Source for "Relative abundance of elements in the Earth's upper crust."[edit]

Hello, I am a student doing a project on rare earth elements and I would like to know, if it is possible, what was your scientific source while doing the illustration on "Relative abundance of elements in the Earth's upper crus".

Have a nice day, and take care. 2A01:E34:EC1A:B80:9959:A57F:839A:5FF8 07:37, 11 October 2022 (UTC)[reply]

Hello, I used https://pubs.usgs.gov/fs/2002/fs087-02/ as a source.
Good luck with your project! Michbich (talk) 07:43, 11 October 2022 (UTC)[reply]


what is the logarithm shaped part of the curve under the hysteresis section supposed to represent? is it a accidental inclusion?
