The elevated Au and Hg levels and hosts the Neumark arithmetic average is 1.6 mg/kg, the median value U deposit. Areas with Sb > 2.5 mg/kg include a Hainichen 0.9 mg/kg. The overall maximum concentration 30 km zone extending from the Silurian Lößnitz - amounts to 74 mg/kg, the minimum to 0.05 mg/kg. A Zwönitz syncline up to the Gera-Jachymov fault Project supported by: 2 km wide area with concentrations up to zone near Schneeberg and Schwarzenberg. Areas Sb > 10 mg/kg is located SE of Freiberg, coinciding with lower levels (Sb > 1.0 mg/kg) also extend far with elevated Pb, Zn and Ag levels. The latter area beyond the Hormersdorf Sb occurrence up to area s Freiberg merges into a zone of Sb > 4 mg/kg including the within gneisses and phyllites near to the fluorite- entire Freiberg mining district with an N-S-extension baryte deposits of Augustusburg and Grünberg . Dippoldiswalde of approx. 17 km. Furthermore, a NE-SW striking Further spots with Sb > 2.5 mg/kg occur arranged in zone with similar Sb levels occurs close to a half-circle around the Klingenthal-Kraslice Cu Hainichen. Here the Sb enrichment can be partially deposit. The northernmost location is related to the assigned to known Sb-mineralisation additionally Sn greisen deposits of Gottesberg-Mühlleithen, coinciding with strongly elevated Hg. Areas of whereas the western loc ations coincide with elevated Sb levels in the central Erzgebirge Ordovician metapelites where elevated Mo, Hg, Cd, accompany the known Sb occurrence of As and Se were detected. The areas with the lowest Hormersdorf SE of Stollberg. In the western part of concentrations (Sb < 0.4 mg/kg) are predominantly the study area Sb levels up to > 10 mg/kg occur at a bound to the granite plutons of Eibenstock an d 12 km NE elongated area NW of the Kirchberg Bergen, to Cambro-Ordovician metapelites south of Granite in faulted Ordovician and Devonian Adorf and to Neoproterozoic gneisses east and metapelites. northeast of Marienberg.
