摘要：
A sediment profile containing charcoal fragments was discovered in a swampy area in the region of central Brazil; the sequence includes most of the Holocene and testifies to the existence of a period of significant wildfires during the Middle Holocene. These fires, at the origin of today's savanna, took place during the beginning of a dry climatic period around 6,000 BP. The recovery of the partly-deciduous mesophilous forest takes place around 3,000 BP. Modern deforestation began after 600 BP.
