Abstract

Spatial Mapping of Strain Patterns Using GIS
Track: Mining and Geosciences
Authors: Roy Miller III

Assuming homogeneity for strain analysis limits the geologist on interpreting the tectonic history of a feature properly. GIS can be used to quantify and map heterogeneous strain. The thin sections of öoids were digitized and the orientation and strain magnitude (major/minor axes) were used to map it. Open GeoDA was used to determine spatial statistics. This project is one of few studies that use GIS on microscopic features, but this can aid with interpreting tectonic processes more vividly.
