Comparative Evaluation of Statistical and Fractal Approaches for JRC Calculation Based on a Large Dataset of Natural Rock Traces
(
- Rock Mechanics and Rock Engineering
, 2021-02-03)
After the publication of the type-profiles for the estimation of the joint roughness coefficient (JRC) a discussion evolved about how to adequately use these traces. Based on the chart numerous researchers assembled ...
In Situ Stress State of the Ruhr Region (Germany) and Its Implications for Permeability Anisotropy
(
- Rock Mechanics and Rock Engineering
, 2021-09-28)
In this study, we carried out reactivation potential analysis of discontinuities revealed from four exploration boreholes penetrating heavily faulted and folded Upper Carboniferous rock strata of the Ruhr region. We performed ...
Determination of Fracture Toughness of Mode I Fractures from Three-Point Bending Tests at Elevated Confining Pressures
(
- Rock Mechanics and Rock Engineering
, 2021-03-23)
Fracture toughness is one of the key parameters for the characterization of brittle rock fracturing. Yet, constraints on it mainly rest on measurements performed at ambient pressure, although rock fracturing frequently ...
Sedimentology of a coastal shelf sector characterised by multiple bedload boundaries: Plettenberg Bay, inner Agulhas Bank, South Africa
(
- Geo-Marine Letters
, 2021-07-06)
The study deals with a large sand body (spit-bar) attached to the eastern tip of the Robberg Peninsula, Plettenberg Bay, South Africa. To date, the bar has prograded about 8 km beyond the tip of the peninsula. The bar top ...
Damage Evolution of Coal with Inclusions Under Triaxial Compression
(
- Rock Mechanics and Rock Engineering
, 2021-03-23)
Along with the advance of the working face, coal experiences different loading stages. Laboratory tests and numerical simulations of fracture and damage evolution aim to better understand the structural stability of coal ...
Eduard Suess: the first honorary president of the Geologische Vereinigung, is 190 years old
(
- International Journal of Earth Sciences
, 2021-09-27)
This paper is a remembering the first honorary president of the Geologische Vereinigung on his 190th Anniversary. He still illuminates our path in our endeavours to understand not only our planet, but also others in our ...
Special Issue on Rock Fracturing and Fault Activation: Experiments and Models
(
- Rock Mechanics and Rock Engineering
, 2021-09-27)
This paper is the editoral of a special issue, that intends to summarize the highlights of the conference programme consisting of 8 keynote lectures, 47 oral presentations and 26 poster presentations given by rock mechanics ...
New constraints on the exhumation history of the western Tauern Window (European Alps) from thermochronology, thermokinematic modeling, and topographic analysis
(
- International Journal of Earth Sciences
, 2021-08-07)
The Brenner normal fault bounds the Tauern Window to the west and accommodated a significant portion of the orogen-parallel extension in the Eastern Alps. Here, we use zircon (U–Th)/He, apatite fission track, and apatite ...
Provenance of lower Palaeozoic metasediments of the East Odenwald (Mid-German-Crystalline Zone, Variscides)—a correlation with the East European Platform (Poland)
(
- International Journal of Earth Sciences
, 2021-09-21)
U–Pb age spectra of detrital zircons related to the East European Platform could be traced in paragneiss through the whole Mid-German-Crystalline Zone (Variscides, Central Europe) from the Odenwald via the Spessart to the ...
The Di models method: geological 3-D modeling of detrital systems consisting of varying grain fractions to predict the relative lithological variability for a multipurpose usability
(
- Bulletin of Engineering Geology and the Environment
, 2021-12-21)
The coexistence of a wide variety of subsurface uses in urban areas requires increasingly demanding geological prediction capacities for characterizing the geological heterogeneities at a small-scale. In particular, detrital ...
