  • 摘要: 天然气水合物作为全球碳循环中最大的碳储库,在全球变暖或海平面变化导致压力减小的情况下将分解释放大量甲烷进入水体和大气,对气候和环境造成巨大的影响。自从1995年Dickens等提出形成晚古新世温度峰值事件(LPTM)的主要原因是海底天然气水合物大规模分解释放甲烷这一假说以来,地质历史时期天然气水合物演化的研究蓬勃发展。而晚第四纪以来经历了一系列气候变化过程,在加利福尼亚的圣巴巴拉盆地、瓜伊马斯盆地、俄罗斯的贝加尔湖、格陵兰海、秘鲁、东格陵兰陆架、巴布亚新几内亚以及南海等地都记录了天然气水合物分解释放而形成的碳同位素负偏的古环境信息。主要针对这些古环境记录进行整理总结,为进一步研究天然气水合物的动态演化提供基础。
    Abstract: Gas hydrate serves as the largest reservoir in the global carbon cycle. It may release lots of methane into water column and atmosphere due to the global warming and/or sea level falling, which greatly affects climate and environment. Since Dickens et al. proposed the hypothesis that massive methane releasing from gas hydrate is one of the most important reasons of the Latest Paleocene Thermal Maximum (LPTM) in 1995, great research effort has been focused on the evolution of gas hydrate in geological history. A series of climate fluctuations have occurred since the late Quaternary, and scientists have found paleoenvironmental records of carbon isotope negative excursions in Santa Barbara basin, Guaymas basin, Lake Baikal, Greenland Sea, Peru, East Greenland continental shelf, Papua New Guinea, and South China Sea, which are related to the gas hydrate-derived methane. In this study, we compile these records to provide valuable information for future studies of dynamic evolution of gas hydrate.

摘要: 天然气水合物作为全球碳循环中最大的碳储库,在全球变暖或海平面变化导致压力减小的情况下将分解释放大量甲烷进入水体和大气,对气候和环境造成巨大的影响。自从1995年Dickens等提出形成晚古新世温度峰值事件(LPTM)的主要原因是海底天然气水合物大规模分解释放甲烷这一假说以来,地质历史时期天然气水合物演化的研究蓬勃发展。而晚第四纪以来经历了一系列气候变化过程,在加利福尼亚的圣巴巴拉盆地、瓜伊马斯盆地、俄罗斯的贝加尔湖、格陵兰海、秘鲁、东格陵兰陆架、巴布亚新几内亚以及南海等地都记录了天然气水合物分解释放而形成的碳同位素负偏的古环境信息。主要针对这些古环境记录进行整理总结,为进一步研究天然气水合物的动态演化提供基础。
