Malachite from
Conrad Hill Mine (Dodge Hill Mine), Cid Mining District, Carolina Slate Belt, Davidson Co., North Carolina, USA

Locality type:Mine
Classification
Species:Malachite
Formula:Cu2(CO3)(OH)2
Formation:Secondary
Comments:Malachite is common as small patches and stains, often with chalcopyrite. But within the void spaces of the cellular goethite, nice acicular crystals and silky or velvety sprays can be found with diligence. In the 1970's I (Steve Adams) broke open a piece of such goethite and was astonished to see a spray of several needles of malachite fine as a hair rising from a point a full inch tall! But holding it up in admiration, a strong wind gust came along and broke the crystals away!
Quality for species:Good crystals or rich for species - important (!)
Significance:Unusual or interesting association, relationships with other species, pseudomorphism etc. - see notes.
Abundance at site:Common
Confirmation
Validity:Believed Valid
