SHORT EPISODES OF CRUST GENERATION DURING PROTRACTED ACCRETIONARY PROCESSES: EVIDENCE FROM CENTRAL ASIAN OROGENIC BELT, NW CHINA [PDF]

Геодинамика и тектонофизика, 2017
continental crust but the spatial and temporal distribution of crust generation within individual orogens remains poorly constrained. Paleozoic (~540–270 Ma) granitic rocks from the Alati, Junggar and Chinese Tianshan segments of the Central Asian ...

The boundary between the Central Asian Orogenic belt and Tethyan tectonic domain deduced from Pb isotopic data [PDF]

, 2015
A detailed comparison of the tectonic features of Central Asian Orogenic belt (CAOB) and Tethyan Tectonic domain (TTD) is of great significance to our understanding of the origin of global orogenic systems.

P-wave velocity structure and implications for magmatism and metallogenesis in the southern Altaids: Constraint from wide-angle seismic data along the Altai-Eastern Tianshan traverse

Frontiers in Earth Science, 2023
Altaids in the Central Asian Orogenic Belt (CAOB) is one of the world’s largest orogenic belts containing mineral deposits. Together with the Junggar terrain they open an important window to study the Paleozoic tectonic evolution of the CAOB.

Mesoproterozoic juvenile crust in microcontinents of the Central Asian Orogenic Belt: evidence from oxygen and hafnium isotopes in zircon. [PDF]

Sci Rep, 2018
We report in situ O and Hf isotope data of zircon grains from coeval Mesoproterozoic (ca. 1.4 Ga) igneous metamafic (amphibolite) and granitic rocks of the Chinese Central Tianshan microcontinent (CTM) in the southern Central Asian Orogenic Belt (CAOB ...

Timing the Hegenshan Suture in the Central Asian Orogenic Belt: New Paleomagnetic and Geochronological Constraints From Southeastern Mongolia

Geophysical Research Letters, 2023
The timing of formation of the Hegenshan suture is crucial to understanding the evolution of the Central Asian Orogenic Belt (CAOB). Here we present a well‐dated paleomagnetic pole (103 samples from 15 sites, 36.7°N/29.2°E, A95 = 3.3°) that passed a ...

Geological characteristics and genesis of the Late Carboniferous extremely thick slate in the Shuangjianzishan Ag-Pb-Zn district, southern Great Xing’an Range, NE China: constraints on metallogenesis and tectonic setting

Frontiers in Earth Science, 2023
The Shuangjianzishan super-large Ag-Pb-Zn deposit is situated in the southern Great Xing’an Range (SGXR), which is part of the eastern Central Asian Orogenic Belt (CAOB) and the northeastern Xing’an-Mongolia Orogenic Belt (XMOB).

Re-Evaluating A-Type Granite Petrogenesis: Formation during Ocean Opening [PDF]

Lithosphere
A-type granites are commonly emplaced in extensional settings, including post-collisional, intraplate, and back-arc environments. This study delves into the early Permian A-type granite and its felsic enclaves from the southern Beishan orogenic belt, a ...

Provenance and metamorphism of the Mesoproterozoic Baoyintu Group: Implication for the interaction between the western Central Asian Orogenic Belt and the North China Craton

, 2022
The deposition and metamorphism of the sedimentary rocks are closely related to the tectonic affinity and interactions among different terranes. The metasedimentary Baoyintu Group, which is distributed in the junctional area adjacent to the Alxa Block ...
