Boron isotopes in Palaeoarchaean tourmaline show evidence for multiple boron sources.
- class="label">•
Boron sources are Archaean seawater, Archaean oceanic crust, and a third isotopically light source.
- class="label">•
The latter may reflect remobilized boron derived from mature continental crust or isotopically light seawater (10–15‰).
