Summary

[edit]
Description
English: (A) SEM images of the surface of the black pustular mat where Rivularia filaments (Riv.) and exopolymeric substances (EPS) are observed. The red circle highlights a mineral aggregate with diatoms (Diat.). (B) Below the black pustular surface, mineral aggregates (Min.) with diatoms are abundant; some Rivularia filaments can also be observed. From (C–D), SEM images in backscattered electron mode of the carbonate minerals associated with the Rivularia filaments in BP mats. (C) Aggregates formed by sub-spherical to subhedral carbonate particles associated with the EPS matrix where diatoms frustules are also observed. (D) Magnified view of a mineral aggregate with subspherical carbonate grains and associated diatoms. (E) Aggregate composed of submicrometric carbonate spherules entombing abundant diatoms frustules. (F) Elongated needle-like carbonates.
