| 摘 要： | 研究沿海地区全新世沉积特征与形成年代,进行地层划分与对比,恢复沉积环境及演变历史,对探讨海岸线变迁、海平面变化与地壳运动等理论问题,有重要意义。以往,海南岛沿岸全新世沉积与地层的研究比较薄弱,主要涉及珊瑚礁、沿岸砂堤等。

| Abstract: | Radiocarbon datings of several profiles of Holocene sediments have enabled us to subdivide and correlate these profiles in relation to sea-level changes. Preliminary conclusions are given as follows.1. Several index stratigraphic units have been established, i.e. the Luhuitou raised coral-reef, formed in the middle stage of the Middle Holocene (5200-4900 yrs. B. P.); the Luhuitou formation composed of coral sand, gravels and secondary reef was formed in the middle and late stages of the Middle Holocene (about 4300 yrs. and 3800-3600 yrs. B. P.), and the Yandun formation (marine sands and sand stones) and the Haikou formation (lagoona clayey sand and sandy clay) deposited in the early and middle stages of Late Holocene (2200-2000 yrs. and about 1600 yrs. B. P.) respectively.2. The middle-late Holocene beachrocks can be further divided into two kinds, the Luhuitou and the Yandun ones (about 3750 and 2000 yrs. B. P. respectively).3. Evidences for four higher sea-levels (dated 5200-4900, 4300,, 3800-3600 and 2100-1500 yrs. B. P. respectively) along the coast of Hainan Island are found in the Holocene. |
