Group of geocronite-jordanite crystals, with striated pseudohexagonal shapes. They have a lighter gray sheen than the galena with which they are often associated. The analyzes show a correlation between geocronite-jordanite, both are isostructural and form series. The crystals analyzed (both these that we present and others) show that the composition moves in the intermediate zone of the series. Therefore, the correct thing would be to label these specimens as geocronite-jordanite, avoiding saying that they are only geochronite. We will send all analyzes to the buyer.
The geocronite-jordanite crystals are accompanied by crystals of sphalerite, of galena, associated with transparent crystals of green fluorite, both cubo-octahedral, the latter truncated by the faces of the cube and the trapezohedron.
