Geology:洋中脊產(chǎn)生的非生物甲烷是形成北極天然氣水合物儲(chǔ)層的重要來源

【摘要】：正最新出版的2015年第5期Geology雜志發(fā)表的有關(guān)天然氣水合物來源的研究成果指出,來自超慢速擴(kuò)張洋中脊的非生物甲烷是形成北極天然氣水合物儲(chǔ)層的重要來源。作為溫室氣體主要來源,甲烷通常由有機(jī)質(zhì)經(jīng)過細(xì)菌和微生物的復(fù)雜的分解過程所產(chǎn)生。但還有另一種類型的甲烷可以在特定條件下生成:非生物來源甲烷由海底洋殼的化學(xué)反應(yīng)形成。根據(jù)之前的研究,北極 【關(guān)鍵詞】： Geology;洋中脊;天然氣水合物;慢速擴(kuò)張;非生物;洋殼;研究成果;地球物理數(shù)據(jù);構(gòu)造環(huán)境;拉姆;
