文摘
- •
Raman spectra of charcoal fragments in cumulative soils were obtained.
- •
These spectra were compared to those of fresh charcoal fragments from a modern fire.
- •
There are spectrum differences among fresh charcoals and old and young soil charcoals.
- •
The differences imply the alteration or disappearance of charcoals in the soils.
- •
The charcoal residue rate in soils also depends on charcoal physical properties.
