Peacock Ore | WhatAEarth

Peacock Ore (Bornite) is a crystaline variety of Chalcopyrite and they have very similar properties. Bornite is a copper iron sulfide mineral commonly found in hydrothermal veins, contact metamorphic rocks and in the enriched zone of sulfide copper deposits. It is a common ore of copper and is easily recognized because it tarnishes to iridescent shades of blue, purple, green and yellow.

Bornite is an ore mineral of copper, and is known for its iridescent tarnish. "Peacock Ore", which is sold to amateur mineral collectors and tourists, is often labeled as a variety of Bornite.However, most Peacock Ore in reality is Chalcopyrite treated with acid, which produces a strongly-colored iridescent tarnish.Bornite is named for Ignatius von Born, an Austrian mineralogist and ...

Magnetite - Wikipedia

Magnetic properties. Lodestones were used as an early form of magnetic compass. Magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in understanding plate tectonics and as historic data for magnetohydrodynamics and other scientific fields.
