Field of View: 0.5 mm
The microstructure of high-grade silver ore from Příbram District.
Amazing symplectic intergrowth of chalcocite (grey) and galena (white), with inclusions of tetraedrite (olive-brown) and stromeyerite (violet-grey). Polished section, vertically reflected plane polarized light digital image in air.
Ore microscopy illuminates the darkness of the “grey ugly” with true reflectance colors!
Please compare the corresponding photomicrographs.
