• also called sheet silicates
• group of minerals that includes the micas, chloride, serpentine, talc and clay minerals.

• phyllosilicates

• biotile

• chlorite

• andisols

• also called soapstone; has the formula Mg3Si4O10(OH)2
• found in low grade metamorphic rocks that originated as ultra basic to basic igneous rocks rocks composed almost entirely of talc have a greasy feel

• talc

• mica group

• chlorite group

• common constituent of Al-rich medium grade metamorphic rocks.
• also found in silicons, Al-richplutonic igneous rocks (metamorphic granites) but has not been found as a constituent of volcanic rocks.

• muscovite

• biotile

• chlorite

• andisols

• found in hydrons ultrabasic rock like kimberlite
• common trachytic volcanic rocks, granitic, plutonic rock and a wide variety of metamorphic rocks.
