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 ... -

Microfacies, sedimentation and some aspects of diagenesis of Upper Jurassic sediments from the elevated part of the Northern peri-Tethyan Shelf - a comparative study on the Lochen area (Schwäbische Alb) and the Cracow area (Cracow-Wielun Upland, Poland)
(Selbstverlag Fachbereich Geowissenschaften, FU Berlin, 1997)
At the beginning of Late Jurassic both the Lochen (LA) and the Cracow areas (CA) were palaeotopographic highs in an epicontinental basin located at the stable northern margin of the Tethyan Ocean. The topographically high ... -
Micromorphology and Site Formation at Hohle Fels Cave, Schwabian Jura, Germany
(E&G – Quaternary Science Journal; Vol.53, No. 1)Die Höhle Hohle Fels liegt auf der Schwäbischen Alb bei Schelklingen und beinhaltet eine stratigraphische Folge, die mindestens 36.000 Jahre zurück geht und Aurignacien-, Gravettien- und Magdalénien-Fundschichten beinhaltet. ... -
Microphysical Pathways Active Within Thunderstorms and Their Sensitivity to CCN Concentration and Wind Shear
; (Journal of Geophysical Research: Atmospheres, 2023-03-01)
The impact of cloud condensation nuclei (CCN) concentration on microphysical processes within thunderstorms and the resulting surface precipitation is not fully understood yet. In this work, an analysis of the microphysical ... -
Microplastics as a sedimentary component in reef systems: A case study from the Java Sea
; ; ; (Sedimentology, 2021-06-12)
Microplastic pollution has been reported from coral reef systems all over the tropics. Exposure to microplastics has several negative impacts on coral health, such as bleaching, tissue necrosis, or an impairment of the ... -
Microseismicity and Lava Flows Hint at Magmato‐Tectonic Processes Near the Southern Tip of the Fonualei Rift and Spreading Center in the Lau Basin
; Cremanns, M.; ; ; ; (Journal of Geophysical Research: Solid Earth, 2021-04-27)
Spreading centers in the proximity of back‐rolling subduction zones constitute an ideal natural laboratory to investigate the interaction of magmatism and tectonism during the early evolution of back‐arc basins. Using ... -
Microsites and early litter decomposition patterns in the soil and forest canopy at regional scale
; ; (Biogeochemistry, 2020-10-13)
Plant litter decomposition is a key ecological process that is mostly studied at the forest floor. However, decomposition generally starts in the canopy. In this study, we evaluated the effect of litter composition and ... -

Microstructural evidence of impact-induced crystalplastic deformation and postshock annealing of quartz
; Spray, John G. (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
During impact, rocks at the surface and accessible depths encounter extreme conditions. The hydrostatic component of the shock wave-associatedstress, the so-called shock pressure, canreach several tens of GPa in the central ... -
Microstructures of fibrous halite veins
; Pennock, Gill; Schléder, Zsolt; Burliga, Stansilaw; (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Halite veins hosted in clastic sedimentary rocks are frequently observed next to evaporite layers. Their microstructure can be enhanced by gamma irradiation and etching, which can be used to infer the deformation mechanism of ... -
