S U M M A R Y We present the evidence for an anomalous southwest-dipping slab in southern Mexico. The main evidence comes from a clear receiver function image along a seismic line across the Isthmus of Tehuantepec and is also supported by a previous global tomographic model. The slab dips at 35◦, is approximately 250 km in length and appears to truncate the Cocos slab at about 120 km depth. We ...

Two hundred km of 2D seismic survey was carried out at the Lesser Himalayan Thrust Belts in Dailekh district, western Nepal. The main motivation is to elucidate geologic relationship between known oil and gas seeps, subsurface structure, stratigraphy area. This a challenging task which from its extreme structural geological complexity such as thrust faulting, tight folding, steep dip layers, st...

deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...

A structural model is developed for the south-central Taiwan fold-and-thrust belt that shows consistency across an array of data types and marks important step forward in consideration geological hazards risks. Although there general agreement about regional scale geology Taiwan, are considerable differences interpretations its western belt. In this paper, we bring together results our previous...

Abstract: A simulation technology has been developed to predict the transmission efficiency of a metal pushing V-belt and pulleys that make up the drive system of a continuously variable transmission (CVT). When a CVT operates in an actual vehicle, pulley thrust pressure is adjusted by feedback control to maintain a speed ratio. This feedback control has been implemented, for the first time, in...

[1] The contemporary presence of the Puli Topographic Embayment within the Taiwanese thrust belt provides insight into processes that initiate and maintain a subcritical state in a thin‐skinned compressive wedge. Orogen‐scale analyses of Taiwan have succeeded in describing the processes and interactions that affect overall development of the thrust belt; however, relatively little is known abou...

[1] The development of topography within and erosional removal of material from an orogen exerts a primary control on its structure. We develop a model that describes the temporal development of a frontally accreting, critically growing Coulomb wedge whose topography is largely limited by bedrock fluvial incision. We present general results for arbitrary initial critical wedge geometries and in...

This research focuses on fracture networks in sedimentary rocks within the Umbria-Marche fold-and-thrust belt in the Northern Apennines, Italy. The aim of this research is twofold, namely to correlate the geometry of fracture networks with tectonic position and lithology and to correlate the orientation of fracture networks with the origination of a fold-and-thrust structure. The fold-and-thrus...

The geometry, kinematics and dynamics of fold-and-thrust belts are strongly influenced by the mechanical behaviour basal décollement. However, many also include mechanically weak lithologies such as evaporites marls or mudstones at different levels within shortened stratigraphy. dynamic evolution these thrust controlled both décollement units embedded overlying stratigraphic succession. In Zagr...
