Early Magmatic Deposits. So this process would require early crystallization of additional Ferich phases to raise the Fe/Mg ratio of the early crystallizing assemblage Likely candidates for the Ferich phase or phases would be magnetite or an Ferich amphibole Experiments conducted in the 60s through 80s failed to show that magnetite or Ferich amphibole would be early crystallizing phases in basalts or.

Uranium ore deposits are economically recoverable concentrations of uranium within the Earth’s crustUranium is one of the more common elements in the Earth’s crust being 40 times more common than silver and 500 times more common than gold It can be found almost everywhere in rock soil rivers and oceans The challenge for commercial uranium extraction is to find those.
