The '''Calcaires du Bou Dahar''' (also known as '''Djebel Bou Dahar Paleoshoal''', '''Djebel Bou Dahar''', '''Calcaires du Bou Dahar Formation''', or '''Bou Dahar Formation''') is a geological [[Formation (geology)|formation]] or a sequence of formations of Late [[Sinemurian]] to [[Pliensbachian]]-[[Toarcian]] boundary ([[Early Jurassic]]) age in [[Bni Tadjite]], the [[High Atlas|Central High Atlas]], [[Morocco]]. This unit represents an excepcional record of an evolving [[reef]] complex (mountain laterals),  platform slopes (Steep slopes between 20° and 35° on various sides) and a emerged [[shoal]] (nearly horizontal limestone layers on the top flat Bou Dahar plateau) developed inside a [[carbonate platform]], recording the evolutionary cycles of this environment with notorious precision, also yielding what is considered one of the greatest/most diverse marine biotas of the entire Jurassic [[Tethys Ocean]].<ref name=":23">{{Cite journal |last1=Elmi |first1=S. |last2=Amhoud |first2=H. |last3=Boutakiout |first3=M. |last4=Benshili |first4=K. |date=1999 |title=Cadre biostratigraphique et environnemental de l'evolution du paleorelief du Jebel Bou Dahar (Haut-Atlas oriental, Maroc) au cours du Jurassique inferieur et moyen. |url=https://pubs.geoscienceworld.org/sgf/bsgf/article-abstract/170/5/619/88177/Cadre-biostratigraphique-et-environnemental-de-l |journal=Bulletin de la Société Géologique de France |volume=170 |issue=5 |pages=619–628}}</ref> The Bou Dahar carbonate platform shoal stands prominently and structurally above surrounding plains, spanning 35-40 km in length and 4-15 km in width, with a relief of 100-450 m.

[[File:Jbel Bou Dahar sequences.png|thumb|upright=1.35|Succession of depositional sequences in the Bou Dahar platform]]
The Bou Dahar platform is a well-preserved example of carbonate platform development within a tectonically active rift-basin environment. This region formed as part of the Jurassic [[High Atlas]] seaway, where tectonic activity shaped the basin, with influences from rifting, faulting, and transtensional forces.<ref name=":4">{{Cite journal |last1=Kenter |first1=Jeroen A.M. |last2=Campbell |first2=A.Ewan |date=1991 |title=Sedimentation on a Lower Jurassic carbonate platform flank: geometry, sediment fabric and related depositional structures (Djebel Bou Dahar, High Atlas, Morocco) |url=http://dx.doi.org/10.1016/0037-0738(91)90121-s |journal=Sedimentary Geology |volume=72 |issue=1–2 |pages=1–34 |doi=10.1016/0037-0738(91)90121-s |bibcode=1991SedG...72....1K |issn=0037-0738}}</ref> Early studies mapped the area’s Jurassic marine environments, with carbonate platform margins situated alongside deeper basin limestones. This platform records two primary periods of shallow-water carbonate growth: one during the Lower to Middle Liassic (Sinemurian to [[Domerian]]) and a subsequent phase spanning the Upper Liassic to Lower Dogger ([[Aalenian]] to [[Bajocian]]). However, only the earlier phase is preserved in Djebel Bou Dahar.<ref>{{Cite journal |last=Paul Crevello |date=1990 |title=Tectonic and Eustatic Controls on Carbonate Platforms of the Jurassic High Atlas Rift of Morocco: ABSTRACT |url=http://dx.doi.org/10.1306/44b4af32-170a-11d7-8645000102c1865d |journal=AAPG Bulletin |volume=74 |doi=10.1306/44b4af32-170a-11d7-8645000102c1865d |issn=0149-1423}}</ref>  This phase was abruptly interrupted at the Domerian-Toarcian transition, marked by the onlap of Toarcian shales and Aalenian lime mudstones over the platform, signaling a shift to deeper marine conditions.<ref name=":4" />

The seismic modeling of Bou Dahar platform highlighted large-scale structures, such as the platform's form and the boundary marking its submergence, across various frequencies and modeling approaches. Lower-frequency wavelets emphasized truncation of layers and outward shifts in onlap points.<ref name=":1" /> In contrast, internal platform [[facies]] zones were less distinct at frequencies below 50 Hz, but with a geometry still discernible through disturbances in reflections, especially near the lower boundaries, with image-ray migration models proving more responsive to these subtle variations even at lower frequencies. Seismic contrast, driven by differences in acoustic impedance, tends to decline with deeper burial and subsequent diagenesis, with peak resolution typically present at initial deposition stages before significant burial effects.<ref name=":1" />

Sequences I-II overlie CAMP basalts, spanning over 126 & 150 meters, marked by a dolomite-rich boundary featuring fenestral and stromatolitic structures, which indicate transgressive-regressive (T-R) cycles. Dominance of subtidal carbonates suggests extensive shallow marine conditions across the platform.<ref name=":8">{{Cite journal |last1=Verwer |first1=K. |last2=Merino-Tome |first2=O. |last3=Kenter |first3=J.

Sequence III developed as a low-relief carbonate platform and varies in slope angle between northern and southern margins, with thickness peaking in northeastern synclines at around 100 meters. Thinning toward the center, it comprises laterally continuous skeletal and packstone deposits interspersed with sponge mounds, mirroring the [[Foum Zidet Formation]].<ref name=":5" /><ref name=":8" /><ref name=":10" />

Sequence IV with a wedge-shaped geometry, reveals steep slopes and retrogradational stacking, indicating subaerial exposure at its base with ammonite-rich wackestone beds.<ref name=":8" /> This sequence thickens at the southern margin, where coral and sponge boundstones, extending to 140 meters, transition into grainstone and packstone accumulations along the slope. The eastern platform edge hosts cross-bedded grainstone layers, lacking intertidal deposits, characteristic of open-marine conditions.<ref name=":5" /><ref name=":8" /><ref name=":10" />

Sequence V, along Sequences IV to VI correlate with the [[Aganane Formation]] and [[Ouchbis Formation|Ouchbis Formations]], being a progradational wedge, is thickest along the platform's southern and eastern edges, forming a concave-up clinoform structure, reaching 50-70 meters in height and indicating alternating subtidal and intertidal lithofacies and evidence of exposure events. Moving basinward, finer basinal sediments with green marls and peloidal wackestones emerge, suggesting periodic sediment starvation during the Early [[Pliensbachian]].<ref name=":5" /><ref name=":8" /><ref name=":10" />

The final sequence, Sequence VI, fills the last stage of platform development with angular unconformity over older layers and CAMP basalts.<ref name=":8" /> This sequence encompasses varied facies belts surrounding a central paleo-high with subtidal and intertidal deposits, coated-grain bars, and coastal-plain sediments like red shales and calcretes. Clinoforms along the lower slope show a concave-up profile that flattens basinward, with deposits consolidating into a fan along the southern margin, evidence of sediment redistribution likely from mass wasting.<ref name=":5" /><ref name=":10" />

The paleoenvironment of Bou Dahar is characterized by a dynamic evolution through distinct stages: pre-drowning, drowning, and post-drowning, each marked by specific sedimentological and ecological changes that reflect shifts in energy conditions and depositional environments.<ref name=":10" /><ref name=":13">{{Cite journal |last1=Elmi |first1=S. |last2=Amhoud |first2=H. |last3=Boutakiout |first3=M. |last4=Benshili |first4=K. |date=1999 |title=Biostratigraphic and environmental data on the history of Jebel Bou Dahar (eastern High Atlas, Morocco) palaeo-shoal during the early and middle Jurassic Cadre biostratigraphique et environmental de l'evolution du paleorelief du Jebel Bou Dahar (Haut-Atlas oriental, Maroc) au cours du Jurassique inferieur et moyen |url=https://rmp-tiers.net/paper/e5814725313440e1bec8117532d0866c01096558af5b11d5aae63415da4c3a59/ |journal=Bulletin de la Société Géologique de France |volume=170 |issue=5 |pages=619–628}}</ref>

During the pre-drowning phase, the carbonate platform was dominated by tranquil lagoonal settings, indicative of low-energy environments. These conditions fostered the accumulation of microsparite carbonates, which are essential in maintaining the stable conditions found in [[lagoons]].<ref name=":10" />  The presence of bioturbation, mud cracks, and tidal flats illustrates the periodic exposure of the substrate, suggesting a complex interplay of biogenic and abiogenic processes. The platform margin transitioned into coarser zones where higher-energy environments were characterized by sorted carbonate sands and natural barriers. This transitional buffer from the lagoon to slope facilitated the formation of intertidal mounds, which played a crucial role in the sediment dynamics of the region.<ref name=":10" />

As the platform underwent drowning, it shifted towards high-energy conditions. Sediments from this phase exhibited dense [[biosparite]]s with significant skeletal deposits, indicating heightened wave action and the erosion of previously accumulated lagoonal deposits. The transition to these high-energy environments underscores a significant change in the depositional dynamics, where sediment transport was dominated by stronger currents. The emergence of tepee structures in the platform carbonates reflects this period of increased energy.<ref name=":4" /> Formed from early [[lithification]] and sediment infill in intertidal zones, these structures were characterized by cracks filled with fine sediments and stromatolitic algae, highlighting rapid infilling processes shortly after deposition. Unlike their recent counterparts in the [[Persian Gulf]], the Moroccan tepees developed in fully lithified rocks, shaped by thermal expansion and contraction driven by temperature variations in intertidal settings.<ref>{{Cite journal |last1=Burri |first1=P. |last2=du Dresnay |first2=R. |last3=Wagner |first3=C.W. |date=1973 |title=Tepee structures and associated diagenetic features in intertidal carbonate sands (lower Jurassic, Morocco) |url=http://dx.doi.org/10.1016/0037-0738(73)90046-8 |journal=Sedimentary Geology |volume=9 |issue=3 |pages=221–228 |doi=10.1016/0037-0738(73)90046-8 |bibcode=1973SedG....9..221B |issn=0037-0738}}</ref>

Microscopic examination of the sediments reveals a rich diversity of biogenic and non-biogenic components, categorized into nine distinct microfacies types.<ref name=":4" /> These include laminated pelmicrites, biopelsparites, and various intraclasts and bioclasts, showcasing the complex interplay of environmental factors influencing sediment composition. Foraminifers along with corals, indicate thriving marine ecosystems during the deposition of Bou Dahar.<ref name=":13" /> The various microfacies illustrate shifts in sedimentation dynamics, with microfacies types reflecting different depositional environments-from tranquil lagoonal settings to more energetic reef environments.<ref name=":7">{{Cite journal |last1=Scheibner |first1=Christian |last2=Reijmer |first2=J.

Local carbonate factories present a unique contrast with other coeval units in the Tethys, with [[siliceous sponge]] microbial boundstone mounds, which were more prevalent in Middle and [[Upper Jurassic]] systems. Despite their earlier emergence, these mounds show similarities to younger Jurassic formations in texture and biological components. They thrived in deep-water environments, particularly in areas that experienced low detrital input.<ref name=":14">{{Citation |last1=della Porta |first1=Giovanna |title=Lower Jurassic Microbial and Skeletal Carbonate Factories and Platform Geometry (Djebel Bou Dahar, High Atlas, Morocco) |date=2014-09-01 |work=Deposits, Architecture, and Controls of Carbonate Margin, Slope, and Basinal Settings |pages=237–263 |url=http://dx.doi.org/10.2110/sepmsp.105.01 |access-date=2024-10-29 |publisher=SEPM (Society for Sedimentary Geology) |isbn=978-1-56576-323-4 |last2=Merino-Tomé |first2=Oscar |last3=Kenter |first3=Jeroen A.M. |last4=Verwer |first4=Klaas|doi=10.2110/sepmsp.105.01 }}</ref> Siliceous sponge mounds record distinct rare earth element  and yttrium patterns among carbonate components, indicating that Early Jurassic seawater resembled modern distributions.
