Enterolithic structures are stratigraphically localized folds in gypsum beds found in certain
saline evaporitic sedimentary units in a wide variety of basins. Different models of formation
have been proposed, all related to inorganic processes. These models include: diagenetic
transformation of gypsum beds producing either displacive growth of crystals or volume
changes; mechanical folding caused by compressional stress; and folding produced by
slumping. The analysis of three Cenozoic evaporite sequences in Spain reveals that none of …

the proposed model could explain the existence of Kinneyia‐type structures, also known as
wrinkle structures, formed beneath microbial mats in peritidal zones. Moreover, considering
enterolithic structures as microbially induced sedimentary structures could be useful as
evidence of microbial life in the ancient geological record and on other planets such as Mars. …
