Seep carbonates precipitated around the cold seep sites documented the information of the past methane-rich fluid flow at continental margins.In this paper,chimney-like seep carbonate samples from the northeastern Dongsha area of the South China Sea were collected and studied in detail to understand the origin and nature of the venting fluids and their potential relationship with gas hydrate deposits underneath the seafloor.

新特提斯海的关闭时间直接标志着特提斯洋的消失,喜马拉雅山脉隆升的起始.对于理解印度-亚洲大陆碰撞过程、喜马拉雅山脉的隆升及其导致的环境-气候变化具有重要的意义.新特提斯海的关闭时间(通常通过研究海相地层的消失、最早陆相地层的出现来获得)长期以来存在很大的不确定性.这直接导致科学界对印度-亚洲大陆碰撞(定义为新特提斯洋壳的消失)初始时间的巨大争论.

二叠纪发生了两次生物大灭绝事件,其中发生于二叠纪末期的(～252.2 Ma)为显生宙规模最大的一次,另一次发生于瓜德鲁普世末期(～260 Ma).高精度的年代地层格架对于理解二叠纪生物大灭绝事件和其后复苏过程的物理、环境、生态、化学变化过程,以及触发机制都极为关键.近年来,华南瓜德鲁普世—中三叠世的生物地层学、化学地层学、磁性地层学和高精度放射性年代学方面均取得了重要进展,但仍然无法在所有重要剖面
Hydrate Ridge is a bathymetric high on the Oregon margin,off Newport,where gas hydrates have been widely studied in the past decades.Near the summit of the ridge,a large carbonate structure referred t
It has been widely reported that natural gas hydrate systems are often associated with the presence of cold seeps,seafloor vents or other manifestations of free gas co-existing within the thermodynami
Wireline logging data acquired during Chinas first gas hydrate drilling expedition (GMGS-1) in April-June of 2007 and seismic data indicate the occurrences of gas hydrate above the base of gas hydrate
The detailed thermal regime in marine gas hydrate bearing formation has not been accurately known in Nankai Trough yet.There was a previous work of temperature measurement over gas hydrate bearing for
We have performed a survey of hydrates and associated oil seepage first discovered with acoustic observations of massive gas plumes 20miles offshore California in the Eel River Basin.
Chinas researchers confirmed the Natural Gas Hydrate in the Tibetan Plateau and the South China Sea.It is important to research the mechanical behavior of hydrate bearing sediment in-situ conditions.T
Geophysical remote quantification of seafloor methane hydrates is needed for studies of the impact of global warming on greenhouse gas release into the water column and atmosphere,for geohazard predic
