Compositional data analysis in geochemistry: are we sure to see what really occurs during natural processes?
A Buccianti, E Grunsky - Journal of Geochemical Exploration, 2014 - Elsevier
Geochemical data are typically reported as compositions, in the form of some proportions
such as weight percents, parts per million, etc., subject to a constant sum (eg 100 …
