| Description |
English: Large block of chickenwire rock gypsum of the Eagle Valley Evaporite, a Pennsylvanian unit dominated by rock salt (halite, NaCl), rock gypsum (CaSO4·2H2O), and rock anhydrite (CaSO4). These three rock types formed by evaporation of seawater and the precipitation of dissolved minerals. With deep burial, evaporites tend to engage in upward, solid-state flow. A large area around Gypsum, Colorado is extensively deformed by dissolution and upward movement of various evaporite rocks - this is the Eagle Collapse Center, which covers about 2,500 square kilometers. Evaporite rock movement and deformation occurred principally in the late Cenozoic.
Locality: large block alongside 51 Road just north of the town of Gypsum, western Eagle County, northwest-central Colorado, USA Info. synthesized from: Chronic & Williams (2002) - Roadside Geology of Colorado. Lidke et al. (2002) - Geological Society of America Abstracts with Programs 34(6): 288. |
