  • Same as alkaline.
  • Specifically applied to the minerals of igneous rocks (in the quantitative classification) or to magmas and rocks generally, when specially characterized by their alkali contents: in distinction from alkaline, which implies the chemical property of alkalinity.

  • Concentrations of the REE's have been identified within phosphate minerals from the project such as carbonated monazite, dahllite, apatite and fluorapatite genetically associated with the alkalic sill complex.
