(2016) present various methods to estimate parameters that are relevant for probabilistic seismic-hazard assessment. One of these parameters, although not the most influential, is the maximum possible earthquake magnitude m(max). I show that the proposed estimation of m(max) is based on an erroneous equation related to a misuse of the estimator in Cooke (1979) and leads to unstable results. So far, reported finite estimations of m(max) arise from data selection, because the estimator in Kijko et al. (2016) diverges with finite probability. This finding is independent of the assumed distribution of earthquake magnitudes. For the specific choice of the doubly truncated Gutenberg-Richter distribution, I illustrate the problems by deriving explicit equations. Finally, I conclude that point estimators are generally not a suitable approach to constrain m(max).}, language = {en} } @misc{WetzelKempkaKuehn2017, author = {Wetzel, Maria and Kempka, Thomas and K{\"u}hn, Michael}, title = {Predicting macroscopic elastic rock properties requires detailed information on microstructure}, series = {Energy procedia}, volume = {125}, journal = {Energy procedia}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1876-6102}, doi = {10.1016/j.egypro.2017.08.195}, pages = {561 -- 570}, year = {2017}, abstract = {Predicting variations in macroscopic mechanical rock behaviour due to microstructural changes, driven by mineral precipitation and dissolution is necessary to couple chemo-mechanical processes in geological subsurface simulations. We apply 3D numerical homogenization models to estimate Young's moduli for five synthetic microstructures, and successfully validate our results for comparable geometries with the analytical Mori-Tanaka approach. Further, we demonstrate that considering specific rock microstructures is of paramount importance, since calculated elastic properties may deviate by up to 230 \% for the same mineral composition. Moreover, agreement between simulated and experimentally determined Young's moduli is significantly improved, when detailed spatial information are employed.}, language = {en} } @misc{WawrzenitzKrohe2016, author = {Wawrzenitz, Nicole and Krohe, Alexander}, title = {Deformed monazite yields high-temperature tectonic ages}, series = {Geology}, volume = {44}, journal = {Geology}, publisher = {American Institute of Physics}, address = {Boulder}, issn = {0091-7613}, doi = {10.1130/G37394C.1}, pages = {E377 -- E377}, year = {2016}, language = {en} } @misc{WangHerzschuhLiuetal.2017, author = {Wang, Yongbo and Herzschuh, Ulrike and Liu, Xingqi and Korup, Oliver and Diekmann, Bernhard}, title = {Reply to Chong Xu's comment on: Wang, Yongbo; Herzschuh, Ulrike; Liu, Xingqi; Korup, Oliver; Diekmann, Bernhard: A high-resolution sedimentary archive from landslide-dammed Lake Mengda, north-eastern Tibetan Plateau. - Journal of Paleolimnology. - 51 (2014), S. 303 - 312}, series = {Journal of paleolimnolog}, volume = {57}, journal = {Journal of paleolimnolog}, publisher = {Springer}, address = {Dordrecht}, issn = {0921-2728}, doi = {10.1007/s10933-016-9937-8}, pages = {163 -- 164}, year = {2017}, language = {en} } @misc{WangOswaldGraeffetal.2020, author = {Wang, Wei-shi and Oswald, Sascha and Gr{\"a}ff, Thomas and Lensing, Hermann-Josef and Liu, Tie and Strasser, Daniel and Munz, Matthias}, title = {Correction: Impact of river reconstruction on groundwater flow during bank filtration assessed by transient three-dimensional modelling of flow and heat transport. - Hydrogeology Journal. - Berlin: Springer. - 28 (2020) , S. 723. - https://doi.org/10.1007/s10040-019-02063-3}, series = {Hydrogeology journal : official journal of the International Association of Hydrogeologists}, volume = {28}, journal = {Hydrogeology journal : official journal of the International Association of Hydrogeologists}, number = {7}, publisher = {Springer}, address = {Berlin ; Heidelberg ; New York, NY}, issn = {1431-2174}, doi = {10.1007/s10040-020-02221-y}, pages = {2633 -- 2634}, year = {2020}, language = {en} } @misc{WalzGretRegameyLavorel2016, author = {Walz, Ariane and Gret-Regamey, Adrienne and Lavorel, Sandra}, title = {Social valuation of ecosystem services in mountain regions}, series = {Regional environmental change}, volume = {16}, journal = {Regional environmental change}, publisher = {Springer}, address = {Heidelberg}, issn = {1436-3798}, doi = {10.1007/s10113-016-1028-x}, pages = {1985 -- 1987}, year = {2016}, language = {en} } @misc{WagnerOswaldFrick2018, author = {Wagner, Kathrin and Oswald, Sascha and Frick, Annett}, title = {Multitemporal soil moisture monitoring by use of optical remote sensing data in a dike relocation area}, series = {Remote Sensing for Agriculture, Ecosystems, and Hydrology XX}, volume = {10783}, journal = {Remote Sensing for Agriculture, Ecosystems, and Hydrology XX}, publisher = {SPIE-INT Soc Optical Engineering}, address = {Bellingham}, isbn = {978-1-5106-2150-3}, issn = {0277-786X}, doi = {10.1117/12.2325319}, pages = {5}, year = {2018}, abstract = {The nature restoration project 'Lenzener Elbtalaue', realised from 2002 to 2011 at the river Elbe, included the first large scale dike relocation in Germany (420 ha). Its aim was to initiate the development of endangered natural wetland habitats and processes, accompanied by greater biodiversity in the former grassland dominated area. The monitoring of spatial and temporal variations of soil moisture in this dike relocation area is therefore particularly important for estimating the restoration success. The topsoil moisture monitoring from 1990 to 2017 is based on the Soil Moisture Index (SMI)1 derived with the triangle method2 by use of optical remotely sensed data: land surface temperature and Normalized Differnce Vegetation Index are calculated from Landsat 4/5/7/8 data and atmospheric corrected by use of MODIS data. Spatial and temporal soil moisture variations in the restored area of the dike relocation are compared to the agricultural and pasture area behind the new dike. Ground truth data in the dike relocation area was obtained from field measurements in October 2017 with a FDR device. Additionally, data from a TERENO soil moisture sensor network (SoilNet) and mobile cosmic ray neutron sensing (CRNS) rover measurements are compared to the results of the triangle method for a region in the Harz Mountains (Germany). The SMI time series illustrates, that the dike relocation area has become significantly wetter between 1990 and 2017, due to restructuring measurements. Whereas the SMI of the dike hinterland reflects constant and drier conditions. An influence of climate is unlikely. However, validation of the dimensionless index with ground truth measurements is very difficult, mostly due to large differences in scale.}, language = {en} } @misc{VoropaevKorochantsevPetukhovetal.2016, author = {Voropaev, S. and Korochantsev, A. and Petukhov, D. and Kocherov, A. and Kaeter, David and Ziemann, Martin Andreas and Boettger, Ute}, title = {Ordinary chondrites of Chelyabinsk meteorite and comparison with asteroid 25143 (Itokawa)}, series = {PLoS one}, volume = {51}, journal = {PLoS one}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {1086-9379}, pages = {A644 -- A644}, year = {2016}, language = {en} } @misc{ThiedeEhlers2013, author = {Thiede, Rasmus Christoph and Ehlers, Todd}, title = {Large spatial and temporal variations in Himalayan denudation (vol 371, pg 278, 2013)}, series = {Earth \& planetary science letters}, volume = {374}, journal = {Earth \& planetary science letters}, number = {13}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0012-821X}, doi = {10.1016/j.epsl.2013.07.004}, pages = {256 -- 257}, year = {2013}, language = {en} } @misc{StoltnowSeifertJeskeetal.2019, author = {Stoltnow, Malte and Seifert, Thomas and Jeske, Tilman J. and Gilbricht, Sabine and Krause, Joachim}, title = {Contributions to the mineralogical and geochemical characterization of Fe-Sn-Zn-Cu-In skarn-type mineralization in the Schwarzenberg mining district, Germany}, series = {Life with Ore Deposits on Earth - 15th SGA Biennial Meeting 2019}, journal = {Life with Ore Deposits on Earth - 15th SGA Biennial Meeting 2019}, publisher = {SGA Soc Geology Applied mineral depositis}, address = {Geneva}, pages = {1089 -- 1092}, year = {2019}, abstract = {The Schwarzenberg mining district in the western Erzgebirge hosts numerous skarn-hosted tin-polymetallic deposits, such as Breitenbrunn. The St. Christoph mine is located in the Breitenbrunn deposit and is the locus typicus of christophite, an iron-rich sphalerite variety, which can be associated with indium enrichment. This study presents a revision of the paragenetic scheme, a contribution to the indium behavior and potential, and discussion on the origin of the sulfur. This was achieved through reflected light microscopy, SEM-based MLA, EPMA, and bulk mineral sulfur isotope analysis on 37 sulfide-rich skarn samples from a mineral collection. The paragenetic scheme includes: a pre-mineralization stage of anhydrous calc-silicates and hydrous minerals; an oxide stage, dominated by magnetite; a sulfide stage of predominantly sphalerite, minor pyrite, chalcopyrite, arsenopyrite, and galena. Some sphalerite samples present elevated indium contents of up to 0.44 wt\%. Elevated iron contents (4-10 wt\%) in sphalerite can be tentatively linked to increased indium incorporation, but further analyses are required. Analyzed sulfides exhibit homogeneous delta S-34 values (-1 to +2 parts per thousand VCDT), assumed to be post-magmatic. They correlate with other Fe-Sn-Zn-Cu-In skarn deposits in the western Erzgebirge, and Permian vein-hosted associations throughout the Erzgebirge region.}, language = {en} }
