Field photos and photomicrographs of some important sedimentary structures in supratidal setting. (a) Polygonal mud cracks in the Top Quartzite. (b) Mud cracks on the rippled sandstones that show upper intertidal conditions. (c) Large-scale mud cracks in the supratidal deposits (Top Quartzite). (d) V-shaped mud cracks in carbonate tidalites (Deranjal Formation). (e) Shrinkage and polygonal mud cracks in supratidal setting of the Padeha Formation. (f) Syneresis cracks in the Padeha Formation. (g) V-shaped cracks in mudstone petrofacies (Padeha Formation). (h) V-shaped cracks in dolomudstone microfacies (Padeha formation). (i) Raindrop imprints in the muddy sediments of the Padeha Formation. (j) Salt casts or halite casts in the Padeha Formation. (k), Enterolithic folding in the evaporite deposits (Padeha Formation).
