Summary
[edit]DescriptionRock salt (halitite) (Billianwala Salt Member, Salt Range Formation, Ediacaran to Lower Cambrian; Khewra Salt Mine, Salt Range, Pakistan) 11 (33275221442).jpg |
English: Rock salt (halitite) from the Precambrian-Cambrian of Pakistan.
This rock is halitite, also called rock salt. As its name suggests, it is entirely composed of halite (NaCl - sodium chloride). Halitite is the most common type of evaporite, a crystalline-textured, chemical sedimentary rock formed by the evaporation of water (usually seawater), and the precipitation of dissolved minerals. Most halitites are clear to whitish to grayish. This sample is from Pakistan's Khewra Salt Mine, one of the most significant salt mines on Earth. Rock salt specimens from this site are usually clearish-whitish to pinkish-orangish. Stratigraphy: Billianwala Salt Member, lower Salt Range Formation, Ediacaran to Lower Cambrian Locality: Khewra Salt Mine, southern flanks of the eastern Salt Range, northeastern Pakistan (mine adit at 32° 38' 52.68" North latitude, 73° 00' 30.24" East longitude) See geologic info at: http://paleopolis.rediris.es/cg/CG2009_BOOK_03/CG2009_BOOK_03_Chapter06.pdf |
