Li, Long, Wei, Siwen, Lollar, Barbara Sherwood, Wing, Boswell, Bui, Thi H., Ono, Shuhei, Lau Vetter, Maggie C. Y., Onstott, Tullis C., Kieft, Thomas L., Borgonie, Gaetan, Linage-Alvarez, Borja, Kuloyo, Olukayode, van Heerden, Esta
Dissolved sulfate is a crucial electron acceptor for the subsurface biosphere, particularly for the living microbial ecosystems in the long-isolated (on the order of millions to billions of years) deep subsurface fracture waters in Precambrian cratons, e.g., in the Witwatersrand Basin of the...

N2 in deep subsurface fracture fluids of the Canadian Shield: Source and possible recycling processes
Download2021-12-20
Li, Long, Li, Kan, Giunta, Thomas, Warr, Oliver, Labidi, Jabrane, Lollar, Barbara Sherwood
In addition to high concentrations of CH4 and H2, abundant dissolved N2 is found in subsurface fracture fluids in Precambrian cratons around the world. These fracture fluids have hydrogeological isolation times on order of thousands to millions and even billions of years. Assessing the sources...
