We obtain P-wave receiver functions from teleseismic earthquake recordings at a dense seismic broadband transect, deployed along 170 km across the Betic mountain range in southeastern Spain. Migrated images show crustal structure of orogen detail. In particular, they reveal situation subducted Iberian paleomargin, with full preservation proximal domain and ?50 wide necking domain. Crustal thinn...

We perform geomorphological analysis and modeling of the Lagrangian satellites Dione Tethys, based on images obtained by Cassini's Imaging Science Subsystem camera a digital elevation model covering Helene's Saturn-facing leading sides. cratered surface has been heavily modified mass flows as indicated pronounced crater rim degradation downslope-oriented chutes, ridges mesas, which reach >5 km ...

The evolution of the Tethys Ocean has received much research attention; however, timing and subduction mechanisms involved in closure Bangong-Nujiang Meso-Tethys remain poorly constrained. In this study, we present geological, geochronological, geochemical, zircon isotopic data from Cretaceous magmatic rocks combine these with previously published within central suture zone north-central Tibeta...
