... in the centre of a 1.5-m-wide shear zone (average trend 135 degrees) with shifts of a few cm. In 1988, the selenium mineralization consisted of a single vein, ranging mostly from 0.5–2 cm in thickness. The El Dragόn mineralization is composed of a complex assemblage of primary and secondary minerals, among...

The evolution of hydrothermal fluids, from which Se mineralization formed, suggests a distinct enrichment in sulfur and depletion in selenium over the time span of crystallization. A small amount of Hg-hakite was ground under ethanol in an agate mortar and a suspension was deposited onto a TEM...
