摘要/Abstract

摘要：

珊瑚礁广泛发育于我国南海海域, 其生长记录中保存了海洋气候环境变化的各种信息, 是一种重要的环境记录载体。文章以南沙美济礁南科1 (NK-1)井为研究对象, 系统分析了珊瑚礁碳酸盐岩中的脂类生物标志物组成与分布特征, 重点探讨了短链正构C_14~18脂肪酸在重建古生产力方面的潜力及其环境指示意义。结果表明, 该类脂肪酸对成岩作用和降解改造具有高抗性, 与陆源营养输入、表层水体生产力、海平面变化密切相关, 可作为重建造礁珊瑚古生产力记录的可靠指标。此外, 在45~65m和95~110m层段识别出具有石油烃类特征的脂肪烃组合, 结合美济礁区域构造背景与年代学数据, 推断其为中—晚更新世自然烃类渗漏事件的产物, 可能由台湾岛斜向弧陆碰撞引发。该研究揭示了南海珊瑚礁区环境记录能力, 既能响应万年尺度的古生产力, 也能为突发性自然烃类渗漏事件提供新的地球化学证据。

Abstract:

Coral reefs have developed extensively in the South China Sea, and their growth records preserve diverse information on marine climate and environmental changes, making them a crucial environmental archive. This study focuses on the Well NK-1 site on Meiji Atoll, systematically analyzing the composition and distribution of lipid biomarkers within coral reef carbonate rocks, with emphasis on the potential of short- and medium-chain C_14-18 fatty acids for reconstructing paleoproductivity and their environmental implications. The results indicate that these fatty acids exhibit high resistance to diagenesis and degradation, and are closely correlated with terrestrial nutrient input, surface-water productivity, and sea-level changes, thus serving as reliable proxies for reconstructing the paleoproductivity records of reef-building corals. Furthermore, aliphatic hydrocarbon assemblages with petroleum hydrocarbon signatures were identified in the 45-65 m and 95-110 m stratigraphic intervals. Integrating the regional tectonic setting and chronological data of Meiji Reef, these assemblages are inferred to be products of natural hydrocarbon seepage events during the Middle-Late Pleistocene, potentially triggered by the oblique arc-continent collision in the Taiwan region of China. This study reveals the environmental recording capacity of coral reef areas in the South China Sea, showing that they can respond to paleoproductivity on a millennial scale, while also providing new geochemical evidence for abrupt natural hydrocarbon seepage events.

Key words: Meiji Atoll, biomarkers, productivity indicators, southern South China Sea
