VESUVIANITE – POTENTIAL INDICATOR MINERAL OF MINERALIZED SKARNS?

Popis výsledku v původním jazyce

Vesuvianite is a typical mineral for contact metamorphic and metasomatic rocks – skarns, rodingites, skarnoids. Its composition depends on several factors – bulk composition of the intrusive rock and its metasedimentary host, composi-tion of reacting fluids, and PT-conditions. Vesuvianite structure is complex and accommodates a large number of various elements – its general formula is X19Y13Z18T0-5O68W10, where X = Ca, Na, Ln3+, Pb2+, Sb3+; Y = Al, Mg, Fe3+, Fe2+, Ti4+, Mn, Cu, Zn, As3+; Z = Si; T = B; and W = OH, F, Cl, O [1,2,3]. We studied chemical (major, minor and trace elements) com-position of vesuvianite from skarns at 5 selected localities from the Bohemian Massif. VESUVIANITE COMPOSITION The studied samples are compositionally heterogeneous with variable Fe/Mg ratio, Al/R2+ ratio, and variable contents of Ti, Na and F within each locality; core-to-rim zoning was locally observed (increase of Fe, Be, B, Zn, and Sn, decrease of Al, Mg, and F).
