Brochantite is Cu4(OH)6SO4
Brochantite is a basic sulfate of copper.  It is often mistaken for the mineral malachite,
but brochantite has a touch more blue to its green color than malachite.  This
specimen came from the open pit in Morenci, Arizona.  The rock split in half along a
pre-existing crack where the starburst patterns of brochantite had formed.  Each
starburst is about 1 centimeter across.
