Die mikrofaziell-sedimentologische Analyse des Profils crgibt für die Lithocodium/ Bacinella Bänke eine bathymetrische Position vom tieferen Subtidal bis flachsten Subtidal/lntertidal. Die maximale Tiefenposition ist an die photische Zone gebunden, die wiederum durch das Ausmaß toniger Suspensionen beeinflußt wird. Die bathymetrische Obergrenze ist mechanisch kontrolliert (z.B. WeUenenergie, Tidenströme). Lithocodium/Bacinella ist zusammen mit anderen Algen/Mikroben ein charakteristischer Bestandteil thrombolithischer Mud Mounds (z.B. Gandara Mound). Die funktionelle Rolle von Lithocodium/Bacinella bei der Mud Mound Genese umfaßt Baffling und Binding, AutomikritProduktion durch Kalzifizierung innerhalb organischer Schleimhüllen und eine Mikritproduktion über intensive Bohraktivitäten an eingelagerten karbonatischen Hartteilen. Das massenhafte Auftreten von Lithocodillm/ Bacinella und diversen Algen/Mikroben kann mit einer längerfristigen Eutrophierung des Lebensraumes oder mit Schwankungen der Karbonat-Alkalinät des Meerwassers erklärt werden."],["dc.description.abstract","A section including Lithocodium/ Bacinella boundstones with a thickness of up to 8 m is reported from the Lower /Middle Albian of northern Spain. 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. Corresponding with shallowing upward cycles, microbial mats which produce stromatolitic peloidal crusts become more important. Different biomarkers are introduced for the first time extracted and analyzed from spongiolitic limes tones ofLower Kimmeridgian age from Southern Germany."],["dc.format.mimetype","application/pdf"],["dc.identifier.doi","10.1007/BF02536916"],["dc.identifier.ppn","502136790"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/2191"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/91820"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.relation.orgunit","Fakultät für Geowissenschaften und Geographie"],["dc.rights","Goescholar"],["dc.rights.access","openAccess"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","Paläontologie: Allgemeines"],["dc.subject.ddc","560"],["dc.title","Microbial carbonate crusts - a key to the environmental analysis of fossil spongiolites?"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
