In this interval, zircon Yb/U, Lu/Nd, and Ce anomaly all follow the same general inverted Ushaped pattern as zircon ε Hf(i): relatively low values at ca. 1800 Ma (, Aileron province ages in central Australia), a subsequent rise that reaches an apex at ca. 1400 Ma (partially captured by central Australia data, but best represented by ...

Heavy mineral sands ore deposits

Heavy mineral sands ore deposits

+

Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rareearth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
