【摘要】 根据多道地震反射资料分析,在冲绳海槽南部和中部发现了拟海底反射层(BSR)现象。通过对海底异常反射层的振幅特征、速度异常和AVO属性分析,说明该BSR可能反映了天然气水合物的存在,并发现冲绳海槽断层与天然气水合物的形成有密切关系。更多还原

【Abstract】 According to the analysis of multichannel seismic reflection data, the BSRs are found in the southern and central areas of Okinawa Trough. The analyses of seismic attributions of amplitude, velocity and AVO explain that the BSRs are generated by the gas hydrate. And it is found that gas hydrate is closely related to fault in the Okinawa Trough.更多还原
