Geological modeling or geomodeling is the creation of representations or numerical equivalents of parts of the Earth's crust, both on and beneath its surface.

Geological modeling (geomodelling) is an applied science that involves creating computerized representations of parts of the Earth's crust based on geophysical and geological observations.

Geological modeling (geomodeling) is associated with the concept of a comprehensive Earth model (an interdisciplinary, interoperable, and updatable knowledge base about the Earth's subsurface). Geological modeling (geomodeling) is used for managing natural resources, identifying natural hazards, and quantitatively assessing geological processes, primarily applied to oil and gas fields, groundwater aquifers, and mineral deposits.

What is geological modelling (geomodelling) used for:

  • Reliable geological data and a well-constructed geological model form the basis for accurate mineral resource estimation, which in turn determines financial and operational decisions throughout the entire value chain of the project.
  • Geological models help determine the volume and concentration of valuable minerals, which are subject to economic constraints for assessing the economic value of mineralization.
  • Geological models encompass all aspects controlling mineralization at the deposit, including factors influencing geotechnical stability, geometallurgical recovery, and waste characterization.
  • Advancements in geological modeling, particularly implicit modeling, have allowed geologists to visualize and model geology in 3D rather than using the traditional 2D sectional approach. This enables quick incorporation of more extensive datasets into the model.
  • Investing time and effort in geological modeling during the early stages reduces geological uncertainty in the project and leads to cost savings on drilling for expansion and grade control and reduces the time needed to update future geological models with new data.
  • Three-dimensional geological models characterize the structure of rock formations and deposits in the subsurface, providing sophisticated tools for a deeper understanding of geology. They are used for decision-making and supporting comprehensive analyses of soil conditions, groundwater systems, resource assessment, and reserves estimation. 3D modeling yields reliable results and increased information, making it essential for practical applications, using the three-dimensional spatial structure of each layer as the boundary for modeling.

Advantages of Using Remote Sensing Data

Modern remote sensing tools include LiDAR and digital elevation models, high-resolution optical remote sensing, thermal remote sensing, hyperspectral remote sensing, microwave and SAR remote sensing, as well as remote sensing using historical aerial imagers or archival images, covering a period from centuries ago to the present. Thus, remote sensing allows us to perceive the Earth beyond our visual capabilities and overcome the temporal and spatial constraints of ground observations.

Evidential (empirical) advantages of remote sensing data include the following:

  • Digital Elevation Model (DEM) based on Light Detection and Ranging (LiDAR), which is directly related to the bare earth surface, is successfully used for mapping topographic features with corresponding scale and accuracy and facilitates the measurement of fine topographic details.
  • Three-dimensional (3D) multiparametric geological modeling and microanalysis are used to discuss molybdenite mineralization and oxidation processes during the supergene stage.
  • Remote sensing can be used for layer-by-layer modeling of the spatial variability characteristics of internal geological properties of Quaternary unconsolidated sediments, such as lithology, porosity, and water content, using the three-dimensional spatial framework of each sediment as the basis.
  • It simulates how experts in the field interpret geological structures and allows creating models directly based on interpretation tasks, avoiding the drawbacks of separate modeling stages.
  • The sketch-based modeling system is based on standard annotations of two-dimensional geological maps and interpretative sketches of geologists, which is not always feasible in the field.
  • Specific geological rules and constraints are applied and evaluated in the sketch-based modeling process to ensure the construction of a reliable 3D geological model.
  • Integrative 3D model of short-wave infrared (SWIR) hyperspectral mapping and digital elevation model (DEM) based on unmanned aerial vehicles (UAVs) for revealing carbonate rocks.
  • A new 3D geological modeling method is mainly applied in the geological field and has made new progress in integrating heterogeneous geological data from multiple sources, large-scale high-precision modeling, geological grid subdivision, attribute modeling, image fusion in remote sensing, and other aspects.

FAQ

Geological modeling (geomodelling) for rapid creation of reliable volumetric models and basic resource estimation includes the following components:

  • Wireframing of spatial bodies and surfaces. This involves a set of semi-automatic and interactive 3D tools for creating, modifying, displaying, and evaluating closed and topographic wireframe models.
  • Intelligent mineral exploration based on machine learning algorithms and 3D modeling.
  • Geostatistical analysis of deposits includes tools for variogram construction, analysis, and interactive fitting of models. It also involves cross-validation of selected variogram models, multiple types of 3D kriging, resource estimation, and more.
  • Deposits modeling provides capabilities for constructing, viewing, evaluating, and editing block models of deposits. Metal grade interpolation and other indicators are performed using traditional and geostatistical methods. Visualization, interpretation, and modeling of project data (including Big Data) are also supported.
Accounting for the spatial position of the main boundaries of the geologic formation, including the effects of faulting, folding, and erosion. Therefore, the main rock stratigraphic lines are subdivided into layers of cells with different geometry with respect to bounding surfaces (parallel to the top, parallel to the base, proportional). The maximum size of rock cells is determined by the minimum size of rock composition objects to be resolved. Sometimes maximum resolution is required.
An important part of geological modeling (geomodelling) is related to geostatistics. To represent observed data, often not on a regular grid, we must use certain interpolation techniques. To reproduce more realistic spatial variability and to help estimate the spatial uncertainty between geologic data, geostatistical modeling based on variograms, training images, or parametric geologic objects is often used.
is associated with the concept of a comprehensive Earth model
Geological modeling involves creating three-dimensional representations of subsurface geological structures. Remote sensing data contributes to geomodeling by providing valuable information about surface geology, terrain characteristics, and environmental factors. This data aids in understanding the geological features that influence subsurface structures.
Remote sensing sensors like LIDAR capture high-resolution elevation data, assisting in geomodeling by providing accurate topographic information. Hyperspectral imaging captures a wide range of wavelengths, helping identify mineral compositions and geological variations. Both sensors find applications in geological mapping, structural analysis, and resource exploration.
Temporal analysis of remote sensing data is crucial in geological modeling for tracking changes over time. It helps monitor geological features, such as erosion, land subsidence, or vegetation growth, providing insights into dynamic processes influencing the landscape and subsurface structures.
Integrating remote sensing data with GIS technology enhances geological modeling by providing a spatial context for analysis. This integration supports decision-making in resource exploration and environmental management by allowing geologists to map and analyze geological features, plan exploration activities, and assess environmental impacts based on comprehensive geospatial information.
Geological modeling using remote sensing data benefits industries by improving resource exploration accuracy, optimizing mining operations, and assessing environmental risks. Challenges may include data interpretation complexities, calibration issues, and the need for ground validation to ensure the accuracy of geological models derived from remote sensing data.
