Vermiculite
Vermiculite is a hydrated phyllosilicate mineral with the chemical formula Mg0.7(Mg,Fe,Al)6(Si,Al)8O20(OH)4 * 8H2O. It crystallizes in the monoclinic system and is characterized by its low hardness of 1.3 on the Mohs scale, a density of 2.55 g/cm³, and a pearly to vitreous luster. It typically appears in shades of brown, yellow, or green. Vermiculite is classified as a phyllosilicate in the Strunz system (9.EC.50) and as a member of the mica group in the Dana classification (71.2). Its flaky, flexible structure and high water content are key physical features.

Etymology
The name 'vermiculite' is derived from the Latin word 'vermiculari,' meaning 'to breed worms,' due to the worm-like appearance of the mineral when it expands upon heating.
Geological genesis
As a phyllosilicate, vermiculite typically forms through the weathering or hydrothermal alteration of other silicate minerals, particularly biotite or other micas, in low-temperature metamorphic or hydrothermal environments.
