Photo by John Jairo Zamora. The authors recently examined a rough emerald crystal specimen (figure 1), measuring 18.35 × 10.69 × 9.79 mm, reportedly from Chivor. This crystal weighed 3.22 g (16.10 ct) and had a prismatic hexagonal crystal shape. Standard gemological examination confirmed the gemstone to be emerald, and ultraviolet/visible/near-infrared (UV-Vis-NIR) spectroscopy showed a classic Colombian emerald absorp- tion spectrum. -

Formation of Chrysocolla and Secondary Copper Phosphates in the Highly Weathered Supergene Zones of Some Australian Deposits
Records of the Australian Museum (2001) Vol. 53: 49–56. ISSN 0067-1975 Formation of Chrysocolla and Secondary Copper Phosphates in the Highly Weathered Supergene Zones of Some Australian Deposits MARTIN J. CRANE, JAMES L. SHARPE AND PETER A. WILLIAMS School of Science, University of Western Sydney, Locked Bag 1797, Penrith South DC NSW 1797, Australia [email protected] (corresponding author) ABSTRACT. Intense weathering of copper orebodies in New South Wales and Queensland, Australia has produced an unusual suite of secondary copper minerals comprising chrysocolla, azurite, malachite and the phosphates libethenite and pseudomalachite. The phosphates persist in outcrop and show a marked zoning with libethenite confined to near-surface areas. Abundant chrysocolla is also found in these environments, but never replaces the two secondary phosphates or azurite. This leads to unusual assemblages of secondary copper minerals, that can, however, be explained by equilibrium models. Data from the literature are used to develop a comprehensive geochemical model that describes for the first time the origin and geochemical setting of this style of economically important mineralization.
