Fault-controlled regional magmatism and mineral deposition in central Cathaysia—Evidence from ambient noise tomography
Guangdong Province in the central Cathaysian Block has two world-class metallogenic belts, namely, the Nanling and Southeastern Coastal Metallogenic Belts (NLMB and SCMB), which are spatially coincide with the...

Crustal velocity structure of the Northwest Sub-basin of the South China Sea based on seismic data reprocessing
The deep crustal structure of the Northwest Sub-basin (NWSB) of the South China Sea (SCS) is of great importance for understanding the tectonic nature of the continent-ocean transition (COT) and magmatism in t...

The Cenozoic activities of Yangjiang-Yitongdong Fault: insights from analysis of the tectonic characteristics and evolution processes in western Zhujiang (Pearl) River Mouth Basin
The Yangjiang-Yitongdong Fault (YJF) is an important NW-trending regional fault, which divides the Zhujiang (Pearl) River Mouth Basin (ZRMB) into western and eastern segments. In Cenozoic, the northern contine...

Relocation of two earthquakes in the Southwest Indian Ridge area combining land seismic stations’ with OBSs’ data
Two earthquakes were recorded by 20 ocean bottom seismometers (OBS) deployed in the Southwest Indian Ridge (SWIR) area during a three-dimensional seismic survey in 2010. Their magnitudes (both M ...

The role of rifting in the development of the continental margins of the southwest subbasin, South China Sea: Insights from an OBS experiment
The continental margins of the southwest subbasin in the South China Sea mark a unique transition from multi-stages magma-poor continental rifting to seafloor spreading. We used reflection and refraction profi...

Segmentation of the Manila subduction system from migrated multichannel seismics and wedge taper analysis
Based on bathymetric data and multichannel seismic data, the Manila subduction system is divided into three segments, the North Luzon segment, the seamount chain segment and the West Luzon segment starts in So...

Seismic phases from the Moho and its implication on the ultraslow spreading ridge
The Moho interface provides critical evidence for crustal thickness and the mode of oceanic crust accretion. The seismic Moho interface has not been identified yet at the magma-rich segments (46°–52°E) of the ...

Characteristics of PmP phases from earthquakes and their role in crustal tomography: An active volcanic area example, northeastern Japan
Later earthquake-sourced PmP phases have the potential to significantly improve ray coverage and resolution of crustal tomography methods, as their trajectories are quite different from those of shallower P ph...

Research on the dynamics of the South China Sea opening: Evidence from analogue modeling
Independent of Indochina extrusion, the South China Sea experienced a process from passive continental rifting to marginal sea drifting. According to the fault patterns in the Beibu Gulf basin and the Pearl Ri...

Characteristics of the mantle source region of sodium lamprophyres and petrogenetic tectonic setting in northeastern Hunan, China
A set of unique sodium lamprophyres is developed in the Cenozoic intraconti-nental extensional zone of northeastern Hunan. These lamprophyres are significantly different in major and trace elements and Sr, Nd ...
