Microbially induced sedimentary structures, or MISS, are sedimentary structures produced by synsedimentary deformation of unlithified flexible cohesive sediment-binding mats. Microbial mats bind, biostabilize, baffle, and trap sediments, resulting in characteristic structures that cannot be formed by pure physical/chemical processes (Fig. 6 E).Another problem with siderite nodules is that they often include the surrounding sediment often making it a sideritic bound sedimentary concretion.
