Mineral water is water from a mineral spring that contains various minerals, such as salts and sulfur compounds. It is usually still, but may be sparkling ( carbonated / effervescent ). Traditionally, mineral waters were used or consumed at their spring sources, often referred to as "taking the waters" or "taking the cure," at places such as ...
The methods of using fluid inclusions to identify mineral deposits include assessing the abundance of a specific inclusion type, looking into variations in the inclusions' temperatures of phase changes during heating and cooling, [2] and variations in other properties such as decrepitation behavior, and inclusions chemistry.

Mineral classification schemes and their definitions are evolving to match recent advances in mineral science. Recent changes have included the addition of an organic class, in both the new Dana and the Strunz classification schemes. [152] [153] The organic class includes a very rare group of minerals with hydrocarbons. The IMA Commission on ...
The mineral is uniaxial (-), with refractive indices n ω = 1.638 to 1.655 and n ε = 1.632 to 1.650. [ 4 ] [ 5 ] It is sometimes fluorescent , white to blue-white or yellow-white in short-wave ultraviolet light, and medium white-yellow-brown or weak white in long-wave light.
In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl.Further classification is done by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones.

The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal. It is chemically similar to columbite , and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.
Evian (/ ˈ eɪ v i ɒ n / AY-vee-on, [2] ev-ee-un; [3] French:, stylized as evian) is a French brand that bottles mineral water from several sources near Évian-les-Bains, on the south shore of Lake Geneva. [4] Today, Evian is owned by Danone, a French multinational corporation.
Grand Prismatic Spring and Midway Geyser Basin in Yellowstone National Park. A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth.
