“…This present-day pattern is consistent with that shown by the literature review and the case study presented here, because modern and fossil agglutinated microbialites occur only in shallow-marine environments, contrasting with the many non-marine microbialites that do not accrete mainly by 'trapping and binding', despite occurring in grainy settings (e.g. Kalkowsky, 1908;Cole and Picard, 1978;Neuhauser et al, 1987;Camoin et al, 1997;Paul and Peryt, 2000;Seard et al, 2013;Chidsey et al, 2015;Bouton et al, 2016b;Suarez-Gonzalez et al, 2016a, 2016b; Table 3). Furthermore, microbialite EPS form not only the sticky surface to which grains adhere, but they are also, and mainly, the locus of mineral precipitation (Burne and Moore, 1987;Dupraz et al, 2009;Riding, 2011a).…”

“…Similarly, many other fossil and modern examples of microbialites that developed in grainy and commonly agitated environments do not show significant grains trapped within their microfabrics (e.g. Kalkowsky, 1908;Cole and Picard, 1978;Neuhauser et al, 1987;Camoin et al, 1997;Paul and Peryt, 2000;Seard et al, 2013;Chidsey et al, 2015;Bouton et al, 2016b). In fact, only a few examples associated with shallow-marine settings, and especially with tidal influence, do (Tables 1, 2).…”

Trapping and binding of allochthonous grains by benthic microbial communities has been considered a fundamental process of microbialite accretion since its discovery in popular shallow-marine modern examples (Bahamas and Shark Bay). However, agglutinated textures are rare in fossil microbialites and, thus, the role of trapping and binding has been debated in the last four decades. Recently, renewed attention on this subject has produced new findings of fossil agglutinated microbialites (those mainly formed by 'trapping and binding' and analogous to modern examples), but they are still few and geologically recent (post-Paleozoic) when compared to the 3.5 Gyr long record of microbialites. In order to better understand this discrepancy between modern and fossil examples, an extensive literature review is presented here, providing the first thorough database of agglutinated microbialites, which shows that all of them are formed in shallow-marine environments and most under tidal influence. In addition, a Lower Cretaceous example is described, including very diverse microbialites, each of them formed in a particular paleoenvironment. Some of these microbialites developed in grainy settings, but only those formed in marginal-marine tide-influenced environments accreted mainly by trapping and binding the surrounding grains, being analogous of modern agglutinated microbialites, and matching the environmental pattern observed in the literature database. The combination of the literature review with the case study allows to discuss the factors that control and enhance 'trapping and binding': a) occurrence of grains in the microbialite environment; b) frequent currents that mobilize the grains and supply them onto the microbialite surface; c) high concentration and diversity of electrolytes in the water to increase the adhesiveness of the extracellular polymeric substances (EPS) of the microbialite surface; and d) a CaCO 3 saturation state not high enough to promote early and strong carbonate precipitation within EPS, which would eventually decrease its availability to adhere grains. Therefore, this review shows that the keys to solve the 'trapping and binding' debate may be environmental, because the conjuction of these hydrodynamic and hydrochemical parameters is preferentially achieved in shallow-marine settings and especially in those influenced by tides, at least since Mesozoic times. This explains the limited environmental and stratigraphic distribution of microbialites mainly formed by 'trapping and binding', and opens new ways to look, geologically and microbiologically, at this process, so often cited and yet so rare.

The Piceance Creek Basin in northwestern Colorado contains extensive oil shale deposits that produce natural gas and which could potentially yield ~1.5 trillion barrels of shale oil. However, much of the oil shale lies at depths too great for traditional mining practices and various innovative approaches for in situ conversion of kerogen to oil have been proposed. A firm understanding of the iii ACKNOWLEDGEMENTS I would like to thank my advisor, Ben Perkins, for his support, guidance, and patience over the duration of this process. Thanks to my committee members, Carl Palmer, John Bershaw, and Max Rudolph for their thoughtful comments and insights. I would also like to thank my family and friends who have been endlessly patient and supportive during this process. I could not have done this without them.
