Mapping seismic anisotropy using harmonic decomposition of receiver functions: An application to Northern Apennines, Italy
[1] Isotropic and anisotropic seismic structures across the Northern Apennines (Italy) subduction zone are imaged using a new method for the analysis of teleseismic receiver functions (RFs). More than 13,000 P‐wave coda of teleseismic records from the 2003–2007 Retreating‐Trench, Extension, and Accretion Tectonics (RETREAT) experiment are used to provide new insights into a peculiar subduction ...

More than 13,000 P-wave coda of teleseismic records 10 from the 2003-2007 RETREAT experiment are able to reveal new insights 11 into a peculiar subduction zone which develops at the convergent margin of 12 two...
متن کاملThe subduction structure of the Northern Apennines: results from the RETREAT seismic deployment
The project Retreating-trench, extension, and accretion tectonics, RETREAT, is a multidisciplinary study of the Northern Apennines (earth.geology.yale.edu/RETREAT/), funded by the United States National Science Foundation (NSF) in collaboration with the Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) and the Grant Agency of the Czech Academy of Sciences (GAAV). The main goal of RE...
متن کاملIsostasy, dynamic topography, and the elevation of the Apennines of Italy
a r t i c l e i n f o a b s t r a c t The elevation of an orogenic belt is commonly related to crustal/lithosphere thickening. Here, we discuss the Apennines as an example to show that topography at a plate margin may be controlled not only by isostatic adjustment but also by dynamic, mantle-driven processes. Using recent structural constraints for the crust and mantle we find that the expected...
متن کاملFast Episodes of West-Mediterranean-Tyrrhenian Oceanic Opening and Revisited Relations with Tectonic Setting
Extension and calc-alkaline volcanism of the submerged orogen of alpine age (OAA) initiated in Early Oligocene (~33/32 Ma) and reached the stage of oceanic opening in Early-Miocene (Burdigalian), Late-Miocene and Late-Pliocene. In the Burdigalian (~20-16 Ma) period of widespread volcanism of calcalkaline type on the margins of oceanic domain, seafloor spreading originated the deep basins of nor...
