Apatite – Geology In
Lunar science. Moon rocks collected by astronauts during the Apollo program contain traces of apatite. Re-analysis of these samples in 2010 revealed water trapped in the mineral as hydroxyl, leading to estimates of water on the lunar surface at a rate of at least 64 parts per billion – 100 times greater than previous estimates – and as high as 5 parts per million.

Apatite in carbonatitic rocks: Compositional variation, …
The structure of apatite is tolerant to a wide range of substitutions (Table 1).Some of the large substituent cations are accommodated preferentially either in the ninefold-coordinated Ca1 site, or the Ca2 site coordinated by six oxygens and F (± OH ± Cl).Element partitioning between Ca1 and Ca2 in chlorapatite differs from that in fluor- …

Apatite: A Mineral for All Seasons
Apatite is a widespread accessory mineral in igneous, metamorphic, and clastic sedimentary rocks and can be dated using four radioactive decay schemes, each with a different temperature window for isotopic closure: Lu–Hf (675–750 °C); U–Pb (350–550 °C); apatite fission track (60–110 °C); (U–Th)/He (40–80 °C).

Apatite: New Finds at Pulsifer Quarry | Rock & Gem Magazine
Apatite occurs in a variety of geological environments but can be well developed in granitic pegmatites. It may be colorless, white, brown, green, yellow, blue or purple. In apatite, the purple color is caused by manganese. Purple apatite is found in a number of localities around the world, including several in Maine.
