摘要：
According to the tectonic movement occurring in the South China Sea since the late Miocene and the sea level changes in Yingqiong Basin, Pearl River Mouth Basin, and global, combining with seismic reflection terminate characteristics, we divided Shenhu gas hydrate survey area's Pliocene strata into four sequences. According to the basic principles of the "outside- shape, internal-structure",from seismic wave external geometry, supplemented by seismic physical attributes (amplitude, frequency, consistence),we identified the fill, mound, sheet, lens, sheet shape, wedge-shaped 6 categories, a total of 19 kinds of seismic facies in the study area. Contrasting to the drilling gas hydrate depth, the gas hydrate is mainly enriched around the slump deposits.
