Correlation between volumetric strain and porosity in saturated limestones

Almeida, André | Costa e Silva, Matilde

2018

Porosity and permeability are two of the most important parameters regarding the knowledge about how rock masses are affected in terms of their geology and physical and mechanical behavior, whether in Mining or Petroleum Engineer. This matter is quite debated in both theoretical and practical...

Contribution of acoustic emissions for the study of fracture in rocks

Neves, João | Costa e Silva, Matilde | Falcão Neves, Paula | Paneiro, Gustavo

2016

Acoustic emissions (AE) are a tool commonly used in a wide variety of building materials for the quantification of structural damage. Given the potential of the application of acoustic emission techniques, a case study of limestones is presented in order to study the location of acoustic...

Criteria for Geotechnical Characterization of Rock Masses for Underground Works

Costa e Silva, Matilde | Falcão Neves, Paula | Caranhola Pereira, Hugo | Reis e Sousa, Manuel

2001

This work points out the main criteria for geotechnical characterization in rock masses, is described the steps of each fases of characterization and is enfasized the importance of choosing the correct group of parameters to established a suitable geotechnical classification system and help...

Spreading angle of gas and particle jets from shock-tube experiments

Cigala, Valeria | Kueppers, Ulrich | Dingwell, Donald

2021

Shock-tube experiments can be used to investigate the relationship between ejection dynamics and shallow plumbing system characteristics in volcanic scenario. Gas and-particle jets were generated using shock-tube rapid decompression experiments and their gas and particle spreading angles have...

Weight, size, porosity characterization of pumices from Minoan Eruption in Santorini (Greece)

Pisello, Alessandro | Kueppers, Ulrich

2021

The dataset shows the characterization of a set of clasts from Santorini Island: pumices collected from two deposits: Minoan A and Minoan B (Druitt et al. 1999), two levels of the product emplaced by Minoan eruption of Santorini caldera, ca. 1650 B.C. Pumices were weighted, and then...

Dataset of experimental fragmentation results and petrophysical properties for pyroclasts from Mt. Pelée, Martinique

Huebsch, Mila | Kueppers, Ulrich | Carazzo, Guillaume | Cimarelli, Corrado | Hess, Kai-Uwe | Hornby, Adrian | Lejeune, Anne-Marie | Michaud-Dubuy, Audrey | Perugini, Diego | Weller, Daniel | Heap, Michael J. | Dingwell, Donald B.

2023

Mt. Pelée is a stratovolcano in Martinique, which produces eruptions drastically varying in style from lava dome formation and collapse to long-lasting violent explosivity. This dataset provides results from petrophysical analysis and fragmentation experiments of pyroclastic samples from Mt....

Drained ring-shear test data of wet silica powder-glass beads-PVC powder mixture “CM2” used for analogue modelling in the laboratory for experimental tectonics (LET) at RomaTre University, Rome, Italy

Reitano, Riccardo | Rosenau, Matthias | Conrad, Ethan M. | Faccenna, Claudio | Funiciello, Francesca

2023

This dataset provides friction data from drained ring-shear tests on a wet (water saturated) silica powder-glass beads-PVC powder mixture (40:40:20 wt.%) “CM2”, used in analogue modelling of tectonic and erosion processes as a rock analogue for the earth’s upper crust (e.g. Conrad et al., 2023,...

Simulating the in situ physical properties of the upper Muschelkalk aquifer

Shih, Pei-Ju Rita | Almqvist, Bjarne | Zappone, Alba

2018

The Swiss Molasse Basin (SMB) and the adjacent Folded Jura contain the most suitable deep aquifers for storage in Switzerland (Chevalier et al., 2010). Due to the unsuccessful petroleum exploration in the SMB and Jura, the basin has not been industrially developed and knowledge of the...

A database of analogue models documenting fault reactivation during multiphase extension.

Wang, Liang | Maestrelli, Daniele | Corti, Giacomo | Zou, Yaoyao | Shen, Chuanbo

2024

In this dataset we provide top-view photos and perspective photos (to create topographic data, i.e. Digital Elevation Models, DEMs) documenting analogue model deformation. For more details on modelling setup, experimental series Wang et al. (2021), to which this dataset is supplementary...

Database of in situ Raman spectra from Ca- and Mg-ATP solutions at 80 °C, 100 °C and 120 °C for determination of the rate constant of the ATP hydrolysis

Moeller, Christoph | Testemale, Denis | Schmidt, Christian | Kokh, Maria A. | Guyot, François | Wilke , Max

2025

In biochemical systems, enzymes facilitate the endergonic reaction of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) via pathways such as oxidative phosphorylation by mem-brane-bound ATP synthase or substrate-level phosphorylation. The energy stored in ATP is re-leased through...
