Chemical properties. The idealized chemical formula of chrysotile is Mg 3 (Si 2 O 5) 4, although some of the magnesium ions may be replaced by iron or other cations.
The chemical reaction turns olivine into serpentine minerals. They may also have their origins in metamorphic alterations of peridotite and pyroxene. Serpentines may also pseudomorphously replace other magnesium silicates. Incomplete alteration causes the physical properties of serpentines to vary widely.
Lizardite, chrysotile, and antigorite all have approximately the formula Mg 3 (Si 2 O 5)(OH) 4 or (Mg 2+, Fe 2+) 3 Si 2 O 5 (OH) 4, but differ in minor components and in form. [10] Accessory minerals, present in small quantities, include awaruite, other native metal minerals, and sulfide minerals. [12] Ophiolite of the Gros Morne National Park ...
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.
More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic rocks. The term "serpentine" is commonly used to refer to both the soil type and the mineral group which forms its parent materials.

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]
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.
