文摘
- •
The validity of classical single component geochemical maps is discussed.
- •
Geochemistry data are compositional and contain inherently multivariate relative information.
- •
Knowledge-driven log-ratio approaches are introduced.
- •
Geologically meaningful log-contrasts are presented.
- •
A chain of enquiry is recommended to ensure a complementary compositional approach.
