• It can be deduced from fluid inclusion data that the ore forming fluid is polysaline with homogeneization temperatures between 111 and 156ºC and 16.3 %wt eq NaCl average salinity. On the other hand, REE distribution patterns are very similar suggesting the same source as well as fluorite deposition in an open environment. Preferential concentration of LREE implies a primary REE normalization patterns.
