Yet, little is known about the taphonomy of charcoal in soils. Here, we assessed the putative loss of palaeoecological information due to charcoal fragmentation after burial. We found no significant loss of charcoal mass with time. Instead, we found a significant positive relationship between the mass of charcoal particles and their age. Permineralization of charcoal particles older than ca. 5200 a explained the increased charcoal mass with time in mineral soils. The permineralization process increased the density of charcoal particles (resulting in a two-fold increase particle mass) and, thus, offers a protection against subsequent degradation. Our results suggest high stability of palaeoecological information from charcoal macrofossils buried in mineral soils at least over the Holocene timescale.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in Journal of Quaternary Science, 26: 571-575.
