Hydrothermal plumes are widely distributed throughout the global spreading ridges,yet few of them are microbiologically explored.
极地冰下无光、低温、寡营养的环境被认为是有产甲烷活性的生境,产生和释放的温室气体甲烷对于全球气候和碳通量的影响是巨大的.目前已经有关于极地冰川下产甲烷菌多样性的报道,但是由于在极地取样和培养方面的困难使得对于此处产甲烷活性的研究仍有欠缺,尤其是在特定环境条件下的活性研究更少.本研究尝试结合体外模拟培养和分子生物学技术研究东南极冰川下产甲烷菌活性和群落结构对温度和底物的响应.
Anaerobic oxidation of methane (AOM) at cold seeps often leads to formation of authigenic carbonates close to the seafloor.The AOM is conjointly operated by consortia of anaerobic methane-oxidizing ar
非对称的地壳增生广泛存在于全球洋中脊系统.在快速或者慢速扩张的洋中脊的中央段,强岩浆活动往往造成对称的海底地形和洋壳厚度.然而在慢速扩张洋中脊,构造活动经常致使转换断层的"内角"区域的海底隆升以及地壳减薄.我们研究了北冰洋Mohns 洋中脊从30 Ma 以来的演化历史,发现其岩浆供应量与地壳的构造作用经历了三个演化阶段.第一阶段:从30 Ma 开始,Mohns 洋中脊与冰岛热点逐步靠近,冰岛热点导
断层发震过程中,摩擦阻力决定了断层失稳条件,并控制着滑动速率和最终滑移量.因此,摩擦系数是研究断层发震机制的基础参数.而同震温度响应导致的温度异常,可在震后钻孔测温中获得并识别,为摩擦特性和发震机制等基础研究提供了非常独特的思路和有效手段.
Merwinite (Ca3MgSi2O8) was synthesized at 1.2 GPa and 1273K for 24 hours using a piston-cylinder apparatus.Its thermal elastic behavior was investigated from room T to 1273K with powder X-ray diffract
Ambient noise correlation method has been widely used to extract surface waves and tomography.The extraction of body waves has been very limited,but recent reports have suggested promises for deep inc
