Microbial fabric formation in spring mounds ("microbialites") of alkaline salt lakes in the Badain Jaran Sand Sea, PR China
(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 ... -
Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia
(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
(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
(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 ... -
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 ... -
Microseismicity and Lava Flows Hint at Magmato‐Tectonic Processes Near the Southern Tip of the Fonualei Rift and Spreading Center in the Lau Basin
(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 ... -
Microstructural criteria for synseismic loading and postseismic creep in the uppermost plastosphere - an example from the Sesia Zone, Western Alps
(Univ. Bochum, 2002)Anhand des Modellfalls der Sesia Zone in den West-Alpen werden mikrostrukturelle Kriterien für syn- und postseismische Deformation in der oberen Plastosphäre in Folge eines großen Erdbebens in der überlagernden Schizosphäre ... -
Middle and Late Devonian paleogeography of the eastern Anti-Atlas (Morocco)
(International Journal of Earth Sciences, 2021-04-17)The eastern Anti-Atlas of Morocco represents one of the most completely exposed and perfectly documented biostratigraphic records of the entire Devonian worldwide. Paleogeographically it is clearly differentiated into ... -
Mineralogical and geochemical characterization of high-medieval lead–silver smelting slags from Wiesloch near Heidelberg (Germany)—an approach to process reconstruction
(Archaeological and Anthropological Sciences, 2010)Here, we present detailed electron microprobe analyses and age data of high-medieval lead–silver smelting slags. The mineral composition data provide a database of all silicate and oxide phases in the slag. Bulk chemistry ... -
Miniaturized biosignature analysis reveals implications for the formation of cold seep carbonates at Hydrate Ridge (off Oregon, USA)
(Biogeosciences, 2008)Methane-related carbonates from Hydrate Ridge typically show several macroscopically distinguishable mineral phases, namely whitish aragonite, lucent aragonite, and gray micrite. The relationship of these phases to ... -
Mitigating Uranium in Ground Water: Prospects and Limitations
(Environmental Science & Technology, 2003)Removal of uranium(VI) by zero-valent iron (ZVI) has been suggested as a feasible pathway to control uranium contaminations in seepage waters. Available information in literature however presents discrepant evidence on ... -
MODELING AND SIMULATION OF IRON/SAND FILTERS
(Revue des sciences de l'eau, 2012)This article develops a mathematical model of Iron (Fe0) /sand filter taking into account the loss of porosity during the filtration process. The mass transport advection-dispersion equation is derived to predict, through ... -
Modeling Lithospheric Thickness Along the Conjugate South Atlantic Passive Margins Implies Asymmetric Rift Initiation
(Tectonics, 2022-09-20)The lithospheric architecture of passive margins is crucial for understanding the tectonic processes that caused the breakup of Gondwana. We highlight the evolution of the South Atlantic passive margins by a simple thermal ... -
Modeling Net Ecosystem Exchange for Grassland in Central Kazakhstan by Combining Remote Sensing and Field Data
(Remote Sensing, 2009)Carbon sequestration was estimated in a semi-arid grassland region in Central Kazakhstan using an approach that integrates remote sensing, field measurements and meteorological data. Carbon fluxes for each pixel of 1 × ... -
