Microbial fabric formation in spring mounds ("microbialites") of alkaline salt lakes in the Badain Jaran Sand Sea, PR China
; Hofmann, Jürgen; (Palaios, 1998)
The large sandy desert of Badnin Jaran Shamo, Inner Mongolia, has several salt lakes located among megadunes with crests as high as 400 m. Most of the lakes are hypo- to hypersaline and alkaline, with pH values between ... -
Microbial iron reduction does not release microplastics from organo‐metallic aggregates
; (Limnology and Oceanography Letters, 2022-03-23)
Iron flocculants play a major role in the remediation of water bodies, removing particulate pollutants such as microplastics through floc formation. Such flocs are prone to microbial iron reduction while lying on top of ... -
Microbial-, fusulinid limestones with large gastropods and calcareous algae: an unusual facies from the Early Permian Khao Khad Formation of Central Thailand
; ; ; (Facies, 2020-07-14)
The Early Permian (Kungurian) Khao Khad Formation of Central Thailand consists mostly of carbonates deposited on the western margin of the Indochina Terrane. This formation has yielded unusual microbial-fusulinid limestones ... -
Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia
; Reimer, Andreas; (Journal of sedimentary research, 2003)
The crater lake of the small volcanic island Satonda, Indonesia, is unique for its red-algal microbial reefs thriving in marinederived water of increased alkalinity. The lake is a potential analogue for ancient oceans ... -

Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia - Reply
; Reimer, Andreas; (Journal of sedimentary research, 2004)
Our paper (Arp et al. 2003) revises previous studies of Kaz´mierczak and Kempe (1990, 1992), Kempe and Kaz´mierczak (1990a, 1990b, 1993), and Kempe et al. (1996, 1997) on Lake Satonda reefs with regard to biofilm calcification ... -

Microbialites and hydrochemistry of the crater lake of Satonda
Kempe, Stephan; Kazmierczak, Józef; Reimer, Andreas; Landmann, Guenter; (Globale und regionale Steuerungsfaktoren biogener Sedimentation, 1996)
The Satonda crater lake is up to now the only known "marine" lake with an increased alkalinity compared to seawater. Therefore, the lake contains a decreased amount of Ca2 +. Its pH values about 8.5-8.6. The lake was ... -
Microbially promoted calcite precipitation in the pelagic redoxcline: Elucidating the formation of the turbid layer
; ; ; ; ; ; ; ; ; ; (Geobiology, 2022-05-05)
Large bell‐shaped calcite formations called “Hells Bells” were discovered underwater in the stratified cenote El Zapote on the Yucatán Peninsula, Mexico. Together with these extraordinary speleothems, divers found a white, ... -
Microcracking in calcite and dolomite marble: microstructural influences and effects on properties
(Environmental Earth Sciences, 2012)Microstructure‐based finite-element analysis with a microcracking algorithm was used to simulate an actual degradation phenomenon of marble structures, i.e., microcracking. Both microcrack initiation and crack propagation ... -
Microfabrics and deformation processes in magmatic veins of the Thuringian Forest, Germany
Neubert, Jana; Klauw, Sebastiaan van der; (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
The research area is located in the Ruhla-Brotterode crystalline complex in the western part of the Thuringian Forest (Germany), about 20km southsouthwest of Eisenach. The investigated outcrops occur at the eastern and ... -
