Raman analysis of analogue mudstone samples. Panels A and B are Raman maps of lake-community inoculated sample pellets. Panel C is a Raman map of Bacillus subtilis inoculated sample pellet. Each colour shows the integrated peak area between a minimum and maximum wavenumber. Red = 1375–1469 cm−1, Green = 1478–1575 cm−1, Blue = 1591–1722 cm−1.
