Structural geology of the Fuegian Andes and Magallanes fold-and-thrust belt - Tierra del Fuego Island

Geologica Acta, 2008
A synthesis of the structural geology of the Tierra del Fuego Island, which integrates a new data set derived from field surveys and literature data of the last few years, is presented here. The main geological features of the region developed during the

Exploring Lime Mortar Microstructure: Investigating the Impact of Mixed-in Additives and their Role in Salt Efflorescence Inhibition [PDF]

MATEC Web of Conferences
This study presents the analysis of the crystallization impact in four lime-based mortar mixtures in order to determine the extent of decay during salt crystallization, affected by the use of additives and change in microstructure.

Identification of Natural and Forcing Frequencies through Noisy Measurements Acquired in Operational Conditions on a Hospital Building

Advances in Civil Engineering
Operational modal analysis is a robust and practical approach to structural health monitoring which assumes white noise as input. Therefore, the accuracy of this method can be compromised when dealing with colored unknown excitations, in which, for ...

Thick-Skinned and Thin-Skinned Tectonics: A Global Perspective

Geosciences, 2017
This paper gives an overview of the large-scale tectonic styles encountered in orogens worldwide. Thin-skinned and thick-skinned tectonics represent two end member styles recognized in mountain ranges.

Effects of mechanical properties of the underburden on induced seismicity along a basement fault during hydrogen storage in a depleted reservoir

iScience
Summary: This study models the geomechanical deformation of a depleted gas field, wherein gaseous hydrogen is stored in a North Sea reservoir, and is cyclically injected and withdrawn.

Straight impact crater rim segments on Mercury

Journal of Maps
The formation of straight impact crater rims is widely accepted to be influenced by preexisting lithospheric structure. We investigate the distribution and orientations of straight crater rim segments across Mercury. We devise a mapping workflow aimed at

Experiencing Structural Geology

Journal of Geological Education, 1978
Undergraduate students at the University of Arizona learn principles of structural geology while unraveling the complexities of well exposed, deformed rocks close to campus. Students spend all of their “lab” time in the field engaged in structural mapping and analysis.
