hi there dusted,
a friend of mine gave me this rock...
what do you think it is?
thanks in advance
M8 its some very nice mica sheets! in Quartz.. The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having close to perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
The word "mica" is derived from the Latin word mica, meaning "a crumb", and probably influenced by micare, "to glitter".[1]
Ive seen mica sheets used as window panes in peru.. but still very pretty rock!
