“…The samples of the fossil charcoal from Faxinal are also located in the cluster of temperatures above 400ºC, but tend to higher temperatures in the PCA, showing a different behavior from fossil charcoal samples of Belvedere. Kubik et al (2020) presented studies of fossil charcoal samples collected from the outcrops of Quitéria and Belvedere curve, both from the same origin of sedimentary deposition in the Paraná Basin, and related to the Permian Period. The result of the study, which was carried out by chemical characterization of biomaterials, inferred on analyzed samples regarding the environment of the deposition, origin of the organic matter and possible type of forest fire.…”

The main objective of this study was to develop a methodology to evaluate, by physical and chemical methods, artificially charred logs from three species of Araucariaceae, and compare them fossil charcoal collected in the Faxinal and Belvedere outcrops for possible paleoenvironmental inferences. The species studied were Araucaria angustifolia, Araucaria bidwillii and Araucaria columnaris. For fossil charcoal analyses we used samples from the Mina do Faxinal and samples from the Curva do Belvedere Outcrop. The carbonization process from species of Araucariaceae were Thermogravimetric Analysis (TGA) associated to the techniques of Fourier Transform Infrared Spectroscopy (FTIR) and multivariate analysis. The Principal Component Analysis (PCA) showed that it is possible to describe 90,9% of the data, grouping the samples into two main clusters. Both samples of fossil charcoal from Belvedere and Faxinal showed charring characteristics above 400ºC. Results showed that technical associations, such as TGA, FTIR and multivariate analysis may help to characterize the natural carbonization process and contribute to important paleoenvironmental and archaeological information and inferences.

Fire is a major driver for the evolution of biodiversity throughout the Phanerozoic and occurs in continental palaeoenvironments since the advent of the first land plants in the Silurian. The detection of palaeo–wildfire events can be based on different proxies, and charcoal is widely accepted as the most reliable evidence for such events in sedimentary layers. Although the identification of sedimentary charcoal as the product of incomplete combustion was the subject of controversial scientific discussions, palaeobotanical data can be used to confirm the pyrogenic origin of such material. In an overview on Palaeozoic and Mesozoic charcoal remains, differences in the number of published records can be detected for individual periods; including phases with both, lower (Silurian, Triassic, Jurassic) and higher (Devonian, Carboniferous, Permian, Cretaceous) numbers of published evidences for palaeo–wildfires. With the aim to discuss selected advances in palaeo–wildfire studies since the beginning of the 21st Century, we present an overview on the published occurrences of charcoal for an interval from the Silurian up to the Cretaceous. It was possible to confirm that a lack of detailed palaeobotanical data on the subject is detected in some intervals and regions, despite the high potential of occurrences detected in form of pyrogenic inertinites by coal petrographic studies. Although such temporal and regional gaps can be explained by taphonomic and palaeoenvironmental biases, it also indicates the scientific potential of future studies in diverse palaeogeographical and temporal settings.

“…Os grandes fragmentos de lenhos queimados, em Faxinal, se distinguem dos centimetricos e milimetricos fragmentos de macro-charcoal, presentes, de forma recorrente, em bandas densas, nos a loramentos de idade Asseliana, em Quiteŕia e em Curva do Belvedere, cuja faciologia é relacionavel a pântanos lagunares e a terras baixas (Kubik et al, 2020). Esses macro-charcoals seriam provenientes, provavelmente, de incendios regionais, que ocorriam em fases cıćlicas, e teriam sido transportados, por via aquática, até as áreas de deposição.…”
