“Mottled light brown corderoite crystal on black unidentified mineral (probably Mn or Fe oxide-hydroxide) and surrounded by smaller blocky corderoite crystals and acicular crystals of kenhsuite. The orange phase on the crystals is not identified (probably iron hydroxide such as limonite), as well as the blue-green phase (probably malachite). Corderoite from this location has been confirmed by pxrd. Kenhsuite is the gamma (y) polymorph of Hg3S2Cl2. Photo taken with Leitz Orthoplan microscope fitted with Leitz Ultropak 6.5x objective and Sony A7R camera mounted to triocular phototube. Illumination was provided by a 50W halogen bulb in the standard illumination housing. 158 individual images were stacked with Zerene software to produce the final image, which was then processed for color accuracy and to remove lighting and dust artifacts. ”
