Sc redistribution during post-magmatic processes in the Cinovec/Zinnwald deposit
Original language description
Post-magmatic processes on Li-Sn-W deposit Cinovec/Zinnwald were studied in order to assess Sc behaviour during alteration of Sc-enriched phases and other mineralogical changes. Focussing on the main rock types of the deposit, we describe several different alteration mechanisms that affect the most important carriers of scandium - zircon, columbite, woiframite, ixiolite, scheelite, zinnwaldite, and muscovite. The alterations include: 1) replacement of zinnwaldite (avg 63 ppm Sc) by muscovite (avg. 25 ppm Sc) 2) sheelitization of Sc-rich wolframite (0.58 wt% Sc2O3). The scheelite contains low Sc and is spatially associated with Sc-rich (up to 4.87 wt% Sc2O3) ixiolite. 3) Alteration of zircon possibly leading to Sc-enrichment 4) Replacement of wolframite I by Mn-dominant Sc-poor wolframite II. From above listed minerals, only wolframite and its Sc-bearing breakdown products are the most likely to have possible economic significance for Sc extraction.
