Pre-Quaternary Records of Wildfirefying the authenticity of fossil charcoal was done with Mesozoic charcoals, and charcoal is abundant in some Mesozoic sediments. However, almost nothing has been deduced about the fire ecology of Mesozoic environments. By the standards of more ancient sediments, fossil charcoal is present, but scarc

Marine Sediments: A Reservoir for Black Carbon and their Use as Spatial and Temporal Records of Combcean. BC deposition to the ocean surface is much more homogeneous throughout the ocean, accounting for deposition of 6.9 Tg BC yr.. We hypothesize that rivers may transport 12.2 Tg BC yr. to the ocean and that these particulates are largely deposited in coastal ocean sediments. The manuscript discus

Reconstructing Environmental Impacts of Fire from the Holocene Sedimentary Recordution stratigraphical data and quantitative palaeoenvironmental reconstructions with a high precision. As is so often the case in palaeoecology, alternative hypotheses may be possible to explain observed stratigraphical patterns. Statistical techniques such as constrained ordinations, variance parti

Their application requires knowledge of the relations of the Wyckoff positions of group-subgroup related structures. ..(3)
