This will eventually be some interesting text about Lunar copper. Right now I just wanted to park some data and resources I found while writing Book 1.
Data
Abundance (mare basalts)
- About 10 μg/g of copper in mare basalts [1, pg 417}

- From one paper (2)
- 3.3±0.3 ppm (6 analyses)
- 7.1±2.1 (5 analyses)
- 10±2 ppm (19 analyses)

Resources
- Lunar Sourcebook
- Isotopic and Elemental Abundances of Copper and Zinc in: Lunar Basalts, Glasses, and Soils, a Terrestrial Basalt (https://www.lpi.usra.edu/meetings/lpsc2007/pdf/1222.pdf)
