“…Such a scenario is in good agreement with the recent proposition for the genesis of the $435 Ma gabbros and diabases within the SCB (Wang et al, 2013c). Indeed, similar observations have been used to infer lithosphere removal in other mountain belts, such as the Tibetan Plateau (e.g., England and Houseman, 1989;Jiménez-Munt et al, 2008), East Anatolian Plateau (e.g., Keskin, 2003;S ßengör et al, 2003), Eastern Carpathians (e.g., Knapp et al, 2005;Fillerup et al, 2010), Adirondack Mountains (e.g., McLelland et al, 2010), Sierra-Nevada region (e.g., Ducea and Saleeby, 1998), and Variscan orogen (e.g., Gutiérrez-Alonso et al, 2011), suggesting that this is an important process in orogen evolution.…”

“…Therefore, it appears that, besides a high angle of underthrusting, some other factors co-control the generation of intermediate depth-focused earthquakes. Models indicate that the geometry of the underthrusts in the Indian and Eurasian plate in the northwestern Himalaya is significantly different from that of the central and eastern Himalaya (Jimenez-Munt et al 2008). The model uncertainties related to the geometry and physical properties are expected to decrease considering the constraint from the seismological model.…”

The differences in the tectonic regimes of the western part of the India -Asia collision zone (western Himalayan syntaxis), consisting of the Ladakh-Karakoram, Hindu Kush and Pamir terrains, are examined through the analyses and modelling of gravity anomalies, computed from global gravity model and terrestrial data. Long-wavelength (.450 km) anomalies are related to isostatic compensation and correspond to topographic variations. The short-wavelength gravity highs are primarily due to upthrust blocks and are mostly linked to crustal seismicity. The intermediate depth-focused earthquake region of Hindu Kush-Pamir is characterized by a gravity low probably caused by crustal underthrusting. The deep density structure of the crust and upper mantle constructed from the modelling of gravity anomalies with constraints from seismological information suggests crustal underthrusting of the Indian and the Asian plates in the Hindu Kush-Pamir section unlike that in the Ladakh-Karakoram region, where underthrust Indian lithosphere underplates beneath the Asian plate. The density model supports a hypothesis of slab breakoff of Indian and Eurasian plates in the Ladakh-Karakoram segment, and of the Indian plate in the Hindu Kush-Pamir region, whereas the Eurasian plate drastically underthrusts deeper (c. 200 km), causing deep seismicity in the Hindu Kush-Pamir section.

“…They are in general agreement with values given in the lithospheric modeling by TORNÉ et al (2000) and by FULLEA (2008). For the lower crust we have chosen relatively high values for the density, consistent with values commonly used for the lithospheric modeling of orogenic zones (e.g., JIMÉNEZ-MUNT et al, 2008) or for numerical models of evolution of orogens (e.g., SCHOTT and SCHMELING, 1998). To avoid the numerical complexities associated with dealing with numerous bodies, we have adopted the same density values in the non-perturbed zone.…”

Convective removal and mantle delamination are geodynamical mechanisms proposed to explain the presence of extension in the Alboran Sea within a regional context of compression. Using a new thermomechanical algorithm, we present here a quantitative evaluation and comparison of conceptual models based on these geodynamical mechanisms. In contrast to the in situ convective removal process, the laterally propagating delamination mechanism is shown here to be consistent with first-order features of the Alboran Sea such as the thinning/thickening distribution, intermediate-depth seismicity and upper mantle structure imaged by seismic tomography. The lower crust is predicted to reach depths of 100-150 km in some areas, due to mechanicallydriven viscous drag of the downwelling mantle.
