Bioherm developmental mode in deepwater area of Qiongdongnan Basin

摘要

摘要: 通过对琼东南盆地深水区古构造、古地理及海平面变化条件分析，认为琼东南盆地深水区中新统具备良好的生物礁形成条件。从层序地层结构特征分析认为，琼东南盆地深水区南部发育断控台缘和缓坡台缘2种台缘结构生物礁发育模式，且2种发育模式的生物礁在成礁演化上差异明显。其中，断控型台缘结构发育模式梅山组二段沉积期为主要的成滩期，梅山组一段沉积期为主要的成礁期；而缓坡型台缘结构发育模式梅山组二段沉积期存在成滩期和成礁期，但生物礁发育规模较小，梅山组一段沉积期则主要为成礁期。

Abstract: The analyses of paleostructure, paleogeographic and sea level changes in the deepwater area of the Qiongdongnan Basin show that Miocene is favorable for bioherm development. The characteristics of sequence stratigraphic structure indicate that both slope platform margin and fault-controlled platform margin generate in the south of the deepwater area, giving birth to bioherm with obviously different evolution features. As to the fault-controlled platform margin, the Mei2 period is the main beach-forming period, and the Mei1 period is the main bioherm-forming period. As to the slope platform margin, both beach and bioherm develop during the Mei2 period, and the bioherm development scale is smaller; while in the Mei1 period, only beach develops.
