[1] We introduce a new method that convolves detrital mineral cooling ages with digital elevation models to test numerical models of erosion in collisional orogens. Along a Trans-Himalayan transect in central Nepal, we develop a kinematic and thermal model to predict variations in bedrock cooling ages in modern Himalayan topography. The model assumes a thermal steady state and utilizes a simple...

Abstract Anisotropy of magnetic susceptibility can provide insights into strain distribution in models simulating fold-and-thrust belts. Models with layers sand and magnetite mixture shortened above adjacent decollements high low friction, are used to study the effect decollement friction on fabric. Above high-friction decollement, an imbricate stack produced a ‘tectonic’ fabric foliation paral...

We investigate the possibility to apply differential SAR interferometry (DIFSAR) techniques to analyse long term phenomena occurring in volcanic areas. The considered test site is represented by the Etna volcano area located in southern Italy; presented DIFSAR experiments show the existence of a long term deformation effect that can be interpreted as an actively growing anticline, beneath the u...

[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...

[1] The activity at Mauna Loa volcano, Hawaii, is characterized by eruptive fissures that propagate into the Southwest Rift Zone (SWRZ) or into the Northeast Rift Zone (NERZ) and by large earthquakes at the basal decollement fault. In this paper we examine the historic eruption and earthquake catalogues, and we test the hypothesis that the events are interconnected in time and space. Earthquake...

Introduction: Recent detections of phyllosilicate (clay) minerals in ancient terrains [1-3] have revolutionized our understanding of early hydrothermal activity on Mars. The spectral signatures of phyllosili-cates are seen exclusively in Noachian-aged outcrops and not in Hesperian or Amazonian materials [1-3]. Phyllosilicates are inferred to have been widely em-placed during a period of time (t...
