During the Mesozoic, NE Asia experienced intense tectonic and magmatic activity, including closure of Mongol–Okhotsk Ocean (MOO), subduction demise Mudanjiang Oceanic Plate (MOP), continuous westward Paleo-Pacific (PPP). The evolution MOP remains highly contentious, particularly regarding its final timing polarity, warrants further investigation. Heilongjiang Complex (HLC), primarily distributed within Suture Zone (MSZ), which separates Jiamusi Songnen blocks, preserves key geological...

Abstract. On 5 June 2009, a catastrophic rockslide debris flow occurred at the crest of Jiweishan range, Chongqing Municipality, China, killing 74 people and injuring an additional eight. We use L-band ALOS/PALSAR imagery to address landslide processes before, during after slide. employ three different SAR methods, i.e., short baseline subsets (SBAS) interferometric (InSAR), backscattering intensity change, InSAR stacking algorithm, study any ground deformation before rockslide, investigate...

The effective removal of oxytetracycline hydrochloride (OTC) from the water environment is great importance. Adsorption as a simple, stable, and cost-effective technology regarded an important method for removing OTC. Herein, low-cost biochar with developed mesoporous structure was synthesized via pyrolysis poplar leaf potassium bicarbonate (KHCO3) activator. KHCO3 can endow abundant mesopores, but excessive cannot continuously promote formation structures. In comparison all prepared...

Two-dimensional seismic and gravity-magnetic data were processed interpreted by the authors in order to study temporal spatial distribution of igneous rocks East China Sea Shelf Basin its adjacent regions.Data from land,mainly Zhejiang Fujian provinces collected for purpose correlation.Igneous are widely distributed Fujian.They occur a NE trending north NNE south 28 N.They shallowly buried controlled mainly major faults.The offshore upon uplifts or along fault boundaries...

Abstract The East China Sea Shelf Basin (ECSSB) is a typical Meso‐Cenozoic superimposed basin characterized by different tectonic frameworks, suffering multi‐stage tectonism (e.g. the Indosinian, Yanshanian and Himalayan) since Mesozoic. Mesozoic ECSSB key place to our understanding of evolution dynamic mechanism in eastern South subduction Izanagi Plate. Based on geological geophysical results acquired over last 10 years, this paper provides summary distribution strata, ascertains...

The Southern East China Sea Shelf Basin is a Mesozoic-Cenozoic superimposed basin developed on the pre-Mesozoic basement at junction of Eurasian,Pacific and Indian plates.It has experienced deformations Jilong,Yushan Yandang movements tectonic evolution obviously influenced by both subduction Paleo-Pacific plate Thethys-Himalayas Tectonic Domain.Studies Mesozoic igneous events,basin deformation,sedimentology comparative study between land sea have been carried out in this region.Results...

Based on the latest re-processed and newly acquired seismic data using integrated approaches including seismic,well drilling,inverse gravity magnetic processing land sea correlation,we studied distribution of Mesozoic in southern East China Sea Shelf Basin,and got some new understandings about three uplifts,namely Yandang,Taibei Guanyin uplifts,defined by previous studies.It is found that Yandang Uplift fact not a continuously uplift from north to south,but an old Proterozoic made up en...

Abstract The East China Sea Shelf Basin (ECSSB) is located on the south‐eastern edge of Eurasian Plate. tectono‐evolution and dynamic mechanism ECSSB are related to collision Pacific Plate with Plate, remote pushing effect Indo‐Australian remains a hot topic debate. Based latest survey data, this paper mainly focuses evolution Mesozoic basin in by means assessing regional tectonic background, conducting structural physical simulation experiments, applying balanced geological section recovery...

Abstract. Fenwei basin, China, composed by several sub-basins, has been suffering severe geo-hazards in last 60 years, including large scale land subsidence and small ground fissure, which caused serious infrastructure damages property losses. In this paper, we apply different InSAR techniques with SAR data to monitor these hazards. Firstly, combined baseline subset (SBAS) method persistent scatterers (PS) is used multi-track Envisat ASAR retrieve the covering entire from magnitudes are...

Abstract. Yuncheng area is one of the most extensive distributions ground fissures in Shanxi basin, especially Yanhu District Yuncheng, disaster and subsidence are serious. According to previous studies, development distribution this mainly controlled by underlying active faults. In order provide a better understanding formation mechanism, deformation its surrounding environment should be taken into consideration. paper, PS-InSAR technology was employed assess time-series with X-band...

Based on the data distribution pattern of Upper-Triassic strata in land area close to East China Sea and Ryukyu Island Arc,in combination with latest high-resolution seismic from area,It is inferred that Triassic may exist southern Sea,and contact overlying conformable or disconformable south unconformable north.The deposits were formed a deepwater environment,and there big potential for oil and/or gas generation.In this regard,the could be new important target oil-gas exploration.

High resolution multi-channel seismic survey is a cost-efficient technique for geological exploration.We conducted high with the SYNTRAK-480,and studied stratigraphical sequences in East China Sea Basin.Based on characteristics of reflection records retrieved from data,6 reflectors marked as T02,T03,T04,T05,T06 and Tg are recognized 6 established by correlation.From top to bottom,they Ⅰ(sea floor—T02),Ⅱ(T02—T05),Ⅲ(T05—T06),Ⅳ(T06—Tg)andⅤ(Tg —below),and second sequence can be further divided...

On 19 January 2020, an Mw6.0 earthquake occurred in Jiashi County, Xinjiang, China. This is a strong that the Kepingtage Belt. The monitoring and inversion of co-seismic post-earthquake will help further understand geometry movement properties this tectonic belt. In study, Sentinel-1A images were used to analyze deformation post-seismic events. Okada elastic dislocation model was invert geometric parameters fault slip distribution. results showed maximum uplift subsidence deformations from...

Current single image derain methods cannot solve the heavy rain situation well. In this paper, based on physical model of a rainy image, we build two-stage network, TSF-Net, which combines model-driven and data-driven methods. The first stage gets streaks, atmospheric light, transmission map to obtain coarse rain-free by model. second is fully convolutional neural network with structure U-Net. proposed Multi-Scale Projection Fusion Block (MSPFB) module, can perceive spatial information...
