Topological relationships between geological objects are of great interest in the process of mining and petroleum exploration. Indeed, adjacency, inclusion and intersection are common relationships between geological objects such as faults, geological units, fractures, reservoirs... However, in the context of 3D modeling, actual geometric data structures used to store objects of interest are no...
— The geological surveying presently uses methods and tools for the computer modeling of 3D-structures of the geographical subsurface and geotechnical characterization as well as the application of geoinformation systems for management and analysis of spatial data, and their cartographic presentation. The objectives of this paper are to present a 3D geological surface model of Latur district in...
Building a 3D geological model from field and subsurface data is a typical task in geological studies involving natural resource evaluation and hazard assessment. However, there is quite often a gap between research papers presenting case studies or specific innovations in 3D modeling and the objectives of a typical class in 3D structural modeling, as more and more is implemented at universitie...
Three-dimensional modeling of geological bodies is a useful tool for multiple applications. Such tasks are usually accomplished starting from fieldcollected data, which typically suffer from intrinsic limitations such as accessibility constraints and punctuality of data collected. In this work, we explore the reliability of photo-geological mapping from interpretation of aerial photographs in p...
In the context of deep geological disposal of high level radioactive wastes, the French National Radioactive Waste Management Agency (Andra) has conducted an extensive characterization of the Callovo-Oxfordian argillaceous rock and surrounding formations in the Eastern Paris Basin. For such characterization, a detailed 3D geological model is needed. This paper shows the procedure used for build...
This paper addresses the application of integrated chargeability and resistivity method and grade data in modeling and evaluation of copper deposits. We argue that the relationship between IP, Rs and grade data may be used for modeling and reserve estimation and tested this argument for Sarbisheh copper deposit that is located in eastern Iran. Geology and mineralization situation of Sarbisheh d...
Combining different sources of information about the subsurface is an inherent challenge in process making realistic geological and hydrostratigraphic models. Often available hydrological data from boreholes or outcrops are sparse modeling supplemented spatially with geophysical to obtain a better understanding 3D lithological, structural, relations study area. In traditional modeling, modeler ...
Fault modeling is a very important step in making an accurate and reliable 3D geological model. Typical existing methods demand enough fault data to be able to construct complex fault models, however, it is well known that the available fault data are generally sparse and undersampled. In this paper, we propose a workflow of fault modeling, which can integrate multi-source data to construct fau...
During numerical simulation of geotechnical engineering, due to the complex engineering geological condition, the simplified geologic model is usually adopted. However, the accuracy and reliability of calculating result are directly influenced by characteristic of model. The 3D geologic model can better reflect the actual geological condition. The paper presents a new and practical modeling met...
