Tracing fluid dynamics with noble gas and stable isotope systematics : examples from Krafla, Iceland and Sichuan Basin, China
… in Krafla, Iceland and natural gases in the Sichuan Basin, China. Following a short introduction to the research background, objectives and thesis layout are presented in Chapter 1 and Chapter 2 gives a literature review on the application of noble gases as powerful geochemical tools in …

Assessing the Role of Solution Chemistry and Organic Matter in the Genesis of the Dengying Formation Dolostones at Sichuan Basin, China
… dolomite of the Dengying Formation, Sichuan Basin, China. Researchers debate the origin of dolomite with different data supporting a microbial model conflicting with late-state hydrothermal dolomite. This study tested the microbial model for dolomite formation in the Dengying using …

Natural Gas Generation Potential of the Wufeng-Longmaxi and Niutitang Shale Formations, Sichuan Basin, China: Insight from Hydrous and Anhydrous Pyrolysis
… and Cambrian Niutitang formations of the Sichuan Basin, China. Previous studies focused on geological variables affecting gas adsorption and retention in the Silurian and Cambrian shale systems. However, relatively few have investigated the gas generation potential of the source rocks …

LATERALLY HETEROGENEOUS SEISMIC ANISOTROPY INVESTIGATED BY SHEAR WAVE SPLITTING ANALYSES
… anisotropy beneath the northeastern edge of the Sichuan Basin in central China, and the spatial and temporal variations of anisotropy near the 2019 M7.1 Ridgecrest earthquake in California, respectively. A clear back azimuthal dependence of the splitting parameters and the lack of a 90° or 180° …

Sichuan fog -- architecture and moisture
… China. Surrounded by the nearby mountains of the Sichuan Basin, the city experiences year-long cloudiness as a result of temperature inversion caused by the basin's convective layer being capped by a layer of air moving east across the Tibet Plateau. Located at the confluence of Yangzte River and …

Seismic study of the crust and upper mantle structure in eastern Asia using ambient noise correlation and earthquake data
… slow upper crust but fast lower crust under Sichuan Basin, rapid Moho variation, and slow Pn in the plateau and fast Pn in the borderland separated by major boundaries and faults. The mid-lower crust in the plateau is relatively slow compared to the average model and Sichuan Basin and …

Tomographic inversion of Pn travel times in western China
… to the surface geology: (1) Four major basins bordering the Tibetan Plateau (TP) and/or Tien Shan (Tarim, Junggar, Qaidam, and Sichuan basin) display prominent high Pn velocities. These basins are tectonically stable with little deformation and lacking in seismic, thermal, and volcanic …

Ambient noise tomography for wavespeed and anisotropy in the crust of southwestern China
… with geology in the study region. In the Sichuan Basin, low wavespeed and positive radial anisotropy (Vsh> Vsv) in the upper crust reflect thick sedimentary layers at surface; high wavespeed and small radial anisotropy in the middle and lower crust reflect a cold and rigid basin root. …

Structural, thermal, and geomorphic evolution of the eastern margin of the Tibetan Plateau
… the Tibetan Plateau adjacent to and north of the Sichuan Basin poses a fundamental geodynamic problem; the topography of eastern Tibet apparently developed in the absence of significant shortening of the upper crust. This study investigates the development and subsequent evolution of the …

Controls on the distribution of landslides triggered by the 2008 Wenchuan earthquake, Sichuan Province, China
… mountain range, on the northwest margin of the Sichuan Basin. Landsliding contributed greatly to the high death toll of over 70,000 and widespread infrastructural damage produced by the earthquake. The event offers an opportunity to both broaden the global database of seismically induced …

Kinematics and Dynamics of Continental Deformation
… analogous to the relatively undeforming Sichuan Basin and Central Lowlands of Myanmar, can reproduce the main features of the present-day topography, GPS velocity field and earthquake-derived strain rate without the need for a low-viscosity lower-crustal channel.
