INDEPTH geophysical and geological observations imply that a partially molten midcrustal layer exists beneath southern Tibet. This has been produced by crustal thickening behaves as fluid on the time scale of Himalayan deformation. It is confined south structurally imbricated Indian crust underlying Tethyan High Himalaya underlain, apparently, stiff mantle lid. The results suggest during Neogene underthrusting acted plunger, displacing middle to north while at same contributing this melting...
Abstract The tectonic dynamics of the Lhasa‐Gangdese terrane, southern Tibet, are still unclear and open questions persist regarding structure, physical properties, rheology lithosphere. A three‐dimensional electrical resistivity model was generated beneath Lhasa 79°−94°E 28°–33°N, an area ∼1,500 by ∼600 km, using data from 537 magnetotelluric measurements. To overcome computational challenges, we present approach in which multiple high‐resolution models overlapping subregions combined means...
Abstract Crustal flow is an important tectonic process active in continent‐continent collisions and which may be significant the development of convergent plate boundaries. In this study, results from multidimensional electrical conductivity modeling have been combined with laboratory studies rheology partially molten rocks to characterize rheological behavior middle‐to‐lower crust both Songpan‐Ganzi Kunlun terranes northern Tibetan Plateau. Two different methods are adopted develop...
Abstract The ongoing India‐Asia collision since the Paleogene created Tibetan Plateau, most prominent elevated plateau on our planet. This convergence also contributed to formation of two distinct types active surface deformation plateau, namely, north–south trending normal fault systems and “conjugate” strike‐slip systems. tectonics geodynamic mechanism(s) behind this curious combination are still unclear, despite numerous theories proposed over past decades. Here we present a new...
Both low resistivity zones and velocity are distributed in the middle-lower crust of western Lhasa terrane, Tibetan Plateau, China. Some estimates from electrical data suggest large volume fractions silicate melts that difficult to reconcile with seismic prefer lower volumes. A second conductive phase, such as saline fluids, drastically reduces conductivity but does not significantly affect because its may be able explain these differences. In this study, a 3-D model structure is generated...
New evidence worldwide has linked the surface locations of mineral deposits and their crustal-scale electrical conductivity footprint. We examine relationship between Gangdese Miocene porphyry copper deposits, Tibetan Plateau, signature from a three-dimensional model generated 311 magnetotelluric measurements. The distribution resistivity throughout crust conductance within mid-lower (depth range 25–70 km) is analyzed. results clearly show that large ultra-large coincide spatially with...
Abstract The Xainza‐Dinggye rift, an approximately north‐south trending Cenozoic fault zone across the Lhasa Terrane, is ideal location to investigate extensional mechanisms in upper crust and lithospheric deformation caused by subducting Indian Plate beneath central‐southern Tibetan Plateau. 3‐D electrical resistivity structure was obtained modeling magnetotelluric data from array rift zone. Using temperature distribution throughout combined with pressure water content, we compute pure melt...
Abstract A weak middle crust induced by fluid phases is generally considered to exist beneath the Himalayan‐Tibetan orogen; however, there remains controversy regarding interpretation of high‐conductivity and low‐velocity regions imaged in various geophysical studies. To better understand crustal rheological behaviors associated triggering mechanisms southern Tibet, we present a geoelectrical model derived from three‐dimensional magnetotelluric inversion this study. An effective conductivity...
In the southern Tibetan plateau, which is considered to be ongoing India–Eurasia continental collision zone, tracing of Indian crustal front beneath Tibet still controversial. We conducted deep subsurface electrical modeling in and discuss geometry crust. Three areas along Yarlung-Zangbo river zone for previous magnetotelluric (MT) data are available were inverted independently using a three-dimensional MT inversion algorithm ModEM. Electrical horizontal slices at different depths...
Abstract In the southern Huanghai (Yellow Sea), seismic exploration for oil and gas in pre‐Tertiary strata encounters some difficulties, such as poor geological conditions at depth, screened waves, serious attenuation of energy, so that reflective signals from Mesozoic Paleozoic systems cannot be recognized. To solve this issue by other approach, an experiment seafloor magnetotelluric (MT) sounding was carried out region May 2006. This work has deployed 3 measurement sites on Wulian slope...
Abstract To study the structure in shallow and deep crust along east‐west north‐south direction beneath Yarlung Zangbo Jiang suture southern part of Tibetan plateau, three magnetotelluric profiles with super‐wide band frequencies (Cona‐Maizhokunggar, Yadong‐Xuegula, Gyirong‐Coqên) across were deployed. The result shows that large‐scale high resistive bodies exist near surface, which extend to maximum depth more than 30km. They are reflection Gangdise granite. There small‐scale conductive...
Abstract Based on magnetotelluric (MT) sounding along the three profiles across Bangong‐Nujiang suture in Tibet, we have established electric model for this tectonic zone and adjacent areas studied features of deep structure region. The result shows that there exist widespread discontinuous high‐resistivity bodies upper crust its both sides, which reflect spatial distribution magmatic rocks exhibits big difference between northern southern sides. Beneath Gangdisê Qiangtang terranes, middle...
The Tethys-Himalaya terrane in the north of Himalayan orogenic belt is characterized by pervasive extensional structures such as N–S-trending normal rifts and North Gneiss Dome (NHGD). Dinggye region located central part terrane. southern segment Xainza-Dinggye rift (XDR) Mabja are distributed this region. In work, we generate a new 3-D electrical resistivity model from an array magnetotelluric data examine it addition to other models east previous works. By comparing geophysical with...
Located in the central part of Tibetan Plateau, Qiangtang terrane preserves important record uplift and deformation history therefore remains an attractive area research. However, deep geophysical investigations its western are still limited. Here we present a new 3-D crustal electrical model surrounding area, computed from magnetotelluric array data. The structure suggests Longmu Co-Gozha Co fault, once believed to be major regional boundary, may not have cut crust. melt content rheological...
To help address the occlusion problem in panoptic segmentation and image understanding, this paper proposes a new large-scale dataset, COCO-Occ, which is derived from COCO dataset by manually labelling images into three perceived levels. Using we systematically assess quantify impact of on samples having different levels occlusion. Comparative experiments with SOTA models demonstrate that presence significantly affects performance higher resulting notably poorer performance. Additionally,...
