Mud diapirs and gas chimneys are widely developed in continental slope areas, which can provide sufficient for hydrate formation, they important finding natural hydrates. Based on the interpretation analysis of high-resolution 2D 3D seismic data covering deep-water area Qiongdongnan Basin (QDNB), northern South China Sea, we studied formation mechanism mud their relationship with columnar domelike shape internal regions these bodies have abnormal reflections characterized by fuzzy, chaotic,...
The mechanism of slope failure associated with overpressure that is caused by hydrocarbon migration and accumulation remains unclear. High-resolution seismic data gas hydrate drilling collected from the Shenhu field (site SH5) offer a valuable opportunity to study relations between submarine flow ∼2 km-diameter chimney developed beneath site SH5 where none hydrates had been recovered sampling despite presence distinct bottom simulating reflectors (BSRs) favorable indication. resulted...
Submarine cold seeps have recently attracted significant attention and are among the most effective indicators of gas hydrate in oceans. In this study, remotely operated vehicle (ROV) observations, seismic profiles, core sediments, bottom seawater, fluid vented from deep-water Qiongdongnan Basin were used to investigate origin evolution their relationships with hydrate. At stations A, B, C, inactive dead clams, seep leakage live active a rich mussel presence, respectively, observed. The...
Studying deep-water cold seep systems is of great significance to gas hydrate exploration due their close relationship. Various and related accumulations have been discovered in the northern South China Sea past three decades. Based on high-resolution seismic data, subbottom profiles, situ submergence observations, deep drilling coring, geochemical analyses, geological geophysical characteristics these associated Qiongdongnan Basin, Shenhu area, Dongsha Taixinan Basin investigated. Cold are...
Abstract The subduction of the Bangonghu‐Nujiang Meso‐Tethys and collision between Lhasa Qiangtang blocks were important events in growth Tibetan crust. However, timing initiation closure timing, as well nature structure Bangonghu ocean basin, are still poorly constrained. Lagkor Tso ophiolite, located south Gerze County, Tibet, is one most completed ophiolites preserved southern side suture zone. This study discussed tectonic evolution zone revealed by ophiolite investigated field...
Cold seep, characterized by active material circulation and methane seepage, is of great importance to reconstruct the paleo-marine environment trace origin life occurrence minerals. Southern South China Sea (SCS) with ample oil gas resources an ideal platform for cold seep study, but information researches on seeps here are rather deficient. We studied geochemical characteristics sediment cores pore water combined seismic profile in Beikang Basin, aiming further understand nature this area....
During the Mesozoic, Southeast (SE) Asia (including South China and Sea (SCS)) was located in a transitional area between Tethyan Pacific geotectonic regimes. However, it is unclear whether geodynamic processes SE Asian continental margin were controlled by or paleo-Pacific Ocean subduction. Herein, we report ~124 Ma adakitic granodiorites Nb-enriched basalts from Xiaozhenzhu Seamount of SCS. Granodiorites have relatively high Sr/Y (34.7–37.0) (La/Yb)N (13.8–15.7) ratios, as well low Y...
Mud volcanoes are important to understand hydrocarbon research and exploration, crustal movement neotectonic activity, geological engineering, climate change. They widely distributed along the Alps‐Tethys suture zone, Pacific belt, continental slopes. Previous detailed studies on mud concentrated mostly onshore areas. Recent developments in geophysical technology have opened vast deepwater areas for volcanoes. Based multibeam bathymetry, multichannel seismic reflection, gravity, magnetics...
Abstract Mud volcanoes have provided much meaningful information about the deep Earth and recent crustal neotectonic movements in an area for over 200 years. However, triggering mechanisms puzzled geologists a long time. This study investigated factors controlling mud volcano activity of eruptions on southern margin Junggar Basin, NW China. The Baiyanggou, Aiqigou Dushanzi are all located along Anticline, which belongs to third anticline belt basin. extensive, thick mudstone at depth...
Mud volcanoes and other fluid seepage pathways usually transport sufficient gas for the formation of reservoirs are beneficial to accumulation hydrate. On hand, thermal effects mud can constrain occurrence hydrates. Current field measurements indicate that anomalies impact distribution hydrates associated with volcanoes. However, due lack quantitative analysis volcano flow evolution, it is difficult effectively reveal in development areas estimate their resource potential. This study took...
Mud volcanoes can provide important information about the underlying strata, hydrocarbon accumulation, and recent neotectonic movements in an area. The fluids erupting from mud their formation evolution. ion concentration hydrogen oxygen isotopes of that were erupted three volcano groups, Baiyanggou, Aiqigou, Dushanzi, nearby rivers southern margin Junggar basin, northwestern China, are studied. concentrations Na Cl clearly elevated, displayed as Na-Cl type. δD δ18O values similar between...
Oil spills interact with mineral particles to form oil–particle aggregates (OPAs), which promotes the oil's natural diffusion and biodegradation. We investigated effect of bacteria on formation vertical migration OPAs under different concentrations types proposed elucidated an oil–particle–bacteria coupling mechanism. The depth particle penetration into oil droplets (13–17 μm) was more than twice that nonbacterial group. remained in water column deposited bottom decreased from 87% 49%...
