Ulexite (TV Stone): The mineral Ulexite information and pictures
http://www.minsocam.org/ammin/AM25/AM25_754.pdf Ulexite is found in evaporite deposits and the precipitated ulexite commonly forms a "cotton ball" tuft of acicular crystals. Ulexite is frequently found associated with colemanite, borax, meyerhofferite, hydroboracite, probertite, glauberite, trona, mirabilite, calcite, gypsum and halite. See more Ulexite (NaCaB5O6(OH)6·5H2O, hydrated sodium calcium borate hydroxide), sometimes known as TV rock or Television stone, is a mineral occurring in silky white rounded crystalline masses or in parallel fibers. The … See more Borate minerals are rare because their main component, boron, makes up less than 10 ppm (10 mg/kg) of Earth's crust. Because boron is a trace element, the majority of borate minerals occur only in one specific geologic environment: geologically active See more In 1956, John Marmon observed that fibrous aggregates of ulexite project an image of an object on the opposite surface of the mineral. This optical property is common for … See more Boron is a trace element within the lithosphere that has an average concentration of 10 ppm, although large areas of the world are boron deficient. Boron is never … See more Ulexite is a borate mineral because its formula (NaCaB5O6(OH)6·5H2O) contains boron and oxygen. The isolated borate See more Ulexite commonly forms small, rounded masses resembling cotton balls. Crystals are rare but will form fibrous, elongated crystals either oriented parallel or radial to each other. Crystals may also be acicular, resembling needles (Anthony et al., 2005). The point group of … See more Ulexite crystals contain three structural groups, isolated pentaborate polyanions, calcium coordinated polyhedra, and sodium coordinated octahedra that are joined together and … See more reddit college textbooks
