相复理石之上,主要由砾岩、砂岩、粉砂岩、泥岩及少量安山岩夹层组成。砂岩中普遍发育槽状、板状、楔状交错层理,泥岩中可见泥裂,砾岩多为透镜状并发育叠瓦状构造,指示其形成于河流—三角洲沉积,总体呈现出向上变粗的沉积组合序列。对多尼组中安山岩夹层样品进行LA-ICP-MS 锆石U-Pb定年,获得206U/238Pb 加权平均年龄为114 ± 0.4 Ma。对砾岩中砾石成分和砂岩碎屑组成的统计分析结果显示,多尼组沉积组合中的碎屑组成主要来自蛇绿岩、中酸性岩浆岩、沉积岩和少量变质岩。砂岩重砂矿物组合和古水流分析结果表明,...
Article
The Meso-Tethys Ocean was mainly represented by the Bangong-Nujiang suture zone between the South Qiangtang and Lhasa terranes in the Tibetan plateau. The subduction polarity of this Tethys Ocean during the Mesozoic is still being debated and it has been suggested to be northward or bidirectional subduction. A series of volcanic rocks, including an...

Sedimentary successions provide direct evidence of climate and tectonics, and these give clues about the causes of the mass extinction around the Permian–Triassic boundary. Terrestrial Permian–Triassic boundary strata in the eastern Ordos Basin, North China, include the Late Permian Sunjiagou, Early Triassic Liujiagou and late Early Triassic Heshan...

The causes of the severest crisis in the history of life around the Permian-Triassic boundary (PTB) remain controversial. Here we report that the latest Permian alluvial plains in Shanxi, North China, went through a rapid transition from meandering rivers to braided rivers and aeolian systems. Soil carbonate carbon isotope (δ13C), oxygen isotope (δ...

The closure of the Bangong–Nujiang Tethyan Ocean (BNTO) and consequent Lhasa–Qiangtang collision is vital to reasonably understanding the early tectonic history of the Tibetan Plateau before the India-Eurasia collision. The timing of the Lhasa–Qiangtang collision was mainly constrained by the ophiolite and magmatic rocks in previous studies, with o...
Article
This study covers cosmic spherules derived from the Mesoproterozoic Dahongyu Formation in the Ming Tombs area, Beijing. The cosmic spherules include iron oxide cosmic spherules, carbonaceous chondrites, and atomic iron “steely bead”‐shaped cosmic spherules. The mineral assemblage of silicon carbide, forsterite, zircon, and glass spherules and fragm...

The North Lhasa terrane in Tibet is generally interpreted to be paleotectonically unrelated to the East African Orogen (EAO) and is instead thought to have derived from northeastern India or northwestern Australia. In this study, we present petrogenetic and geochronological results pertaining to the analysis of gabbros (ca. 652 Ma), diorites (ca. 6...
Article
The origin and evolution of the Precambrian North Lhasa Terrane in the central Tibetan Plateau remain enigmatic. Here we present U–Pb age and Hf isotopic data for detrital zircons from early Neoproterozoic quartzites in the North Lhasa Terrane, Tibet. An integrated petrological, geochronological, geochemical, and Sr–Nd–Hf isotopic study was also un...
Article
The North and South Lhasa terranes in the central Tibetan Plateau were traditionally considered to be one block in the Precambrian and originate from the northeastern India or northern Australia. In this contribution, we report Middle Neoproterozoic (ca. 760 Ma) gabbros in the North Lhasa terrane. The gabbros can be subdivided into two groups. The...
