“…2011). The previous studies (Liu and Niu 2011;Gao and Li 2014;Pan et al 2014;Wei et al 2014) suggested that variations in crustal thickness apparently play an important role in controlling tectonic activity in the study region. Studies of the regional variations in crustal attenuation in Northeast China and the adjacent regions shows that the highest attenuation (low Q 0 values) is observed beneath the Songliao plain, which has thick sedimentary deposits and strong tectonic activity (Sun 2012).…”

“…The figures suggest the Changbaishan maybe a result of mantle material upwelling originated from depth near 700 km. The receiver function results shows obvious lateral variation in the upper mantle transition zone, which maybe result from mantle material upwelling (Liu and Niu 2011;Tang et al 2014). The geothermal gradient of the Songliao basin which has a high heat value, is slightly higher than that of other basins elsewhere in the world (Nie 2004).…”

“…Liu and Niu (2011) found that the crustal thickness varies from 27.9 km beneath the eastern flank of the Songliao basin to 40.7 km beneath the Da Hinggan Ling region and suggested there would be a mantle upwelling using tele-seismic receiver function method. Zhang et al (2013Zhang et al ( , 2014 found there is a high-velocity zone beneath the Songliao basin with some high-and lowvelocity anomalies using tele-seismic tomographic data.…”

“…The Songliao basin is commonly believed to be formed due to rifting in the Mesozoic Era (Hu et al 1998;Ren et al 2001;Liu and Niu 2011). In recent years, some studies have used tomography (P wave, Pn wave, S wave, and ambient noise), receiver functions, and S wave attenuation to reveal deep dynamic characteristics in the area (Zhao 2004;Lei and Zhao 2005;Sun 2012;Zhang et al 2013Zhang et al , 2014Pan et al 2014).…”

We selected relative travel-time residuals from teleseismic waveform data using the waveform correction method and imaged the P wave velocity structure beneath Northeast China. In combination with other geophysical data, we discussed the relation between the shallow and deep structures of the area. The results show that there is a primary high-velocity zone with some high-and low-velocity distribution characters beneath the Songliao basin.

“…The Tanlu Fault Zone, the main active strike-slip fault zone in eastern China, is believed to have facilitated the upwelling of asthenosphere and played an important role in the Mesozoic-Cenozoic thinning of the cratonic lithosphere (Liu & Niu, 2011;Xu et al, 2004). The central segment of the Tanlu Fault Zone in the Shandong area, hereinafter referred to as the YSFZ, is an important mobile tectonic zone in eastern China.…”

New images of shear wave velocity (VS) structure of the crust and uppermost mantle in the Shandong province of China are presented based on inversion of ambient seismic noise data from 47 broadband stations. Interstation Rayleigh wave phase‐velocity dispersion curves for periods of 1–40 s are obtained from noise cross correlations between stations. Two‐dimensional phase‐velocity maps at periods of 5–30 s are obtained by tomographic inversion of these dispersion curves, which are then inverted for 3‐D Vs heterogeneity to ~80‐km depth. Our results show clear indications of Moho uplift and crustal thinning beneath the northern segment of the Yishu fault zone and the Jiaobei uplift, thus providing seismological evidence for the steep geometry and deep penetration of the fault system. Instead of large‐scale, low‐velocity anomalies beneath eastern China as imaged by previous regional tomography, our high‐resolution Vs results reveal fine‐scale focused low‐velocity anomalies beneath the isolated Cenozoic basalts. There are strong spatial correlations between the narrow low Vs zones in the uppermost mantle and the thinned crust, as well as the locations of the isolated Cenozoic volcanism in the study area. Our results suggest that the asthenosphere upwelling possibly originating from the stagnant Pacific slab is focused into localized features at 50‐ to 80‐km depth that supply the isolated Cenozoic volcanoes of the eastern China continental margin.

Moho depth and crustal thinning in the Marmara Sea region from gravity data inversion

et al. 2017

The free‐air gravity in the Marmara Sea reveals that the low density of sedimentary basins is partly compensated in the lower crust. We compiled geophysical upper crust studies to determine the sediment basin geometries in and around the Marmara Sea and corrected the gravity signal from this upper crust geology with the Parker method. Then, assuming long wavelength anomalies in the residual gravity signal is caused by variations in the Moho topography, we inverted the residual to build the Moho topography. The result shows that the Moho is uplifted on an area greater than the Marmara Sea with a maximum crust thinning beneath the basins where the Moho is at about 25 km, 5 km above the reference depth. We then evaluated the Neogene extension by comparing the surface covered by our 3‐D thinned model with the surface covered by an unthinned model with same crustal volume. Comparing this surface with areal extension rate from GPS data, we found a good compatibility indicating that the extension rate averaged over the Sea of Marmara area probably remained close to its present‐day value during major changes of tectonic regime, as the incursion of the North Anatolian Fault system during the Pliocene leads to the establishment of the dominantly strike‐slip present‐day system. We also show that crustal extension is distributed over a wider domain in the lower crust than in the upper crust, and that this may be accounted for by a relatively minor component of lower crustal ductile flow.
