We describe how we use models of mantle dynamics to understand and test the controls and effects of plate tectonics, such as ocean basin volume, magma production and the formation of natural resources. Numerical modeling and geological ground-truthing were incorporated to test the hypothesis that vertical motion of the Australian continental plate, as observed from sediments deposited during a ...

Projections of climate change impact are associated with a cascade of uncertainties including in CO2 emission scenarios, climate models, downscaling and impact models. The relative importance of the individual uncertainty sources is expected to depend on several factors including the quantity that is projected. In the present study the impacts of climate model uncertainty and geological model u...

The technique of 3D geological modeling (3DGM) is an effective tool for representing complex geological objects. In order to improve the accuracy of geological models applied in numerical simulation methods such as finite elements and finite differences, we can use 3DGM as a modeling tool. To do this, however, 3DGMmust provide the ability to model geological and artificial objects in a unified ...

Uncertainties are common in 3-D geological models, due to different causes. We address here uncertainties introduced by input data quality and incomplete knowledge with a stochastic approach. Instead of only one model, we obtain a set of probable realizations. We then apply information entropy to analyze and visualize uncertainties in discretized representations of the models. In a simple examp...

At present no company develops oil and gas fields without constructing geologic and hydrodynamic models. This is due in particular to the fact that recently the emphasis in design, planning and monitoring has shifted to overdissected and low-permeability reservoirs. To assess economic efficiency and optimal placement of wells and to predict hydrocarbon production levels, it is important to have...

Two-dimensional GIS are extensively used in geology to create, analyse, and interpret geological map models. However, these systems are unable to represent the Earth’s subsurface in three spatial dimensions. The objective of this article is to overcome this deficiency and to provide a general framework for a 3d GIS. The presented approach is based on existing 3d geomodelling theory and software...

Geoaesthetics is the project of making aesthetic sense of nature through geological phenomena. The aesthetic appreciation of nature has recently become urgent because of the serious influence of the natural environment on human beings. The author’s geoaesthetical research is categorized into three problems: art in geology or geology in the arts as the close relationship between art and geology,...
