Os minerais de mica distinguem-se pela sua clivagem basal perfeita, o que significa que são facilmente divididos em folhas finas, muitas vezes transparentes. Duas micas, biotita e moscovita, são tão comuns que são consideradas minerais formadores de rocha . O resto é relativamente incomum, mas a flogopita é a mais provável de ser vista
