2. Diopside - Wikipedia

   en.wikipedia.org/wiki/Diopside

   A green diopside found in Outokumpu, Finland. Diopside is a precursor of chrysotile (white asbestos) by hydrothermal alteration and magmatic differentiation; [6] it can react with hydrous solutions of magnesium and chlorine to yield chrysotile by heating at 600 °C for three days. [7]

3. Serpentinization - Wikipedia

   en.wikipedia.org/wiki/Serpentinization

   Lizardite and chrysotile are stable at low temperatures and pressures, while antigorite is stable at higher temperatures and pressure. [31] Its presence in a serpentinite indicates either that serpentinization took place at unusually high pressure and temperature or that the rock experienced higher grade metamorphism after serpentinization was ...

4. Chrysotile - Wikipedia

   en.wikipedia.org/wiki/Chrysotile

   Chrysotile or white asbestos is the most commonly encountered form of asbestos, [5] accounting for approximately 95% of the asbestos in the United States [6] ...

5. Serpentine subgroup - Wikipedia

   en.wikipedia.org/wiki/Serpentine_subgroup

   Serpentines find use in industry for several purposes, such as railway ballasts, building materials, and the asbestiform types find use as thermal and electrical insulation (chrysotile asbestos). The asbestos content can be released into the air when serpentine is excavated and if it is used as a road surface, forming a long-term health hazard ...

6. Tremolite - Wikipedia

   en.wikipedia.org/wiki/Tremolite

   Tremolite is an indicator of metamorphic grade since at high temperatures it converts to diopside. Tremolite occurs as a result of contact metamorphism of calcium and magnesium rich siliceous sedimentary rocks and in greenschist facies metamorphic rocks derived from ultramafic or magnesium carbonate bearing rocks.

7. List of minerals - Wikipedia

   en.wikipedia.org/wiki/List_of_minerals

   Parachrysotile (a polytype of chrysotile) Pelagosite (variety of aragonite) Pericline (variety of albite) Peridot (gem-quality olivine) Perlite (volcanic glass) Phengite (variety of muscovite) Phosphorite (name given to impure, massive apatite.) Pimelite; Pitchblende (a massive impure form of uraninite) Plessite (mixture of kamacite and taenite)

8. Asbestiform - Wikipedia

   en.wikipedia.org/wiki/Asbestiform

   The most common asbestiform mineral is chrysotile, commonly called "white asbestos", a magnesium phyllosilicate part of the serpentine group. Other asbestiform minerals include riebeckite, an amphibole whose fibrous form is known as crocidolite or "blue asbestos", and brown asbestos, a cummingtonite-grunerite solid solution series.

9. Peridotite - Wikipedia

   en.wikipedia.org/wiki/Peridotite

   Peridotite that has been hydrated at low temperatures is the protolith for serpentinite, which may include chrysotile asbestos (a form of serpentine) [43] and talc. [67] Layered intrusions with cumulate peridotite are typically associated with sulfide or chromite ores.
