Natural building stones of Mexico–Tenochtitlán: their use, weathering and rock properties at the Templo Mayor, Palace Heras Soto and the Metropolitan Cathedral
Wedekind, Wanja; Ruedrich, Joerg; Siegesmund, Siegfried (Environmental Earth Sciences, 2011)In the Aztec period and in colonial times different natural stones originating in the Valley of Mexico were used for building construction. Stone weathering was investigated onsite at various historical buildings within ... -
Rettung für das Markttor von Milet: Schadensanalysen an Marmor, Mörtel und Stahl
Siegesmund, Siegfried; Ruedrich, Joerg (Georgia Augusta, 2005) -
Syn-kinematic magma ascent and batholith inflation (Sierra de San Luis/Argentina)
Steenken, André; Siegesmund, Siegfried; Luchi, Mónica G. López de; Rapalini, Augusto; Wemmer, Klaus (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The measurement of the anisotropy of the magnetic susceptibility (AMS) is now routinely used since more than four decades in the analyses of rock fabrics in granitic rocks (e.g. Stacy 1960, Henry 1975, Gleizes et al. 1993). ... -
The Neoproterozoic-early Paleozoic metamorphic and magmatic evolution of the Eastern Sierras Pampeanas: an overview
Steenken, André; López de Luchi, Mónica; Martínez Dopico, Carmen; Drobe, Malte; Wemmer, Klaus; Siegesmund, Siegfried (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) ... -
The Río de la Plata Craton: a review of units, boundaries, ages and isotopic signature
Oyhantçabal, Pedro; Siegesmund, Siegfried; Wemmer, Klaus (International Journal of Earth Sciences, 2010)A review of the lithostratigraphic units in the Río de la Plata Craton and of new and previously published geochronological, isotopic and geophysical data is presented. Sm–Nd TDM model ages between 2.6 and 2.2 Ga characterize ... -
The Sierra Ballena Shear Zone in the southernmost Dom Feliciano Belt (Uruguay): evolution, kinematics, and deformation conditions
Oyhantçabal, Pedro; Siegesmund, Siegfried; Wemmer, Klaus; Layer, Paul (International Journal of Earth Sciences, 2009)The Sierra Ballena Shear Zone (SBSZ) is part of a high-strain transcurrent system that divides the Neoproterozoic Dom Feliciano Belt of South America into two different domains. The basement on both sides of the SBSZ shows ... -
The tectonic significance of K/Ar illite fine-fraction ages from the San Luis Formation (Eastern Sierras Pampeanas, Argentina)
Wemmer, Klaus; Steenken, André; Müller, Stefan; Luchi, Mónica; Siegesmund, Siegfried (International Journal of Earth Sciences, 2011)The Sierra de San Luis forms the southern tip of the Eastern Sierras Pampeanas in central Argentina. Two narrow belts of low-grade phyllites and quartz arenites, i.e. the San Luis Formation, have accommodated part of the ... -
The transpressional connection between Dom Feliciano and Kaoko Belts at 580–550 Ma
Oyhantçabal, Pedro; Siegesmund, Siegfried; Wemmer, Klaus; Passchier, Cees (International Journal of Earth Sciences, 2010)A new U–Pb SHRIMP age of 551 ± 4 Ma on a mylonitic porphyry that intruded into the Sierra Ballena Shear Zone (Southernmost Dom Feliciano Belt, Uruguay) and a review of relevant published data make possible a more refined ... -
Time constraints on the tectonic evolution of the Eastern Sierras Pampeanas (Central Argentina)
Siegesmund, Siegfried; Steenken, André; Martino, Roberto; Wemmer, Klaus; López de Luchi, Mónica; Frei, Robert; Presnyakov, Sergej; Guereschi, Alina (International Journal of Earth Sciences, 2009)The application of the SHRIMP U/Pb dating technique to zircon and monazite of different rock types of the Sierras de Córdoba provides an important insight into the metamorphic history of the basement domains. Additional ... -
Trachyte weathering in the urban built environment related to air quality
Germinario, Luigi; Siegesmund, Siegfried; Maritan, Lara; Simon, Klaus; Mazzoli, Claudio (Heritage Science, 2017)Decay of trachyte used as building stone in urban environment was investigated through the analysis of crusts and patinas found on trachyte of the Euganean Hills in the Renaissance city walls of Padua, northeastern Italy. ... -
Weathering behaviour and construction suitability of dimension stones from the Drei Gleichen area (Thuringia, Germany)
Stück, Heidrun; Siegesmund, Siegfried; Rüdrich, Jörg (Environmental Earth Sciences, 2011)The construction suitability of a dimension stone depends on its weathering properties along with the petrology and the petrophysical properties. The aim of this study was to evaluate the suitability of the dimension stones ... -
Weathering of volcanic tuff rocks caused by moisture expansion
Wedekind, Wanja; López-Doncel, Rubén; Dohrmann, Reiner; Kocher, Mathias; Siegesmund, Siegfried (Environmental Earth Sciences, 2012)Moisture expansion in natural building stones is considered one of the most important factors affecting their weathering and deterioration. The processes that may be responsible for the expansion under determinate relative ...
