Mesh Generation for Geological Applications: Los Alamos National Laboratory
Geologic applications for computational grids produced with LaGriT are utilized for modeling subsurface porous flow and reactive chemical transport by finite element and finite difference methods. LaGriT is also used as the first step in quality analysis of geometric data. The grid may be the first time data is visualized and errors may be seen. Projects in which LaGriT is utilized include: Yucca Mountain Site Characterization Project (YMP), Environmental Restoration at Los Alamos and Savannah River, Oil and Gas Reservoir Modeling, Semiconductor Design Modeling, and High Speed Hydrodynamics.
Three-Dimensional Geological Model of Manitoba
Gaywood Matile and Greg Keller of Manitoba Geological Survey have a new Web site up and running to make available some of the 3D work that was presented in Denver. It is the first in a series of phases. Part of it works o nly with Internet Explorer. Remember to scroll down for instructions on the 2D view page. Comments are welcome!
USGS 3D Geologic Mapping In East-Central Illinois
Through a collaborative effort between the Illinois State Geological Survey (ISGS) and the U.S. Geological Survey (USGS), the surficial, glacial deposits have been mapped using newly developed 3-D mapping methods.
3D Model of the United Kingdom
This 3D model of subsurface Britain was constructed from the 1:625,000 scale geological map, drilling, and deep geophysical investigations. It represents ten layers from the Moho (at a depth of around 30KM) up to the base of Quaternary deposits (at a depth of a few meters). Despite its national coverage, the model is consistent with the most detailed interpretations of the shallow geology.
The Pacific Northwest Center for Geologic Studies
The Pacific Northwest Center for Geologic Mapping Studies at the Department of Earth and Space Sciences, University of Washington (formerly the Seattle-Area Geologic Mapping Project), develops geologic datasets and maps to support hazard asessments and land use applications for the Puget Lowland.
Systematic modelling of the shallow subsurface in the British Geological Survey
This page describes the methodology and software tool GSI3D used to systematically model the shallow subsurface (upper hundreds of metres) at resolutions equivalent to our 1:50,000 and 1:10,000.
