- Type
- Coal deposit (semianthracite, Cretaceous)
Semianthracite seam of Cretaceous age; sample PSOC 159 of the DOE Coal Sample Bank (Pennsylvania State University), homogenised and packed under argon; mercury with a mean δ202Hg of -2.76 ‰ and Δ201Hg of +0.03 ‰ (Biswas et al., 2008). Weathered seam whose name is unknown to the sample bank. Coordinates not given.
