The aim of this project is to study the present lithospheric structure of three anomalous regions along the Alpine-Himalayan belt: The Atlas, Tibet and the Zagros mountains.
>Geosciences in Iberia: Integrated studies of topography and 4-D evolution ‘Topo-Iberia’
Topo-Iberia is a proposal that involves more than 100 PhD researchers from 10 different groups. It corresponds to the willingness and interest of the Spanish scientific community to establish an integrated framework to develop multidisciplinary geoscientific studies in our country. The ‘micro-continent’ formed by the Iberian Peninsula and its margins constitutes a most suitable natural laboratory, well identified by the international scientific community, to develop innovative, frontier research on its topography and 4-D evolution. The objective of Topo-Iberia is to understand the interaction between deep, surficial and atmospheric processes, by integrating research on geology, geophysics, geodesy and geotechnology.
The knowledge on the relief changes and its causes is of great social impact concerning the climate change and the evaluation of natural resources and hazards. Three major domains of research have been identified: the southern and northern borders of the Iberian plate (the Betic-Rif system and the Pyrenean-Cantabrian system) and its central core (Meseta and Central-Iberian systems). It is intended to build up a comprehensive, multidisciplinary base of data and results to tackle the key existing questions by developing novel interpretation strategies. A major aim of this programme is to significantly increase the high-quality information available, by deploying a technological observatory platform, IberArray, of high resolution multisampling. With this programme, our community could join the leading edge of international research, marked by similar initiatives, such as TopoEurope/EuroArray in Europe or the ongoing US programme Earthscope.

Estructura sísmica de la corteza bajo la cordillera del Rif
The basic aim of the project is to characterize the crustal structure in the Northern part of Morocco, especially beneath the Rif Cordillera, based on the acquisition of new wide-angle seismic profiles and on the integration of the various seismic data sets now available. In this way we envisage to overcome one of the marked failures existing at present to constrain any evolutionary model of the complex interaction zone between the European and African plates: the lack of reliable results on the architecture of the crust in the southern flank. The proposal involves the recording of three profiles of wide-angle reflection/refraction seismics, through the internal and external units of the Rif Cordillera and their transition to most eastern domains and to the Atlas. In all these transects, whose length oscillate between 250 and 300 km, seismic stations will be installed with a density of one instrument per 750-1000 m, and 3 to 4 shots will be fired throughout each profile. The high amount and density of new data will allow building up models of internal distribution of seismic velocities that document the crustal structure and its lateral variations. This information can be regarded as a `missing link' among a series of recently acquired data sets in diverse projects.
In addition, this proposal has a clear added value: to benefit from synergies already established between research groups to maximise and improve the results from various studies. The RIFSIS design envisages also to integrate all the seismic information available coming from both present projects as SIMA (Active seismics in the Atlas), SIBERIA (passive seismics in South Spain-North Morocco) and TOPOIBERIA (multidisciplinary studies and networks covering the whole Peninsula), and previous projects (ESCI-Betics-Alboran, seismic refraction in Betics, etc.). For this purpose: a) the data analysis of the broadband seismic network deployed in the northern part of Morocco will be completed, and b) we plan to maintain this network operative during the first semester of 2010, beyond the conclusion of its impelling project, SIBERIA (October of 2009), to coexist with the deployment of an OBS network in Alboran during that period (project TOPO-MED). This will allow to profit from previous efforts and improve/complete the results of regional seismicity and seismotectonics, deep structure by studying conversion of P and S waves, mantle anisotropy and tomographic inversion from different types of waves and at different scales. In this later case, the constraint on the crustal structure from the seismic profiles will be of great importance, and will be integrated to approach the regional mantle tomography. The geodynamic implications of all new results will also be discussed.

Procesos de colisión Arco-Continente en Taiwan
The project PROTAI will integrate new surface geological observations with passive-source (earthquake) seismic data to study the crustal structure, physical properties (Vp, Vs, density) and the tectonic processes in the active arc-continent collision that is taking place between the Luzon arc and the continental margin of Eurasia in Taiwan. Research on the Taiwan orogen will be integrated with the results of previous research of the group into arc-continent collision in fossil orogens, as well as with its research into petrophysical properties of the curst and upper mantle. The research is focused into three main themes:
• Crustal structure. Determine the crustal structure on the Taiwan orogen from the active frontal thrusts of the Western Foothills to the accreting forearc in the Coastal Range in the east. Detailed structural mapping combined with geophysical data, in particular seismicity, will provide information on the response of the extended continental margin as it enters the subduction zone.
• Tomography and petrophysical modeling of the Taiwan crust using Vp and Vs velocities, and potential field data. This provides important information about the composition of the crust and its physical properties. These properties are important in determining the fate of the continental crust as it is subducted.
• Determining geodynamic processes. The end result of this research is to develop a model for the geodynamic processes that take place during arc-continent collision. The processes include, but are not restricted to; crustal recycling through the subduction factory and how this influences the growth of new continental crust, determining the timing and extent of vertical and horizontal movements along faults in the thrust belt and the subsequent evolution of topography.

Tectonic-climatic interactions in arid orogen-basin systems
Arid climate within some orogens such as the Zagros Mountains is a phenomenon that modifies the balance between the tectonic processes that generate topography and the erosion/transport processes that remove it. Sediment trapping in intramountain basins can modify the evolution of tectonic deformation. Inversely, it is well known that arid climate results from the topographic blockage of incoming humid wind into the orogen (orographic precipitation).
In this project we aim at investigating the mechanisms involved in this feedback between climate and tectonics by means of numerical modelling techniques constrained with multidisciplinary observations, mostly collected from our own work and existing publications.
We will perform a combined numerical modeling of the processes controlling the evolution of intramountain basins and the mechanisms by which these basins become exorheic and are drained and eroded out of the orogen. We will address geological escenarios where numerous recent data on tectonics and sedimentation have been collected and where an effort in the large-scale tectonosedimentary evolution has already been done. Suitable systems are the Zagros-Persian Basin system; the Carpathian-Pannonian Basin system, and the Cenozoic intramountain basins of Iberia.
The main outcomes expected are a new method for estimating erodibility from overtopping basins and a better understanding of the processes controlling the evolution of topography during orogenesis and their relative importance.
