鹿回头珊瑚岸礁是海南岛岸礁发育较好的地区之一,属于上升礁范畴。礁区沉积分为岸礁沉积和生物碎屑沉积两类。鹿区可划分为五个沉积相带:礁前带、礁沐生专带、礁坪带、海岸带和礁后泻湖带.各带按沉积特征还可细分为2—3个亚带。研究证明:沉积物粒度资料、物质组分和生物(特别是微体生物)的生态条件等可用作指相标志。
Luhuitou Coral Shore Reefs are one of the better developed coastal reefs in Hainan Island and belong to the category of rising reefs. Reef sediments are divided into two types of sediment deposition and biological debris. The deer area can be divided into five sedimentary facies: pre-reef, reef-muse, reef, coastal and post-Lagoon lacustrine lakes. Each belt can be subdivided into 2-3 sub-zones according to sedimentary characteristics. Research shows that sediment grain size data, material composition and biological (especially micro-organisms) ecological conditions can be used as a sign of phase.
