... that these deep mounds are biohermal in nature and constructed in situ by the subsea lithification of successive layers of trapped sediment and deposited skeletal debris. The term “lithoherm” is proposed to describe the mounds. These and the hardgrounds between them indicate that subsea lithification aids...

... (brachiopods, bivalves, and echinoderms). Marl-limestone rhythmites represent muddy bottoms colonized by scarce endobenthos (bivalves and irregular echinoids). However, the occurrence of patchy sponge bioherms provided a favorable substrate for epibionts and microbial lithoherms (microbialites). The record...

... to subtidal environment of deposition prior to the onset of deeper-water conditions. Upward in the section, this sequence passes fairly abruptly into deeper-water lithoherms, massive micritic buildups that lack the coral and skeletal framework common in shoal-water reefs marginal to the trough. The lithoherms...

... the early highstand. Three commonly used depositional models, abbreviated as the lithoherm model, the baffling model, and the microbial model, are evaluated with respect to the Fort Payne buildups. None of the models is deemed adequate to explain all of the features of the buildups. Rather, a combination...

... structures are present. Deep-water biohermal buildups (lithoherms) and a variety of porous, coarse-grained gravity-flow deposits have been found along the deep bank margins in the northern Bahamas interfingering with deep-basin chalks. Structures such as diapirs, faults, basement highs, and erosional...

In some cases, the high resolution allows for recognition of prograding sand waves (lower left corner). (D) Examples of mound-shaped lithoherms at the bottom of the Santaren
