Microbial diversity on a marble monument: a case study
(Environmental Earth Sciences, 2010)In the presented case study, ascomycete fungi and green algae on a marble monument were identified by comparisons of the 18S rRNA gene sequences, which were obtained from DNA either from environmental samples or from ... -
Physical weathering of building stones induced by freeze–thaw action: a laboratory long-term study
(Environmental Earth Sciences, 2010)Damages to natural building stones induced by the action of frost are considered to be of great importance. Commonly, the frost resistance of building stones is checked by standardised freeze–thaw tests before using. ... -
Optimized extraction of dimension stone blocks
(Environmental Earth Sciences, 2010)The profitable production of dimension stone mainly depends on the extractable block size. The regularity and volume of the blocks are of critical importance, and are controlled by the three-dimensional pattern of the ... -

Microbial and Chemical Characterization of Underwater Fresh Water Springs in the Dead Sea
(PLoS ONE, 2012-06-05)Due to its extreme salinity and high Mg concentration the Dead Sea is characterized by a very low density of cells most of which are Archaea. We discovered several underwater fresh to brackish water springs in the Dead ... -
Effects of Insect Mass Outbreaks on Throughfall Composition in Even Aged European Pine Stands - Implications for the C and N Cycling
(Journal of Earth Science & Climatic Change, 2011)In this paper we report on the herbivore-affected C and N concentrations in the throughfall and altered canopy to soil transfer during a Pine Lappet (Dendrolimus pini L) mass infestation in 60-year-old Scots Pine (Pinus ... -
Moisture expansion as a deterioration factor for sandstone used in buildings
(Environmental Earth Sciences, 2010)The expansion processes that develop in building stones upon changes of moisture content may be an important contributing factor for their deteriorations. Until recently, few data could be found in the literature concerning ... -
The Neoproterozoic-early Paleozoic metamorphic and magmatic evolution of the Eastern Sierras Pampeanas: an overview
(International Journal of Earth Sciences, 2010)The Eastern Sierras Pampeanas were structured by three main events: the Ediacaran to early Cambrian (580–510 Ma) Pampean, the late Cambrian–Ordovician (500–440 Ma) Famatinian and the Devonian-Carboniferous (400–350 Ma) ... -
Spatial analysis of loess and loess-like sediments in the Weser- Aller catchment (Lower Saxony and Northern Hesse, NW Germany)

The Itajaí foreland basin: a tectono-sedimentary record of the Ediacaran period, Southern Brazil
(International Journal of Earth Sciences, 2010)The Itajaí Basin located in the southern border of the Luís Alves Microplate is considered as a peripheral foreland basin related to the Dom Feliciano Belt. It presents an excellent record of the Ediacaran period, and its ... -
Short-term fluctuations in vegetation and phytoplankton during the Middle Eocene greenhouse climate: a 640-kyr record from the Messel oil shale (Germany)
(International Journal of Earth Sciences, 2010)The Palaeogene was the most recent greenhouse period on Earth. Especially for the Late Palaeocene and Early Eocene, several superimposed short-term hyperthermal events have been described, including extremes such as the ... -
Lattice-preferred orientations of late-Variscan granitoids derived from neutron diffraction data: implications for magma emplacement mechanisms
(International Journal of Earth Sciences, 2010)The lattice-preferred orientation (LPOs) of two late-Variscan granitoids, the Meissen monzonite and the Podlesí dyke granite, were determined from high-resolution time-of-flight neutron diffraction patterns gained at the ... -
Fluid/rock interaction and mass transfer in continental subduction zones: constraints from trace elements and isotopes (Li, B, O, Sr, Nd, Pb) in UHP rocks from the Chinese Continental Scientific Drilling Program, Sulu, East China
(Contributions to Mineralogy and Petrology, 2011)In order to better understand the role of fluids during subduction and subsequent exhumation, we have investigated whole-rock and mineral chemistry (major and trace elements) and Li, B as well as O, Sr, Nd, Pb isotopes on ... -
