Abstract
The authors received two unusual crystals of epidote from Rock Currier, Jewel Tunnel Imports, in 2012. The mineral specimens were collected at Zard Mountain (Zard Koh), in the central part of the Ruskoh Mountains (Rusk Koh), west of Kharan, Balochistan, Pakistan (written communication, Rock Currier, 2013). The epidote locality was most likely discovered in 2010. These epidote crystals were unusual in both form and composition. The large crystals were flat tabular and pseudohexagonal in shape which is an uncommon crystal form for a monoclinic mineral (fig. 1). Other specimens from the same locality have been described as pseudo-octahedral in shape. The two crystals range in size from 5.5 to 6.5 centimeters (2.2 to 2.6 inches) and are slightly magnetic. The epidote crystals have a core matrix that resembles a weathered igneous rock. Some micro brown- to reddish-titanite crystals were observed under a binocular microscope on the surface and core areas of the crystals (figs. 2 and 3). Other minerals observed in the core areas include feldspar, biotite, and quartz. The crystals display evidence of cluster-growth with points of attachment to other crystals. The epidotes were most likely collected in pockets of a weathered igneous-skarn deposit.
