U11A:
Shale Across All Scales

Note: Abstract submissions to Union sessions are by invitation only.



Session ID#: 26373

Session Description:
Shale constitutes 25% of the earth's surface and hosts strategic elements, minerals, and energy resources at depth, and has been proposed as a possible host rock for geological storage of nuclear waste. Studying shale is difficult, however, because of its small particle and pore sizes and complexity of structure. In this session we will highlight presentations that elucidate the chemistry, structure and hydrology of shale with an eye toward its reactivity, transport properties, and its importance in the global economy, spanning environments from the deep subsurface to the critical zone. Speakers will emphasize new studies on the chemistry and structure of shale, anomalous transport and reactivity in shales, how shale is formed and why it hosts strategic natural gas resources, and new techniques of energy extraction.
