Stratigraphic charcoal analysis on petrographic thin sections : application to fire history in northwestern Minnesota

Auteur :
CLARK, J. S.

Description :
Results of stratigraphic charcoal analysis from thin sections of varved lake sediments have been compared with fire scars on red pine trees in northwestern Minnesota to determine if charcoal data accurately reflect fire regimes. Pollen and opaque spherule analyses were completed from a short core to confirm that laminations were annual over the last 350 yr. A good correspondence was found between fossil-charcoal and fire-scar data.
