Halite salt casts in the Mississippian of West Virginia, USA. One of the most distinctive and environmentally diagnostic features in the sedimentary record is a halite salt cast. Halite (NaCl - sodium chloride) is a relatively common mineral - it is abundantly preserved in ancient evaporite successions and modern evaporite settings. If seawater-soaked siliciclastic sediments dry out, halite crystals may form. Halite crystals will almost always have nice cubic forms, but they can have embayed faces. This mineral is readily soluble in water, so halite may precipitate and redissolve relatively quickly. The crystal forms may become preserved in the sediments, as casts. Preserved halite salt casts unquestionably demonstrate that the sedimentary environment was an evaporite setting. Halite salt casts are rare - I've only seen them at three localities in the field. The examples shown above are in a mudshale outcrop. Stratigraphy: Hinton Formation or upper Bluefield Formation, Upper Mississippian Locality: roadcut through Divide Ridge on the northern side of Rt. 460, between Oakvale and Kellysville, southeastern Mercer County, far-southern West Virginia, USA (37º 20' 41.53" North latitude, 80º 56' 16.71" West longitude) |
