    The occurrence, concentration and geochemistry of REE-bearing minerals in beach sands along the West Coast of the South Island of New Zealand is reported as a proxy for the composition of adjacent uplifted Holocene marine terraces. The strandlines of 13 beaches along this coast contain REE-rich allanite (average: 15% REO), monazite (82% REO) and

  • “Mineral Sands Deposits: their complexity and need for International reporting standards Indian scenario”

    Presented by Deepak Rathod. The term “Mineral Sands” refers to sands which contain suites of minerals with high specific gravity (> 4 Specific Gravity) known as heavy minerals. Heavy minerals occurs as disseminated, associated or concentrated deposits within the sands. Found in an alluvial (old beach or river system) environment.
