摘要: High-resolution seismic reflection data recorded on the continental slope off east coast of United States have revealed instances sediment mass movement (slumps) which appear to occur above clathrate accumulations. The slumping is believed be related liberation free gas by decomposition and consequent weakening unconsolidated sediments clathrate. Pleistocene sea-level lowering and/or post-Pleistocene bottom water temperature increases may had a significant role in this process.
