Beschreibungen/Notizen

• The geochemical analysis of the REE hydrothermal apatite and scheelite pairs from various types of W ore deposits (skarns, disseminated scheelite, and quartz veins) provides an insight into REE partitioning between the two minerals. Among the 18 analysed pairs, only five appear to have grown in equilibrium conditions. Ten other pairs show more or less important departures from equilibrium. The remaining apatite and scheelite pairs have quite different REE patterns, indicating crystallization from different fluids.
