Predictability of properties of a fractured geothermal reservoir: the opportunities and limitations of an outcrop analogue study

open access: yesGeothermal Energy, 2017
Minimizing exploration risk in deep geothermics is of great economic importance. Especially, knowledge about temperature and permeability of the reservoir is essential.

Structural Geology of the Škocjan Caves

open access: yesActa Carsologica, 2009
The Škocjan Caves are developed inside 300 m thick column of Cretaceous and Paleocene limestones. Most of the underground Reka River flows within the 130 m thick Lipica Formation (K2 4-5).

Structural Geology

open access: yesEos, Transactions American Geophysical Union, 2011
Structural geology and continental tectonics were ushered in to the modern quantitative age of geosciences with the arrival of the global plate tectonics paradigm (circa 1968), derived using new data from the oceans' depths, and John Ramsay's 1967 seminal work, Folding and Fracturing of Rocks.

Dilatant normal faulting in jointed cohesive rocks: a physical model study [PDF]

open access: yesSolid Earth, 2016
Dilatant faults often form in rocks containing pre-existing joints, but the effects of joints on fault segment linkage and fracture connectivity are not well understood.

Earthquake geology: science, society and critical facilities

open access: yesAnnals of Geophysics, 2014
Earthquake geology studies the effects, the mechanics and the impacts of earthquakes in the geological environment. Its role is also to decode the fault history, therefore its approach is fault specific and its outcomes are of decisive value for seismic ...

Volcanic stratigraphy and geological evolution of the Apan region, east-central sector of the Trans-Mexican Volcanic Belt [PDF]

open access: yesGeofísica Internacional, 2002
The Apan region, which straddles the central and eastern sectors of the Trans-Mexican Volcanic Belt (TMVB), was geologically shaped by interrelated, intermittent tectonism and volcanism.

Interpretation and Reconstruction of Depositional Environment and Petroleum Source Rock Using Outcrop Gamma-ray Log Spectrometry From the Huai Hin Lat Formation, Thailand

open access: yesFrontiers in Earth Science, 2021
Gamma ray logs are most useful in identifying subsurface lithology and interpreting depositional environments. This study highlights the use of outcrop gamma-ray logs along with outcrop observations and total organic carbon (TOC) analysis to provide the ...

ArcStereoNet: A New ArcGIS® Toolbox for Projection and Analysis of Meso- and Micro-Structural Data

open access: yesISPRS International Journal of Geo-Information, 2021
ArcStereoNet is a new ArcGIS® based toolbox for stereographic projections that we implement here using Python 2.7 programming language. The reason to develop another stereographic projection package arises from the recent use of Python as an exclusive ...

Evolution of a highly dilatant fault zone in the grabens of Canyonlands National Park, Utah, USA – integrating fieldwork, ground-penetrating radar and airborne imagery analysis [PDF]

open access: yesSolid Earth, 2015
The grabens of Canyonlands National Park are a young and active system of sub-parallel, arcuate grabens, whose evolution is the result of salt movement in the subsurface and a slight regional tilt of the faulted strata.
