3D geological models become increasingly important and popular recently. But it is too difficult to share the models because of different models come from different modeling software. It is urgent to solve the problem for the unification of data management. Based on it, the paper explains basic construction and architecture if GeoSciML to discuss how to take advantage of this standard and defin...

Hf isotope ratios measured in igneous zircon are controlled by magmatic source, which may be linked to tectonic setting. Over the 200-500 Myr periodicity of the supercontinent cycle - the principal geological phenomenon controlling prevailing global tectonic style - juvenile Hf signals, i.e. most radiogenic, are typically measured in zircon from granites formed in arc settings (crustal growth),...

Geological disaster causes loss of lives and damage to man-made and natural stuctures. In this paper, a coupling method with optimal combination weighing law and extension model was established. Based on dynamic impact factors such as forest coverage, annual average rainfall, topography and gemorphogy, geologic structure, and type of rock and soil, the amount of disaster points and human engine...

In this paper we present a new method for Boolean operations (intersection, union and difference) of triangulated solids, and its applications in three-dimensional (3D) computerized geological modelling (3DGM). This method is adapted to arbitrary (convex or concave), close geological solids. Three major steps are included in this method: (1) Calculate intersection points between triangles. Our ...

The Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS) initiated a two-year regional pilot survey in 2007 to develop, test, and validate tools and approaches to assess the condition of northern Gulf of Mexico (GOM) coastal wetlands. Sampling sites were selected from estuarine and palustrine wetland areas with herbaceous, forested, and shrub/scrub habitats delineated by the ...

History matching forms an integral part of the reservoir modeling work-flow process. Despite the existence of many history matching tools, the integration of production data with seismic and geological continuity data remains a challenge. Geostatistical tools exists for integrating large scale seismic and fine scale well/core data. A general framework for integrating production data with divers...

In this article we present a new method for seismic image restoration. When observed, a seismic image is the result of an initial deposit system that has been transformed by a set of successive geological deformations (flexures, fault slip, etc) that occurred over a large period of time. The goal of seismic restoration consists in inverting the deformations to provide a resulting image that dep...

Two geostatistical methods for history matching are presented. Both rely on the sequential simulation principle for generating geologically sound realizations. The first method relies on perturbing the sequential simulation through the perturbation of the conditional distribution models; the second method relies on the perturbation of random numbers. We show that both approaches are general in ...

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,...

Three-dimensional (3D) modelling of geological body is an important issue of 3D GIS and 3D Geosciences Modelling, and one of the key technologies of digital mine. GTP model and its components are introduced in this paper. According to the relations between chronolith and rock attribute comprehensively, the modelling region, system, series, group and rock characteristics(RC) are regard as the sc...
