Anelastic properties beneath the Niigata–Kobe Tectonic Zone, Japan
We estimate the three-dimensional (3D) P-wave attenuation structure beneath the Niigata–Kobe Tectonic Zone (NKTZ), central Japan, using high-quality waveform data from a large number of stations. The obtained results confirm the segmentation of the NKTZ into three regions, as suggested by 3D seismic velocity models, and reveal characteristic structures related to surface deformation, shallow su...
متن کاملRole of supra-subduction zone ophiolites in the tectonic evolution of the southeastern Zagros Orogenic Belt, Iran
Ophiolitic rocks in the southeastern part of the Zagros Orogenic Belt can be separated from southwest to northeast, into two groups: the Neyriz ophiolites and the Naien–Shahrebabak–Baft ophiolites. The southeast sector of Sanandaj-Sirjan wasdelimited by the two nearly synchronous ophiolitic belts in its southwestern and northeastern margins. In this study, new ophiolitic formation models were u...
متن کاملTectonic Setting of Metabasites of the Neo-Tethyan Oceanic Remains in Sanandaj-Sirjan Structural Zone West of Isfahan, Central Iran
The study area is located in the western portion of Isfahan, in Shahrekord-Dehsard Terrene. This area is part of the Sanandaj- Sirjan structural Zone. In this area, metamorphosed igneous outcrops contain greenschist and metabasite rocks. These rocks have metamorphed into greenschist facies and belong to the Triassic-Jurassic age. The etabasite is mainly composed of plagioclase, amphibole, epido...
متن کاملA tectonic model for Cenozoic igneous activities in the eastern Indo^Asian collision zone
Geochronologic dating and compilation of existing age data suggest that Cenozoic activities in the eastern Indo^ Asian collision zone of southeast China and Indochina occurred in two episodes, each with distinctive geochemical signatures, at 42^24 Myr and 16^0 Myr. The older rocks are localized along major strike^slip faults such as the Red River fault system and erupted synchronously with tran...
متن کاملTectonic evolution of a continental collision zone: A thermomechanical numerical model
[1] We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale viscoplasto-elastic thermomechanical model that has a free upper surface, accounts for erosion and deposition and allows for all modes of lithospheric deformation. For quartz/olivine rheology and 60 mm/yr convergence rate, the continental subduction...
