The Tectonic Evolution and Sequence Stratigraphy of Passive Continental Margins DeepWater Basin

Key words: 
• passive continental margins deepwater basin

Abstract: Deepwater oil and gas exploration is the most potential area of the worldwide oil and gas exploration, and the tectonic evolution and stratigraphy sequence researches of Passive Continental Margins Deepwater basin have important theory and practice significance. After the integrated researches of typical Passive Continental Margins Deepwater basin, it has been pointed out that Passive Continental Margins Deepwater basin experienced four regional tectonic evolution stages (continental rift onset, continental break up, early continental margins and mature continental margins), and developed three unconformities (Rift onset unconformity, Breakup unconformity and Continental Rise transform unconformity). In addition, it can be identified four tectonosequences (continental rift onset sequence, continental break up sequence, early continental margins sequence and mature continental margins sequence) in these basins.
