Based on the precipitating factors of geological disasters in complex mountainous regions, this paper took geological disaster distribution, seismic intensity, fracture, engineering petrofabric, river distance, slope and precipitation as the risk indicators of geological disasters. Next, a mathematical model was established by using the analytical hierarchy process. The weight of above seven ri...

It is related to the realization of the benefit of state-owned resources and the long retainable development of the country to evaluate the mining property rights to improve the using rate of the mineral resources. Guided by the principle of prospective return, a method for evaluating geological potential value was put forward which emphasized on the valuation of geological techniques. A coeffi...

Spatial pattern is crucial to geoscience. It enables us to compare the observed properties of objects and explain their spatial relationships, correlation and distribution in terms of the geological circumstances and processes that formed them. Digital cartography and the spatial model provide computer support for looking at objects and properties in their spatial context. Transformations enabl...

We present the development of a reactive transport model and demonstrate its use to model the geochemical evolution of carbonate-rich pore networks within the context of geological carbon sequestration. The model’s architecture is explained, as well as the equations used to model the transport of species and the kinetic and equilibrium equations used for reaction and speciation. We present mode...

Three-dimensional (3D) raster are simple representations, which have long been used for modelling continuous phenomena such as geological and medical objects. However, they can result in large data sets when high resolution is used, which poses challenges to algorithms for vector-to-raster conversion and data storage. This paper presents a research towards developing generic techniques and tool...

1.1 The evidence for the Lower and Middle Palaeolithic in Northamptonshire has recently been summarised and briefly reviewed as part of the English Heritage sponsored English Rivers Palaeolithic Project (ERPP) (Wessex Archaeology, 1996). This paper has been prepared as part of the East Midlands Regional Research Frameworks Project to provide a brief statement of the current state of knowledge f...

Introduction The special issue of this journal (Nov. 2000) that was devoted to “Some Great Ideas for Geoscience Courses,” included nine ideas under the heading “Earth materials.” Six of those papers involved classification (Thomas and Thomas, 2000; Dowse, 2000; Reynolds and Semken, 2000; Harper, 2000; Christman, 2000; Niemitz, 2000). Classification of rocks and minerals is obviously a necessary...

Geological, geophysical and hydrological surveys were performed in an area between Lecce to the North and Otranto to the South on the Lower Adriatic coast of Italy in order to verify the “state of health” of the ground water in the deep aquifer, which is characterised by Mesozoic carbonatic formations and is permeable due to fracturing and karstic phenomena. This area was chosen because it is h...

The aim of this study is to characterize and find the location of geological boundaries in different wells across a reservoir. Automatic detection of the geological boundaries can facilitate the matching of the stratigraphic layers in a reservoir and finally can lead to a correct reservoir rock characterization. Nowadays, the well-to-well correlation with the aim of finding the geological l...
