Malý Uran,
Location of the heap of former uranium mine from the 1950s is situated about 70 m from the edge of a relatively sparse oak forest. The area affected by mining work is about 60x30 m large. There is a heap of about 15x15 m, about 5 m high, on a gentle slope. The heap is dominated by 99% fresh fragments (10-25 cm) of dark gray, sometimes finely laminated schist. Fragments of dark porphyry with phenocrsts of quartz (probably granite porphyry) and fragments of gray quartz are rare. The heap has only slightly increased radioactivity. Above the heap is about 20 m long and up to 2 m deep partially overgrown and sunken notch, in the direction of 170 °, most likely a trench dug along the mineralized zone. The material around the yard has the highest activity in the whole locality. The measurement showed: K = 3.4 wt. %, U = 112 ppm, Th = 7.4 ppm, magnetic susceptibility varies between 0.10-0.17 x 10-3 SI. About 10 m above this groove is a transverse digging roughly in the E-W direction about another about 10-15 m further in the same direction. These are transverse diggings, in the direction of mineralization there is an increased radioactivity, but only weakly. | Žáček, Vladimír | 2020
