    Description / Table of Contents: Der Einfluß metamorpher und hydrothermaler Überprägung auf primär angelegte magmatische und sedimentäre Schwefel-Isotopensignaturen wurden am Beispiel des 4000 m mächtigen Kristallinprofils der KTB-Vorbohrung systematisch untersucht und dargestellt. Der Einfluß der polymetamorphen Überprägung erwies sich dabei als so gering, daß die Variation der S-Isotopenverhältnisse teilweise im Rahmen prämetamorpher Prozesse interpretiert werden kann. Um Hinweise auf die Natur der Bildungs- und Isotopen-Fraktionierungsmechanismen schwefelführender Minerale zu erhalten, wurde ein chemisches Trennverfahren erarbeitet und angewendet. Die Schwefelisotopenuntersuchungen werden durch einen Beitrag zur Spurenelementgeochemie des Pyrits ergänzt. Aufgrund der Auswertung der Meßdaten mittels multivariater Methoden konnten die Pyrite in verschiedene genetische Typen klassifiziert und Beziehungen zur Isotopensignatur des Schwefels identifiziert werden.

    In:  Supplement to: Abramovich, Sigal; Keller, Gerta; Stüben, Doris; Berner, Zsolt (2003): Characterization of late Campanian and Maastrichtian planktonic foraminiferal depth habitats and vital activities based on stable isotopes. Palaeogeography, Palaeoclimatology, Palaeoecology, 202(1-2), 1-29, https://doi.org/10.1016/S0031-0182(03)00572-8

    Description: Depth habitats of 56 late Cretaceous planktonic foraminiferal species from cool and warm climate modes were determined based on stable isotope analyses of deep-sea samples from the equatorial Pacific DSDP Sites 577A and 463, and South Atlantic DSDP Site 525A. The following conclusions can be reached: Planoglobulina multicamerata (De Klasz) and Heterohelix rajagopalani (Govindan) occupied the deepest plankton habitats, followed by Abathomphalus mayaroensis (Bolli), Globotruncanella havanensis (Voorwijk), Gublerina cuvillieri Kikoine, and Laeviheterohelix glabrans (Cushman) also at subthermocline depth. Most keeled globotruncanids, and possibly Globigerinelliodes and Racemiguembelina species, lived at or within the thermocline layer. Heterohelix globulosa (Ehrenberg) and Rugoglobigerina, Pseudotextularia and Planoglobulina occupied the subsurface depth of the mixed layer, and Pseudoguembelina species inhabited the surface mixed layer. However, depth ranking of some species varied depending on warm or cool climate modes, and late Campanian or Maastrichtian age. For example, most keeled globotruncanids occupied similar shallow subsurface habitats as Rugoglobigerina during the warm late Campanian, but occupied the deeper thermocline layer during cool climatic intervals. Two distinct types of „vital effect“ mechanisms reflecting photosymbiosis and respiration effects can be recognized by the exceptional delta13C signals of some species. (1) Photosymbiosis is implied by the repetitive pattern of relatively enriched delta13C values of Racemiguembelina (strongest), Planoglobulina, Rosita and Rugoglobigerina species, Pseudoguembelina excolata (weakest). (2) Enriched respiration 12C products are recognized in A. mayaroensis, Gublerina acuta De Klasz, and Heterohelix planata (Cushman). Isotopic trends between samples suggest that photosymbiotic activities varied between localities or during different climate modes, and may have ceased under certain environmental conditions. The appearance of most photosymbiotic species in the late Maastrichtian suggests oligotrophic conditions associated with increased water-mass stratification.
