A 2D Raman phase maps for quartz (465 cm–1), carbonaceous materials (CM; 1600 cm–1), carbonate (1090 cm–1), rutile (610 cm–1) and phyllosilicates (mapped as the O–H band; 3620 cm–1). B Fourier transform infrared spectroscopy (FTIR) maps for aromatic carbon (C=C; 1600 cm–1) aliphatic carbon (CH2 and CH3; 2870, 2930, 2960 cm–1) and phyllosilicates (mapped as the 3650 cm–1 O–H stretch).
