WebNotes: The number of cleavage planes can differ from mineral to mineral. Mica (e.g. biotite, chlorite or muscovite) has one cleavage plane, feldspar (e.g. orthoclase or plagioclase) has two which intersect at 90°, and amphibole (e.g. hornblende) has two which do not intersect at 90°. Calcite has three cleavage planes which do not intersect at ... Web1 Biotite and muscovite belong to a family of platy minerals called “mica”. All have one strong cleavage and form sheets that you can pick apart with a knife or your fingernail. Micas strongly reflect light and appear shiny. Muscovite is also called “white mica” and biotite is sometimes called “brown mica” or “black mica”.

WebCleavage refers to the way some minerals break along certain lines of weakness in their structure. Mica is a good example – breaking along very closely spaced flat planes that yield thin "sheets." Calcite is another good example, breaking along three different planes that yield blocky fragments that look like a rectangular box that has been warped – called a …
