Field Methods

Field work is a research area for the analysis of information in a laboratory. Field works consist of

  • informal iterviews
  • direct observation
  • participation in the life the group
  • collective discussions
  • self-analysis,
  • results from activities undertaken off- or on-line
  • life-histories.
Geologic Field Methods

Typical Field Works

  • Geological mapping
    • Structural mapping: identifying the locations of major rock units and the faults and folds that led to their placement there.
    • Stratigraphic mapping: pinpointing the locations of sedimentary facies (lithofacies and biofacies) or the mapping of isopachs of equal thickness of sedimentary rock
    • Surficial mapping: recording the locations of soils and surficial deposits
  • Surveying of topographic features
    • compilation of topographic maps
    • Work to understand change across landscapes, including:
      • Patterns of erosion and deposition
      • River-channel change through migration and avulsion
      • Hillslope processes
  • Subsurface mapping through geophysical methods
    • These methods include:
      • Shallow seismic surveys
      • Ground-penetrating radar
      • Aeromagnetic surveys
      • Electrical resistivity tomography
    • They aid in:
      • Hydrocarbon exploration
      • Finding groundwater
      • Locating buried archaeological artifacts
  • High-resolution stratigraphy
    • Measuring and describing stratigraphic sections on the surface
    • Well drilling and logging
  • Biogeochemistry and geomicrobiology
    • Collecting samples to:
      • determine biochemical pathways
      • identify new species of organisms
      • identify new chemical compounds
    • and to use these discoveries to:
      • understand early life on Earth and how it functioned and metabolized
      • find important compounds for use in pharmaceuticals
  • Paleontology: excavation of fossil material
    • For research into past life and evolution
    • For museums and education
  • Collection of samples for geochronology and thermochronology
  • Glaciology: measurement of characteristics of glaciers and their motion
