Lithospheric deformation of the Tibetan plateau is caused by subduction Indian (northward) and Asian (southward) plates. The effects this interaction on inner reaches continent, between North China craton (NCC) for example, remain uncertain due to poor geophysical data coverage in northeastern Tibet (NE Tibet). We provide here detailed knowledge lithospheric structure beneath NE as determined from a dense broadband seismic profile traversing westernmost NCC. Receiver function imaging reveals...
Abstract The Namche Barwa massif (NBM) in the Eastern Himalayan Syntaxis (EHS) hosts some of most active Cenozoic crustal deformation, magmatism, metamorphism, and extreme topographic relief on earth. crust‐mantle dynamics responsible for tectono‐magmatism NBM remains debated. We image detailed structures under using recordings a dense seismic array 400 3‐component node geophones 4,290 P‐wave receiver functions (PRFs). Our results show wide range negative phases middle lower crust weak Moho...
Abstract Xinfengjiang Water Reservoir (XWR), located in the northeast of Guangdong Province, South China, has hosted a large number earthquakes since its impoundment. In order to understand potential triggering mechanisms reservoir‐induced seismicity that could help assess seismic hazard Greater Bay Area, most populated region this study, we construct high‐resolution shear‐wave velocity model shallow crust at depths from surface ∼10 km based on high‐density short‐period array recently...
Abstract We used teleseismic body waves recorded at stations of the Chinese Center Digital Seismic Network to map upper mantle discontinuities beneath continental China. The CRUST2.0 and an S -tomography model each station were combined with one-dimensional tracing method convert time series radial receiver functions depth series. Clear signatures corresponding 410- 660-km (‘410’ ‘660’) are visible almost all stations. average velocity contrast ‘410’ study area is close global average, but...
Abstract Detailed seismic structure in the crust beneath northeastern margin of Tibetan Plateau was revealed by receiver functions a regional permanent network. At most stations, negative P‐to‐S converted phases can be detected radial functions, prior to Moho phases, indicating low velocities midlower crust. Prominent azimuthal variations transverse with polarity reversal suggest anisotropy We used time at and azimuth‐weighted stacking determine fast direction magnitude anisotropy. The...
Abstract Global stacks of receiver functions clearly exhibit the upper mantle stratification. Besides most prominent seismic discontinuities, such as Moho and 410 660 km a negative discontinuity is detected at depth ~600 km, indicating low‐velocity layer base transition zone. The slant‐slack technique helps to identify primary conversions from multiple reverberations. Presence 600 underneath both continent ocean island stations, where crustal thickness significantly differs, also precludes...
Abstract Continental rejuvenation results from the tectonic reactivation of crustal structures and lithospheric reworking by mantle flow. Geochemical observations field mapping have traditionally provided primary evidence for secular evolution composition processes during continental rejuvenation. Nonetheless, impact on observed present-day strain rate orogenic-scale structure has not been well constrained. The pre-existing E-W–trending Central China Orogenic Belt overprinted N-S–trending...
Abstract Large earthquakes that occur away from plate boundaries (i.e., large intraplate earthquakes), though rare, could cause heavy damage. Understanding their causes help with seismic hazard assessment. In this study, we image the seismogenic structure under 1969 Ms6.4 Yangjiang earthquake within stable South China Block a high‐resolution three‐dimensional shear‐wave velocity model constructed ambient noise tomography based on dense nodal array. The images relatively low velocities at...
Abstract Teleseismic receiver functions are used to estimate the crustal thickness, V P and / S (or Poisson’s ratio, δ ) beneath northeastern margin of Tibetan Plateau. Surface-wave dispersion measurements combined with teleseismic improve estimates model parameters. A migration method based on a local velocity is image upper-mantle discontinuities. According location pierce points direct converted phases observed functions, we topography The thicker crust in Altyn Tagh fault–Hexi Corridor...
Accurate determination of the seismometer orientation is a prerequisite for seismic studies including, but not limited to anisotropy. While borehole seismometers on land produce waveform data somewhat free human-induced noise, they might have drawback an uncertain orientation. This study calculates harmonic decomposition teleseismic receiver functions from P and PP phases determines by minimizing constant term in expansion tangential backazimuth near at 0 s. method normalizes effect sources...
