A Volcanic Ash Layer in the Nördlinger Ries Impact Structure (Miocene, Germany): Indication of Crater Fill Geometry and Origins of Long‐Term Crater Floor Sagging
Arp, Gernot; Dunkl, István; Jung, Dietmar; Karius, Volker; Lukács, Réka; Zeng, Lingqi; Reimer, Andreas; Head, James W. (Journal of Geophysical Research: Planets, 2021-04-09)Since its recognition as an impact structure 60 years ago, no volcanics were anticipated in the circular depression of the 14.8 Ma old Nördlinger Ries. Here, we describe for the first time a volcanic ash‐derived ... -
Assessing the utility of trace and rare earth elements as biosignatures in microbial iron oxyhydroxides
Heim, Christine; Simon, Klaus; Ionescu, Danny; Reimer, Andreas; De Beer, Dirk; Quéric, Nadia-Valérie; Reitner, Joachim; Thiel, Volker (Frontiers in Earth Science, 2015)Microbial iron oxyhydroxides are common deposits in natural waters, recent sediments, and mine drainage systems. Along with these minerals, trace and rare earth elements (TREE) are being accumulated within the mineralizing ... -
Lake Van, Eastern Anatolia, Hydrochemistry and History
Reimer, Andreas; Landmann, Guenter; Kempe, Stephan (Aquatic GeochemistryAquatic Geochemistry, 2008)Saline, 450-m-deep Lake Van (Eastern Anatolia, Turkey) is, with 576 km3, the third largest closed lake on Earth and its largest soda lake. In 1989 and 1990, we investigated the hydrochemistry of the lake’s water column and ... -
Microbialite formation in seawater of increased alkalinity, Satonda Crater Lake, Indonesia
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
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; Reitner, Joachim (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 ...
