Zirconium in stream sediments

Zirconium (Zr) shows a right skewed log distributio n Eibenstock massif as well as the Kirchberg granite with two maxima at about 0.5 mg/kg and 1.5 mg/kg. do not indicate contrasts with their metasedimentary Hainichen The maximum concentration is 55 mg/kg, the surroundings . Moreover, the Bergen and minimum 0.25 mg/kg. The arithmetic average is Fichtelgebirge plutons show even Zr minima. The 1.6 mg/kg versus a median of 1.0 mg/kg. Zr is northern Erzgebirge rim, including lower P aleozoic Project supported by: controlled by lithology, mainly by Upper metasediments, shows only slight elevations of Carboniferous granitoids and metabasites. Parts of Zr > 1.6 mg/kg, interrupted by a narrow , NNE distinct granitoid intrusions show significant striking enrichment zone east of Hainichen. This Freiberg differences in Zr content. The overall highest leve ls zone is predominantly related to Proterozoic were recorded at the Schellerhau granite and parts metavolcanics and Devonian volcanic rocks. The Dippoldiswalde of the adjacent Teplice rhyolite within a 3 km NW large area of low concentrations with Zr < 0.6 mg/kg trending zone of Zr > 10 mg/kg. The latter zone is in the eastern Erzgebirge corresponds to surrounded by a fringe zone of Zr > 6.0 mg/kg Neoproterozoic and lower Paleozoic gneisses. covering the main parts of the Schellerhau intrusio n. Zones with contents up to Zr > 4.0 mg/kg occur in sedimentary and volcanic rocks of Devonian units
