“…Evidence for subaerial exposure during sedimentation has been interpreted by some authors as indicating deposition during lowstands. This view might initially seem to be strengthened by the occurrence of palustrine facies within palaeokarst cavities or draping karstified relief, as in the Miocene of South Australia (Miller, 2012), the Lower Cretaceous of Croatia (Dini et al, 1998) and the late Visean of the Moscow Basin (Alekseeva et al, 2016; Kabanov et al, 2016). However, the present‐day context of Caribbean freshwater carbonate factories suggests deposition later within eustatic cycles, when transgression causes groundwater levels to rise through the karst of caves, cenotes and sinkholes.…”

“…Examples are recorded in the Tournaisian–Visean of western Europe (Muchez & Viaene, 1987; Searl, 1988; Vanstone, 1991; Wright et al, 1997) and the late Visean of Kentucky (Barnett et al, 2013) and the Moscow Basin (Alekseeva et al, 2016; Kabanov et al, 2016). While many of these examples are stratigraphically localised, extensive and long‐lived brackish dolomitic coastal wetlands with marshes and lakes, some of which became evaporitic, have been described from Tournaisian greenhouse settings from the Ballagan Formation in South‐East Scotland and North‐East England (Bennett et al, 2021, and examples therein).…”

The Depositional Record

The dynamic inter‐relationships between marine and freshwater carbonate depositional environments are illustrated in the Sian Ka'an Wetlands, a 5 280 km2 complex of groundwater‐fed freshwater marshes, lakes and brackish coastal lagoons in the South‐East Yucatán Peninsula (Mexico). The Yucatán Platform was subaerially emergent and extensively karstified during the last glacial maximum at 18, 000 yr bp. The Late Holocene transgression has caused progressive reflooding of the continental margin, backstepping of the MesoAmerican Reef and encroachment of coastal environments into the platform interior as rising groundwaters flood an interconnected cave and sinkhole system and feed seasonal marshes above. The Sian Ka'an Wetlands form a vast palustrine carbonate factory which is directly juxtaposed and dynamically linked with the marine carbonate factory to seaward. Continuing sea‐level rise has caused synchronous landward migration of marginal marine and freshwater environments as beach barriers were breached and palustrine sloughs flooded to form marginal marine seagrass lagoons. The Rio Hondo Fault conditions fluid inflow while the sub‐environments of the Sian Ka'an Wetlands reflect tectonic controls on microtopography and hydroperiod. Modern analogues for the Sian Ka'an Wetlands include the Florida Everglades, formed during transgression of the Florida Platform, and relict marsh environments preserved on leeward shores of Andros, Abaco and other Bahama islands. A wide range of ancient examples deposited in coastal and continental interior settings similarly reflect seasonal aquifer rise in response to marine transgression and/or onlap of late‐stage basin fill onto a karstified pediment. Freshwater palustrine carbonate factories on carbonate platforms are transient deposystems, controlled by subtle water depth, climate, vegetation and hydrological factors while being critically sensitive to sea‐level changes and tectonics. The preservation potential of palustrine carbonates may be relatively low in coastal settings due to erosion or shallow marine overprinting, while greater further inland where marine flooding is rarer and in tectonically subsident continental interior basins where accommodation space is continuously created.

A new miospore genus, Maiaspora, is described from the upper Visean (middle Mississippian) of the southern wing of Moscow Syneclise (European Russia). Applying a combination of methods (optical light microscopy (LM), scanning‐electron microscopy, confocal laser microscopy (CLSM) and image analysis) to the same individual miospore specimens revealed a remarkable sculptural type for which we propose the new term ‘metareticuloid’. Metareticuloid sculpture is defined as a complex arrangement of muri with apiculate elements, polygonal lumina and circular scrobiculae at the base of the lumina. The discovery of fossil spores with metareticuloid sculpture allows the recognition of clear morphological differences between microreticulate and foveolate sculptures, which palynologists have historically had difficulty in separating. Virtual cross‐sections provided by CLSM show that miospores with metareticuloid sculpture display perfectly preserved, funnel‐shaped tunnels (like a gallery of cave stalactites) in the deep exospore. In contrast, miospores with microreticulate or reticulate and partly vermiculate sculpture lack such vertical tunnels (termed scrobiculae). The morphology of Maiaspora gen. nov. is considered in comparison with Microreticulatisporites (Knox non sensu Potonié & Kremp) Bhardwaj emended Oshurkova, Pseudoreticulatispora Bharadwaj & Srivastava emended Price & Foster, Vadaszisporites (Deák & Combaz) emended Juhász, Foveosporites Balme, Foveotriletes van der Hammen ex Potonié, Garotriletes Singh & Singh, Assamiasporites Mehrota & Sah, and Margotriletes Mehrota & Sah. The morphological conceptions of Microreticulatisporites and Foveotriletes are reinterpreted by numerical typification. The adaptative significance of metareticuloid sculpture is discussed in relation to modern and fossil spores, and in terms of harmomegathic mechanisms of angiosperm pollen.

“…Much research has also been done on the significance of pedogenesis and karstification during periods of exposure and flooding of Carboniferous carbonate platforms (Alekseeva et al, 2016;Davies, 1991;Vanstone, 1996Vanstone, , 1998Wright et al, 1997). This paper focuses on the microfacies and depositional environment of the F I G U R E 1 (a) Brigantian palaeogeography of the Derbyshire carbonate platform during deposition of the Eyam Limestone Formation (from Gutteridge, 1987) showing the intrashelf basin; reactivated structures that influenced sedimentation include the Longstone Edge Monocline (LEM) the Taddington-Bakewell Anticline (TBA), Edensor Anticline (EA) and the Bonsall Fault (BF).…”

Lacustrine and palustrine carbonates in a Brigantian (late Dinantian) intrashelf basin in the Derbyshire carbonate platform

The Brigantian (late Dinantian) Headstone Laminite provides a record of freshwater carbonate deposition in an intrashelf basin when the surrounding Derbyshire carbonate platform was emergent. The laminated grainstone/carbonate mudstone facies contains calcified plant material, peloids, ostracods and lenses of calcite tufa deposited in a lake margin and sublittoral part of a freshwater lake in a humid palaeoclimate. Precipitation of tufa may have taken place along water courses or resurgences fed by meteoric run‐off and seepage from the karsted carbonate platform. The fenestral carbonate mudstone with calcrete and fenestrae represent deposition in well‐drained parts of the lake margin. A shift to more arid conditions is represented by the laminated dolomudstone facies with an allochem assemblage of calcified plants and micropeloidal dolomicrospar grains and occasional alginite in restricted a lake basin setting. Gypsum crystals and desiccation curls are also present in evaporitic lake margin settings. A return to more humid conditions is indicated by deposition of the laminated grainstone/carbonate mudstone facies with organic‐rich mudstone with thin coal seams and carbonized roots deposited in a poorly drained lake margin setting. This may be a reflection of a gradual transgression after emergence. The eastern margin of the intrashelf basin may have been formed by the Edensor Anticline; however, it is not known if a further complex of lacustrine, palustrine and lagoonal facies was present to the east. Deposition of graded beds containing lithoclasts derived from lacustrine facies were associated with slumping generated by reactivation of structures controlling the intrashelf basin margins.
