It has been suggested by various workers that an extraterrestrial impact at the K–T boundary delivered sufficient thermal power to ignite globally extensive wildfires. Numerous models have sought to predict the amount of thermal power released by the impact, but none have considered the distribution of wildfire indicators in K–T rocks. Probably the most distinctive product from combustion of biomass is charcoal. The abundance of charcoal across the K–T boundary at eight non-marine sites in…

Geochemical evidence for combustion of hydrocarbons during the K-T impact event
It is revealed that the K-T BIRs have a pPAH signature consistent with the combustion of hydrocarbons and not living plant biomass, providing further evidence against K- T wildfires and compelling evidence that a significant volume of hydroCarbons was combusted during theK-T impact event.
An experimental assessment of the ignition of forest fuels by the thermal pulse generated by the Cretaceous–Palaeogene impact at Chicxulub
A large extraterrestrial body hit the Yucatán Peninsula at the end of the Cretaceous period. Models suggest that a substantial amount of thermal radiation was delivered to the Earth’s surface by the
K‐Pg extinction: Reevaluation of the heat‐fire hypothesis
The global debris layer created by the end‐Cretaceous impact at Chicxulub contained enough soot to indicate that the entire terrestrial biosphere had burned. Preliminary modeling showed that the
Revisiting wildfires at the K‐Pg boundary
The discovery of large amounts of soot in clays deposited at the Cretaceous‐Paleogene (K‐Pg) boundary and linked to the ~65 Ma Chicxulub impact crater led to the hypothesis that major wildfires were
Organic matter from the Chicxulub crater exacerbated the K–Pg impact winter
Characteristics of polycyclic aromatic hydrocarbons in the Chicxulub crater sediments and at two deep ocean sites indicate a fossil carbon source that experienced rapid heating, consistent with organic matter ejected during the formation of the crater, and size distributions proximal and distal to the crater indicate the ejected carbon was dispersed globally by atmospheric processes.
Combustion of fossil organic matter at the Cretaceous-Paleogene (K-P) boundary
Recognition of elevated concentrations of aciniform soot in Cretaceous-Paleogene (K-P) boundary sediments worldwide led to the hypothesis that global-scale forest wildfires could have been generated

Abstract. The analysis of charcoal fragments in peat and lake sediments is the most widely used approach to reconstruct past biomass burning. With a few exceptions, this method typically relies on
Self-shielding of thermal radiation by Chicxulub impact ejecta: Firestorm or fizzle?
As hypervelocity ejecta from the Chicxulub (Yucatan, Mexico) impact fell back to Earth, the surface may have received a deadly dose of thermal radiation sufficient to ignite global wildfires. Using a
Impacts and Wildfires - An Analysis of the K-T Event
Models of the Cretaceous-Tertiary (K-T) impact at Chicxulub have suggested that thermal radiation would have been sufficient to have ignited extensive or near global wildfires. The discovery of


Fireball passes and nothing burns—The role of thermal radiation in the Cretaceous-Tertiary event: Evidence from the charcoal record of North America
High soot contents have been reported in Cretaceous-Tertiary (K-T) sedimentary rocks, leading to the suggestion that the amount of thermal power delivered from the Chicxulub impact was sufficient to
Major wildfires at the Cretaceous-Tertiary boundary
K-T boundary clays from five sites are enriched in soot and charcoal by factors of 100-1000 over Cretaceous levels, apparently due to a global fire, implying that the fire was triggered by the impact.
The global Cretaceous-Tertiary fire: Biomass or fossil carbon
The global soot layer at the K-T boundary indicates a major fire triggered by meteorite impact. However, it is not clear whether the principal fuel was biomass or fossil carbon. Forests are favored
Trajectories and distribution of material ejected from the Chicxulub impact crater: Implications for postimpact wildfires
[1] The trajectories of low- and high-energy ejecta from the Chicxulub impact crater have been computed using a numerical code and compared with analyses of debris deposited in K/T boundary sections.
Organic geochemical evidence for global fires at the Cretaceous/Tertiary boundary
MANY hypotheses have been advanced to explain the mass extinction at the Cretaceous/Tertiary (K/T) boundary1–3. Recently, Wolbach et al. 4 suggested that massive forest fires were triggered by the
