Fig. 1: Context view of fossil-bearing carbonate vein.
From: Microbial biosignature preservation in carbonated serpentine from the Samail Ophiolite, Oman
A split core view of vein from sample “BA1B 4-4 3-8”, sampled from 11.06 m depth. The red box shows the location of B (not to scale). B Petrographic view of the iron encrusted “polygonal zone” that contains fossilized microbial biosignatures. The matrix is composed of aragonite (labeled “arag”), and a brecciated waxy green serpentine (labeled “srp”) clast bounds the bottom margin of the polygonal zone. The locations of Frutexites-like microstromatolite structures are indicated by arrows.
