Gas hydrates: a primer

THE .pdf ISN'T DISPLAYING ON FIGSHARE'S PREVIEW FOR REASONS UNKNOWN. TRYING TO FIX... This graphic is a draft from an educational course I'm compiling about the Earth's natural gas reserves. It attempts to summarise what gas hydrates are and where they can be found, adn accompanies further graphics that explain the chemistry of hydrates. No attempt is made to quantify the amount of methane that might be present in these deposits globally - this is the subject of much uncertainty. Those interested in the details of resource size can refer to the sources listed in the graphic and GEA (2012). <em>Global Energy Assessment - Toward a Sustainable Future</em>. Cambridge University Press. I hope some will find this useful. Any comments, corrections and queries welcome.

因不明原因，该PDF无法在FigsShare的预览界面中正常显示，目前我们正在尝试修复该问题。本图示为笔者正在编制的一门关于地球天然气储量的教育课程的草稿，旨在简要阐释天然气水合物（gas hydrates）的定义及其赋存环境，并配套后续用于讲解水合物化学特性的相关图示。本图未对全球此类沉积物中可能蕴藏的甲烷（methane）储量进行量化——这一议题尚存诸多不确定性。希望了解资源规模具体细节的受众，可参考图示中列出的资料来源以及GEA（2012）：《全球能源评估：迈向可持续未来》（Global Energy Assessment - Toward a Sustainable Future），由剑桥大学出版社出版。希望本材料能对部分受众有所助益，欢迎各位提出意见、修正建议与疑问。
