Microbial origin of travertine fabrics—two examples from Southern Germany (Pleistocene stuttgart travertines and miocene riedöschingen Travertine)

  author={Christoph Koban and G{\"u}nter Schweigert},
SummaryIn Southern Germany, two examples of travertines of different age and depositional morphology were examined in detail. Travertines are laminated carbonate rocks formed by precipitation from mineral and/or thermal waters. They include characteristic facies types, such as bushy layers (‘shrubs’) referred to calcification of branching microbes (‘Dichothrix’-morphotype), laminar microbial mats, peloidal layers, and gas bubble layers formed within the sediment. In travertines, microbial… 
Modern freshwater microbial carbonates: thePhormidium stromatolites (tufa-travertine) of southeastern Burgundy (Paris Basin, France)
SummaryThe relationships of microstructure and vegetal remains, obtained by decalcification, were studied in Modern tufa from Burgundy, in order to try to link a given species with a particular
Holocene microbial tufas: Orissa State, India
Holocene microbial tufas, dominantly of stromatolitic crusts, have been formed in a tropical setting of Orissa State, India. These occur as stratified crusts in various dispositions and are also
Decoding tufa and travertine (fresh water carbonates) in the sedimentary record: The state of the art
Traditionally, fresh water carbonate research has focused on the sedimentology and palaeontology of ancient lacustrine deposits. Lithofacies in such low‐energy deposits are typically fine‐grained,
Microbial crusts of the late jurassic: Composition, palaeoecological significance and importance in reef construction
SummaryUpper Jurassic reefs contain variable amounts of calcareous microbial crusts. In examples from Portugal, Spain and southern Germany they occur within coral biostromes and bioherms, mixed

SummaryThe petrographic investigation of the Miocene Rieslake-carbonates gave rise to a modifiedDunham-scheme for classifying non-marine carbonates. If the fabric is not exclusively the result of
Evolution of Pleistocene travertine depositional system from terraced slope to fissure-ridge in a mixed travertine-alluvial succession (Jebel El Mida, Gafsa, southern Tunisia)
The Quaternary stratigraphic record of Jebel El Mida, composed of continental deposits, is a useful example of concomitant travertines and alluvial deposition in an extensional setting. Travertine
Travertine: Distinctive depositional fabrics of carbonates from thermal spring systems
The terrestrial limestones forming at the emergence of thermal springs show a variety of unusual depositional facies. The specific lithological and petrological features of these deposits have few
Petrography and geochemistry of Quaternary travertines in the Ab-e Ask region, Mazandaran Province- Iran
The travertine deposit springs are located on the southeast of the Damavand Volcano, 85 km northeast of Tehran Province. The deposits of these springs mainly outcropped with cascade, hill, conical,
Upper Jurassic travertine at El Macanudo, Argentine Patagonia: a fossil geothermal field modified by hydrothermal silicification and acid overprinting
Abstract The Deseado Massif hosts numerous Late Jurassic (150 Ma) fossil geothermal systems related to an extensive volcanic event developed in a diffuse extensional back-arc setting. Detailed

Origin and diagenesis of lacustrine algal bioherms at the margin of the Ries crater, Upper Miocene, southern Germany
The marginal carbonate facies of the Miocene Ries meteorite crater lake in southern Germany contain bioherms up to 7 m high and 15 m across built by the green alga Cladophorites. The algae were
Aragonite laminae in hot water travertine crusts, Rapolano Terme, Italy
Small (5–30 μm) aggregates of aragonite needles occur in calcite crystal crusts of present day hot water slope travertines at Rapolano Terme in Tuscany, Italy. The aggregates are mainly concentrated
Diagenesis of Laminated Travertine Crusts, Arbuckle Mountains, Oklahoma
ABSTRACT Waterfall travertine deposits in the Arbuckle Mountains of Oklahoma contain laminated, coarsely crystalline, neomorphic crusts which retain virtually no evidence of their organic origin. The
Travertines in the northern Hula Valley, Israel
This study describes the field and petrographic relationships of a widespread deposit of Pleistocene travertines in the northern Hula Valley, northern Israel. The travertines interfinger with
Bizarre forms of Depositional and Diagenetic Calcite in Hot-Spring Travertines, Central Italy
Travertines of central Italy have been deposited froni warm: fresh-water springs very rich in H2S. Probably as a result of this, the carbonate sediments are largely constructed by bacteria instead of
Salina-margin tepees, pisoliths, and aragonite cements, Lake MacLeod, Western Australia: Their significance in interpreting ancient analogs
Tepee structures, banded aragonite cements, and pisoliths are currently forming in Lake MacLeod, a carbonate-evaporite salina in Western Australia. Although Lake MacLeod is separated from the Indian
Recent calcareous stromatolites from Laguna Mormona (Baja California), Mexico
ABSTRACT Recent stromatolites produced by in situ aragonite precipitation occur in a hypersaline coastal pond on the west coast of Baja California, Mexico. These structures range up to 15 cm in
