Malachite forms as a result of the weathering/oxidation of copper. In most locations, crystal formation begins when copperrich water (water containing dissolved copper) seeps through small cracks in rocks. The ideal rocks being limestone, for the breakdown of the limestone by the water provides the carbonate necessary for malachite formation.
Malachite is an intense green, copper based mineral that can be found in a wide variety of forms. Malachite can grow in botryoidal masses, stalactitic, and reniform formations, typically as a tight cluster of fanning fibrous needles that make up a seemingly solid mass.
