在包括西伯利亚、马更些三角洲、阿拉斯加北部斜坡在内的北极地区都已查明有大量的正在形成中的气水合物。在阿拉斯加北部斜坡,甲烷水合物稳定带延伸到了沿海的平原地区,而且在普拉德霍湾地区厚度超过1000m,该斜坡的大部分气水合物是在六个连续的第三系的砂岩和砾岩中发现的。在北部斜坡,包含在气水合物中的天然气体积估计大约在1.0×10~(12)~1.2×10~(12)m~3之间;地球化学分析表明已经发现的水合物中的气体可能是深部热成因气和浅源微生物成因气的混合物。
A large number of emerging gas hydrates have been identified in the Arctic, including in Siberia, the Mavero Delta and the northern slope of Alaska. On the northern slope of Alaska, the methane hydrate stability zone extends to the coastal plains and is more than 1000 m thick in the Prudhoe Bay, where most of the gas hydrate is formed in six consecutive Tertiary sandstone and gravel Found in rocks. On the northern slope, the volume of natural gas contained in the gas hydrate is estimated to be approximately between 1.0 × 10 12 and 1.2 × 10 12 m 3; the geochemical analysis shows that the gas in the hydrate that has been found may be It is a mixture of deep pyrogenetic gas and gas of shallow microbial origin.
