Plot of whole rock Sn content (ppm) against zircon Eu/Eu*. Blue shading represents a “threshold” level of Sn, suggesting a zircon Eu/Eu* of 0.08 or less may indicate elevated Sn values and the potential for the development of tin mineralization. Also plotted on the y-axis are aggregated and bucketed whole-rock Sn contents reported for major tin deposits from Southeast Asia (Malaysia and Thailand), the Erzgebirge, Bolivia, Portugal, Nigeria, and the Massif Central, as summarized in Lehmann (1990)19.
