Datolite is a Calcium Boron Hydroxide Nesosilicate.
Derivation of Name
Jens Esmark was the first to study it in 1806, who gave it its name δατεῖσθαι, "to divide," and λίθος, "stone," referring to the granular structure of the huge mineral.
Related minerals are Babingtonite, Danburite, Epidote, Prehnite, Calcite, Native Copper, Quartz and Zeolites. It appears as a secondary mineral in mafic igneous rocks, frequently filling vesicles along with zeolites in basalt. Unlike most regions all over the world, the Datolite found in the Lake Superior region, regularly has a fine grained texture with colored banding. Much of coloration is because of the inclusion of copper or connected minerals in progressive stages of hydrothermal precipitation.
Most collectors go for Datolite for their gem collection. Minor gemstones and ornamental stones are cut and polished from nodules in Michigan. In Russia, they mine Datolite to source Boron.. It helps problem-solving and enhancing our memory, particularly the ability to memorize important things. This crystal helps people to become more affectionate. This crystal also pulls us closer physically to people we love.
The regions where this mineral occurs are in the diabasis of the River Valley of Connecticut as well as Arendral, Aust-Agder in Norway. Prominently they also occur in the Lake Superior region of Michigan, New Jersey and Paterson in USA; Russia; Ontario, Bancroft, Canada; Schwarzwald, Germany, Norway and Charcas, Mexico.
The mineral Datolite is an admired mineral among mineral collectors, though it is somewhat difficult to understand. It forms complex crystals with agreeable facetes. At first sight the crystals could appear to be some other crystal forms like the isometric Dodecahedron or Trapezohedron that have very symmetric crystal forms, which, without doubt are distinguishable from those of Datolite. Datolite's crystals, though generally well formed and strikingly faceted, lack symmetry elements except for one mirror plane and one axis of two fold rotation.
Color is white, colorless, gray, yellowish, reddish, brown and green.
