Group of geocronite-jordanite crystals, with striated pseudohexagonal shapes, very bright and rich in facets. The matrix is ​​mainly composed of geocronite-jordanite, with various cavities where we observe striated crystalline faces.The analyzes show a correlation between geocronite-jordanite, both are isostructural and form series. Crystals analyzed show that the composition moves in the intermediate zone of the series. The geocronite-jordanite crystals are accompanied by sphalerite, galena, associated with transparent crystals of green fluorite.
