Chlorites with a muscovite-like silicate layer and an aluminum hydroxide sheet are called donbassite and have the ideal formula of Al4.33(Si3Al)O10(OH)8 as an end-member for the dioctahedral chlorite. Often occurring as an alteration product of biotite mica or chlorite in the near-surface zone of weathering, vermiculite is typically found associated with ultramafic rock types such as peridotite and pyroxenite that have been previously altered by intrusions of granite, pegmatite, or alkalic rocks. Chlorite structures are relatively thermally stable compared to kaolinite, vermiculite, and smectite minerals and are thus resistant to high temperatures. (Figure 5). Expanded vermiculite is widely used in the shipping industry as a packing material. The EPA Responds. Clay mineral vermiculite (VER) was used as the clay mineral nanofiller into polymer matrix and was intercalated with the maleic anhydride into polyamide , polyethylene , and polypropylene [89, 111].

As a hydrous mica-like mineral, vermiculite expands rapidly when heated to temperatures >900 C. The contained water converts to steam forcing individual mineral laminae apart, a process known as exfoliation. Because of its effectiveness as an absorbent, it is commonly used when shipping hazardous materials.
