Tremolite forms a series with actinolite and ferro-actinolite. Pure magnesium tremolite is creamy white, but the color grades to dark green with increasing iron content. It has a hardness on Mohs scale of 5 to 6. Nephrite, one of the two minerals known as the gemstone jade, is a green crystalline variety of tremolite.
If XCO 2 is above 0.5, the metamorphic reactions favor formation of talc, magnesite (magnesium carbonate), and tremolite amphibole. These are classed as talc-carbonation reactions. Below XCO 2 of 0.5, metamorphic reactions in the presence of water favor production of serpentinite.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
Nephrite is a variety of the calcium, magnesium, and iron-rich amphibole minerals tremolite or actinolite (aggregates of which also make up one form of asbestos). The chemical formula for nephrite is Ca 2 (Mg, Fe) 5 Si 8 O 22 (OH) 2. [1] It is one of two different mineral species called jade.

Tremolite was discovered in 1789. [2] Hexagonite, a varietal form of tremolite, has a Mohs hardness of 5.0-6.0. [3] Like tremolite, it is a calcium magnesium silicate hydroxide with the formula: Ca 2 Mg 5 (Si 8 O 22) 2. [3] The mineral was given the name, hexagonite, because its crystal structure was believed at one time to be hexagonal.
This study found that a high percentage of people with type 2 diabetes tend to be deficient in three micronutrients: vitamins D and B12 and magnesium. These are also commonly deficient nutrients ...
