Cellular Automata Approaches for Simulating Rheology of Complex Geological Phenomena
1998Cellular Automata (CA) permit sometime an alternative method to differential equations for modelling and simulating some kind of complex systems, which can be described in terms of local interactions of their constituent parts. Typical application fields of CA are microscopic physical phenomena with elementary automata, which have few states and a ...

Drawing parallels: Modelling geological phenomena using constraint satisfaction
Journal of Structural Geology, 2010Abstract This paper gives insight into the transition between the different folding-types seen in nature. Using constraint satisfaction and optimization to study least energy solutions of an elastic, frictional model for concentric parallel folding, kink band waveshapes resulting from the same model are discovered. Simplifying the concentric parallel

Numerical modelling of geological phenomena in karst regions
2001This article gives an overview of geophysical methods that can be used for the investigation in karst regions. Representative geological profiles and some geomechanical parameters can be estimated on the basis of geophysical measurements. Numerical modelling was performed in order to study the subsurface processes that lead to the formation of ...

Correlating magnetic field polarity changes with geologic phenomena
Geology, 1985Two reported correlations are discussed in this paper: the first claims a correlation between magnetic polarity and oxidation state of igneous rocks, and the second claims that the Hawaiian hot-spot chain exhibits a significantly dominant normal-polarity bias.

More is different: On the emergence of collective phenomena in fractured geological media
2023Fractures such as joints and faults are widely present in crustal rocks. These discontinuity structures often form complex networks and dominate the bulk behaviour of geological media. Thus, understanding how fracture networks affect multiphysical processes and phenomena in subsurface rock formations is highly relevant to many geoenergy and ...

EMERGENT CHEMO-HYDRO-MECHANICAL PHENOMENA IN CARBON GEOLOGICAL STORAGE
2011The combustion of fossil fuels produces carbon dioxide (CO2). Carbon capture and geological storage (CCS) has been proposed to reduce the emission of greenhouse gases to the atmosphere. The properties of CO2 depend on pressure and temperature: it can be found as a gas, liquid, or supercritical, and it reacts with water to produce carbonic acid lowering

ENGINEERING PROTECTION OF HIGHWAYS FROM DANGEROUS GEOLOGICAL PHENOMENA
Crisis Management and TechnologiesThe article is devoted to road safety and engineering protection issues. Engineering protection of highways is a set of measures that can ensure their safe exploitation. Commonly, the engineering service is structured within three stages: slope stability analysis, detailed examination of hazardous road sections and implementation of complex engineering

On the Basin of the Firth of Forth, and some of its Geological Phenomena
Proceedings of the Royal Society of EdinburghI. An account was given of the dimensions of the estuary, in respect of length, width, and depth; and also of the general direction of the axis of the estuary.II. It was next shown that the formation of the estuary was probably due to the great geological fractures and dislocations which had taken place in this part of Scotland, inasmuch as the ...
