Fig. 2: Stratigraphy and geochemical proxies of Stensiöfjellet section.
From: Wildfire, ecosystem, and climate interactions in the Early Triassic
A Stratigraphic column with ages and members of the (B) Stensiöfjellet section with the depth color code. The Lusitaniadalen Member consists of a light sandy shale, and the Vendomdalen Member consists of a darker silty shale24. C The δ13Corg (VDPB, ‰) in blue, TOC (wt%) in green, (D) phenanthrane (ug/g TOC) in orange with the gray stippled line representing the down section average value, (E) benzo[ghi]perylene (ug/g TOC) in purple with the gray stippled line representing the down section average value, (F) methyphenanthrane index (MPI-1) in light brown, (G) terrestrial-aquatic ratio (TAR) in light blue with arrow indicating decrease of terrestrial organic matter input, and (H) light molecular weight (LMW) over total PAHs in gray, arrow indicates increase in smoke derived PAHs with the dashed line representing the transition between residue and smoke6. I Spore/Pollen ratio reflecting the change from Lycophyte (spore producing) to Gymnosperm (pollen producing) dominated vegetation from the Svalis Dome compiled from Hochuli and Vigran52 shown in light green, and from the Stensiöfjellet section in dark green51. The light shaded line in diagrams (C–H) represents a 3-point moving average.
