  1. Apatite emissions range from bluish-violet, lilac, pink and orange to yellow.
  2. Depending on the activator, a single excited mineral may radiate at several different wavelengths; for example, apatite CL may be green, yellow, pink, violet or white, with a variety of rare earths acting as activators.
  3. The quartzo-feldspathic gneiss contains quartz, feldspar and hornblende as the principal minerals, variable though small amounts of biotite, and with iron ores and apatite as the common accessory minerals present.
  4. The thermal history of the South Mountains Granodiorite, provided by isotopic (U-Pb zircon, 40 Ar/ 39 Ar hornblende, K-Ar biotite) and fission-track (apatite) age determinations, indicates rapid cooling of 260CMyr -1 (from 800 to 300C) between 22 and 20Myr ago, followed by slower cooling of 73CMyr -1 (from 300 to 100C) between 20 and 17Myr (ref. 24).
  5. The metamorphism resulted from the spontaneous in-situ combustion of these organic-rich sediments and has produced a complex assemblage of minerals including quartz, wollastonite, spurrite, ellestadite, apatite, brownmillerite, magnetite, hematite, calcite and various oxides and ferrite minerals.
  6. Concentrations of apatite, magnetite, and base metals (Notholt and others, 1985) have aroused interest from time to time.
  7. It is also important, with porous rocks, to remove carefully all traces of the diamond polishing abrasives from the slide: industrial diamond grains have a brilliant green CL which produces halation spots, giving the impression of a larger grain, which is apt to be mistaken for an apatite or other heavy mineral gram.
  8. The apatite crystals are also much smaller being 200-;300 long and 40-;70 wide.
  9. These apatite crystals are embedded in an organic matrix which is mostly collagen.
  10. These veins contain diopside and phlogopite, with minor disseminated ilmenite, zircon, calcite, apatite and serpentine.
