Crittenden eclipse development12/28/2022 The Fe precipitates were identified as schwertmannite at all locations, regardless of facies. The sediments were composed entirely of Fe precipitates and cemented organic matter. Depositional facies were defined as pools, terraces, or microterracettes based on cm-scale sediment morphology, irrespective of the distance downstream from the spring. Aqueous chemistry, mineral precipitates, microbial communities, and laboratory-based Fe(II) oxidation rates for this site were analyzed in the context of a depositional facies model. Check out trail sites, restaurants, and plenty of places to try oysters within the James River watershed.Lower Red Eyes is an acid mine drainage site in Pennsylvania where low-pH Fe(II) oxidation has created a large, terraced iron mound downstream of an anoxic, acidic, metal-rich spring. If the thought of oyster shucking makes you clam-up, you can get your oyster fix via the Virginia Oyster Trail.
