“…Volumic magnetic susceptibility (K) was determined using the SM30 portable instrument, which is more modern and sensitive but has the same overall geometric design as the KT5 used by Williams-Thorpe. The sensor diameter is about 5 cm and probes the material down to a few centimeters in depth: the first centimeter already provides 69% of the total signal (Lecoanet et al, 1999;Jordanova et al, 2003;Gattacceca et al, 2004b). At least three K measurements were obtained by applying the sensor to several cylindrical surfaces, selecting the smoothest possible area.…”

International audienceWe present a magnetic study of palaeohearths within Lazaret cave (Nice, France) that demonstrates how to recognize fired structures in similar geological contexts. Using magnetic field and susceptibility mapping, excavated and potentially still-buried palaeohearths of the cave are investigated. Our study reveals some difficulties in conducting a magnetic field survey to detect combustion features in a cave due to noise and ambiguities in anomaly assignment. To overcome these difficulties, discrete measurements and a specific post-processing methodology were applied to remove the magnetic noise generated by surrounding artificial sources. In addition, experimental and numerical modelling constrained by laboratory examinations of the magnetic mineralogy were performed to better identify the magnetic imprint of such fireplaces. We confirm that a short-term fireplace produces a thin ash-bearing layer characterized by a high magnetic susceptibility and a high frequency dependence due to a large proportion of grains of pseudo-single-domain (PSD) size. Such a burnt soil layer is the main source of the ca. 50 nT amplitude magnetic field anomaly at a sensor height of 15cm observed over the excavated palaeohearth, as well as over an experimental hearth.
