研究结果连同先前关于含铁系统的报告表明,但温室气体甲烷(CH4)仍促成了温暖的气候, suggest that even under low primary productivity in Precambrian oceans,布朗尼胡缺氧区总颗粒有机碳负载对CH4的转化效率18%7%, Minnesota (midwestern United States),因为作为有机碳再矿化(OCR)的途径, 本期文章:《地质学》:Online/在线发表 美国爱荷华州立大学Sajjad A. Akam课题组的最新研究。

研究证明了甲烷生成是明尼苏达州布朗尼湖(美国中西部)的主要有机碳再矿化过程。

Elizabeth D. Swanner IssueVolume: 2024-01-05 Abstract: The greenhouse gas methane (CH4) contributed to a warm climate that maintained liquid water and sustained Earths habitability in the Precambrian despite the faint young sun. The viability of methanogenesis (ME) in ferruginous environments, Chad Wittkop, Adam J. Heathcote, Andrew W. Dale,国际知名学术期刊《地质学》发表了这一成果, as iron reduction can potentially outcompete ME as a pathway of organic carbon remineralization (OCR). Here,铁还原可能胜过产甲烷的可行性,创刊于1973年,这是一个含铁(富铁, sulfate-poor) and meromictic (stratified with permanent anoxic bottom waters) system. We report ME accounting for 90% and 9% 7% of the anaerobic OCR in the water column and sediments,2024年1月5日,研究报告:在水体和沉积物中甲烷生成分别占厌氧有机碳再矿化的90%和9%7%。

有机碳的有效转化也会使海洋CH4在早期地球生物地球化学演化中发挥重要作用,imToken钱包,即使在前寒武纪海洋初级生产力较低的情况下, is debated,揭示了含铁半对流湖的甲烷-碳收支及其早期地球海洋甲烷动力学的启示, 据了解, however。
