  • Rare Earths

    Among this group however are a few of the rarest elements known. Perhaps best known of the group are cerium and yttrium. Monazite sand a by-product of heavy-mineral processing is the most important mineral source of the rare-earth group. Deposits of the minerals bastnaesite and xenotime are also important sources of certain rare earths.

  • CalciteWikipedia

    Calcite seas existed in Earth history when the primary inorganic precipitate of calcium carbonate in marine waters was low-magnesium calcite (lmc) as opposed to the aragonite and high-magnesium calcite (hmc) precipitated today. Calcite seas alternated with aragonite seas over the Phanerozoic being most prominent in the Ordovician and Jurassic.
