After the end of spreading South China Sea(SCS),an important structural movement-the Dongsha Movement took place at Northern Margin SCS.However,timing,range and dynamic mechanism is still unclear.Based on 2D/3D seismic data in area its neighboring,the mainly occurred late period Late Miocene ended Mio/ Pliocene boundary(5.5Ma) this paper.The affects Rise Chaoshan Depression.Besides,the eastern part Panyu Low-High southern northeastern Zhu Ⅰ Depression are also deformed.Its main deformation...
A new 3D seismic reflection data volume acquired in 2012 has allowed for the detailed mapping and characterization of gas hydrate distribution Pearl River Mouth Basin South China Sea. Previous studies core logging showed that occurrence at high concentrations is controlled by presence relatively coarse-grained sediment upward migration thermogenic from deeper section into overlying stability zone (BGHSZ); however, spatial remains poorly defined. We used a constrained sparse spike inversion...
Gas hydrate dissociation may pose serious geohazards. The response of the seafloor to is important for geohazards, marine environments and global climate. We studied how affects underground temperature pressure lead deformation. Here, we designed a laboratory model experiment visualize fluid migration deformation during at atmospheric pressure. Our experiments show visible gas pipes, migratory pockets due explain newly discovered discordance between slide plane base stability zone. found...
Abstract Fluid seepage sometimes impacts occurrences of submarine landslides, but the role landslide deposits in fluid is often neglected. Bathymetric data show that more than 1,000 seabed mounds are scattered over an elongated area at shelf edge northwestern South China Sea. Vertical seismic pipes subsurface spatially correlated with both surface and buried deposits. Detailed analyses within three‐dimensional (3D) survey least 221 231 (∼96%) have spatial correlation top edges multiple...
Polygonal faults were identified from three-dimensional (3D) seismic data in the middle-late Miocene marine sequences of South China Sea. study area are normal with fault lengths ranging 100 to 1500 m, spaces 40 800 and throws 10 m. Gas hydrate was inferred polarity, reflection strength, temperature-pressure equilibrium computation results. hydrates located sediments above polygonal layer. can act as pathways for migration fluid flow, which supply hydrocarbons formation gas hydrates.
Sedimentary organic matter (SOM) on continental slopes in marine regions can sensitively record climatic and environmental changes. In this study, total carbon content (TOC), nitrogen (TN), their stable isotope compositions (δ 13 C δ 15 N) for sediments of core G02 were investigated (at ∼24.2-year resolution) to reveal the temporal variations sources main controls distribution buried northwestern slope South China Sea over last ∼8600 years. Results a binary mixing model that ∼82.3 ± 3% SOM...
The South China Sea is the biggest marginal sea in West Pacific.The environmental conditions are favorable there to growth of reefs.The Dongsha uplift was a shallow water area far from provenance Miocene.The marine including temperature,salinity and depth were excellent for reef growth.Base on integrated study seismic,well logging core data,and taking into account relative level changes,we believe that plenty reefs developed different horizons area,due complicated cooperation change regional...
The types, influencing factors and their evolutions of focused fluid flow systems in the northern South China Sea (SCS) are deeply studied based on high-resolution 3D 2D seismic data. These include mud volcanoes, diapirs, gas chimneys, pipes, polygonal faults tectonic faults. They influenced by both tectonism sedimentation. diapirs volcanoes may have relationship unidirectional evolution we can separate them from whether sediments involved or fluids erupt into seawater not. Finally, a...
The complexity of carbonate deposition and diagenesis leads to the reservoir heterogeneity.The analysis intersections well logs in area Liuhua oil field on Dongsha massif suggest that velocity,density seismic acoustic impedance are most relevant physical parameters porosity.Based quantitative properties from 3d logging data,we summarized this paper heterogeneous characteristics reef platform,and described its properties,by using techniques inversion attributes analysis.The results show...
