We have compiled the distribution of active faults and folds in the HimalayanTibetan orogen and its immediate surrounding regions into a web-based digital map. The main product of this study is a compilation of active structures that came from those documented in the literature and from our own interpretations based on satellite images and digital topographic data. Our digital tectonic map allo...

The Nam Pat Group of the Nam Pat Basin, Uttaradit Province, Thailand is situated in the Nan Suture Zone. Two contrasting tectonic framework models of the Nan Suture have previously been proposed: as a main Paleo-Tethyan suture and as a remnant of a closed back-arc basin. The goal of this study is to analyze the tectonic framework of the Nan Suture and reevaluate the existing tectonic models. Th...

Introduction: Grooved terrain on Ganymede generally occurs as individual lanes and polygonal crosscutting swaths of bright terrain. Internally, grooved terrain swaths consist of parallel to sub-parallel ridges and troughs at a variety of scales (Fig. 1); the ridges and troughs show generally similar morphology, size, and orientation. Grooved terrain on Ganymede has been interpreted by most auth...

[1] Mature fault zones appear to be weaker than predicted by both theory and experiment. One explanation involves the presence of weak minerals, such as talc. However, talc is only a minor constituent of most fault zones and thus the question arises: what proportion of a weak mineral is needed to satisfy weak fault models? Existing studies of fault gouges indicate that >30% of the weak phase is...

[1] Vesta’s large southern hemisphere impact basin is likely to have caused reorientation. However, because the basin is not centred at the south pole, Vesta likely also has a remnant rotational figure. Reorientation of ≈6° is predicted to have occurred based on the dimensions of the basin. Existing measurements of Vesta’s shape are consistent with ≈20° or less reorientation, and ≈20% or less d...

Abstract We investigated interactions between structural deformation and surface processes in the Longmen Shan fold‐and‐thrust belt adjacent western Sichuan foreland basin (WSFB) eastern margin of Tibetan Plateau. The discrete‐element modeling (DEM) method was used to study influences various mechanical properties detachments syn‐tectonic erosion/deposition on evolution WSFB. DEM simulations de...

CHAMP and Swarm satellite magnetic data are combined to establish the lithospheric magnetic field over the Tibetan Plateau at satellite altitude by using zonal revised spherical cap harmonic analysis (R-SCHA). These data are integrated with geological structures data to analyze the relationship between magnetic anomaly signals and large-scale geological tectonic over the Tibetan Plateau and to ...

In the mid‐1980s, advances in understanding the mechanics of the fold‐and‐thrust belts that flank many collisional mountain ranges set the stage for a fundamental change in our appreciation of the role of erosion in the tectonic evolution of mountain ranges. A combination of sandbox experiments, analytical treatments of stress state and field observations showed that fold‐and‐thrust belts form ...

a r t i c l e i n f o Plate tectonics is a self-organizing global system driven by the negative buoyancy of the thermal boundary layer resulting in subduction. Although the signature of plate tectonics is recognized with some confidence in the Phanerozoic geological record of the continents, evidence for plate tectonics becomes less certain further back in time. To improve our understanding of ...
