According to microfacies and sedimentological analyses the bathymetric position of the Lithocodium/ Bacinella banks ranges from deeper subtidal to shaUowest subtidal/intertidal conditions. The maximum depth is related to the photic zone, which ,itself is controled by the amount of muddy suspension. The upper bathymetric limit is mechanically defin'ed and corresponds to increased depositional energy (i.e. waves and tidal currents). Together with other algae and microbes Lithocodium/ Bacinella is a major constituent of thrombolitic mud mounds (Gandara mound). In the context of mud mound genesis the functional role of Lithocodium/ Bacinella includes baffling and binding, the production of micrite via the calcification inside of mucilagenous sheaths, and via intensive boring activities upon and inside of skeletal hardparts. The mass occurrence of Lithocodium/ Bacinella with associated algae and microbes may be explained by a longer ranging eutrophism of the environment or by shifts in seawater carbonate alkalinity."],["dc.format.mimetype","application/pdf"],["dc.identifier.ppn","50213349x"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/2172"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60942"],["dc.language.iso","de"],["dc.notes.intern","Migrated from goescholar"],["dc.publisher","Fachber.

Factors such as increased alkalinity ,oligotrophy, and reduced allochthonous deposition are of major importance. Thrombolitic microbialites are interpreted as biologically induced and therefore calcified in isotopic equilibrium with the surrounding sea water.

Mineralization related to non-living organic substrates results in autochthonous micrite production (‘automicrites’). ‘Automicrites’ are the main constructive element of Lower Cretaceous (Albian) carbonate mud mounds in northern Spain. These slope mud mounds occur within transgressive and early highstand system tracts encompassing several macrobenthic ecological zones. They are clearly separated from the biocalcifying carbonate factory (Urgonian carbonate platforms), in both space and time. Within these build-ups, most ‘automicrites’ were initially indurated and accreted to form a medium-relief growth framework. ‘Automicrites’ have a uniform, presumably high-Mg-calcite precursor mineralogy. They show an inorganic stable-isotope signature (∂13C around +3·3‰) within the range of early marine cements, and skeletal compounds lacking major vital effects. Epifluorescence microscopy shows that they have facies-specific fluorescence, which is similar to skeletal compounds of Acanthochaetetes, but clearly different from allomicritic sediment and cements, which are mostly non-fluorescent. The EDTA-soluble intracrystalline organic fraction (SIOF) of Albian automicrites shows an amino acid spectrum that is similar to shallow subsurface samples from their modern counterparts. Gel electrophoresis of the SIOF demonstrates an exclusively acidic character, and a mean molecular size range between 20 and 30 kDa. Experiments in vitro (inhibition tests) indicate that the SIOF has a significant Ca2+-binding capacity. Fluorescence and chemical characteristics of SIOF point to a main substance class, such as humic and fulvic acids, compounds that form from pristine organic matter during early diagenesis. Biomarker analyses provide evidence for the crucial role of biodegradation by heterotrophic microorganisms, but no biomarker for cyanobacteria has been found. Primary sources of organic material should have been manifold, including major contributions by metazoans such as sponges. It is concluded that many carbonate mud mounds are essentially organomineralic in origin and that the resulting fabric of polygenetic muds (‘polymuds’) may represent ancestral metazoan reef ecosystems, which possibly originated during the Neoproterozoic."],["dc.identifier.doi","10.1046/j.1365-3091.1999.00255.x"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15167"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.eissn","0037-0746"],["dc.relation.eissn","1365-3091"],["dc.title","Petrology of Lower Cretaceous carbonate mud mounds (Albian, N.
