Morphology and Distribution of Miss: A Comparison between Modern Siliciclastic and Carbonate Settings

Effects of 2010 Hurricane Earl amidst geologic evidence for greater overwash at Anegada, British Virgin Islands

“…S6-3d, f can be compared with similarly knobby surfaces described from microbial mats in Texas. In the Texas examples, the knobby surfaces were found in a vertical zone above most tides, and they were attributed to microbial coating of sand that had accumulated around grass roots (Bose and Chafetz, 2012). In the Anegada examples in Fig.…”

Biosignature Preservation and Detection in Mars Analog Environments

“…Microbially induced sedimentary structures are preserved and exceptionally well-studied in the modern Pilot Valley Basin, Utah, and on geologic timescales in the ancient Strelley Pool Chert stromatolites and Dresser Formation microbialites of the Archean-aged Pilbara Craton (Van Kranendonk et al 2003 ; Allwood, et al, 2006 ; Noffke et al, 2013 ; Russell et al, 2014 ; Lynch et al, 2015 ; Westall et al, 2015b ; Lindsay et al, 2017 ). Likewise, microbially induced sedimentary structures can be found in most aquatic environments, both marine and lacustrine, including tidal flats, lagoons, riverbeds, dunes, and sabkhas (see Noffke et al, 2001 ; Bose and Chafetz, 2012 ; Noffke et al, 2013 , and references therein).…”

Processes of MISS-formation in a modern siliciclastic tidal flat, Patagonia (Argentina)

“…The different gaseous compounds such as O 2 , CO 2 and CH 4 are produced by microbial activity, photosynthesis and decomposition (Gerdes et al, 2000, Schieber, 2004. Gas domes were described in several tidal flats; in turn Bose and Chafetz (2011) found them occurring in the upper supratidal areas in a microtidal regime. Also, Gerdes (2007) and Noffke et al ( , 2010 described the presence of gas domes in different environments, not restricted to arid areas but occur on tidal flats of temperate humid climate zone and also subaquatically.…”

“…Noffke (2010) associated gas domes with the normal high water line due to the pushing of gases by the rising tide. Bose and Chafetz (2011) related the formation of erosional pockets, mat chips, rippedup mats, and eroded boundaries of mats to physical destruction process indicating a high energy environmental condition for their development in a micro tidal environment. Also, Noffke (1999) described erosional pockets and remnants in tidal flats of Mellum Island where the sandy surface of the pockets were not overgrown by microbial mats exposing ripple marks.…”
