Introduction to Clastic or Carbonate Petrography

Audience

Geologists with a good basic understanding of geology who wish to further develop their skills in this area.

Content

The course covers the following aspects:

  • An introduction to clastic / carbonate petrography
  • Grain textures
  • Clastic / carbonate grain types (detrital mineralogy)
  • Classification
  • Diagenetic mineralogy
  • Porosity

Clastic Petrography covers:

  • Thin section preparation
  • Staining techniques
  • Thin section petrography basics
  • Identification of grains
  • Texture (grain size, sorting, shape and fabric)
  • Point counting (modal) analysis
  • Classification of sandstones
  • Packing, porosity and permeability
  • Factors controlling diagenesis
  • Diagenetic processes in relation to sandstone porosity
  • Porosity enhancement
  • Environmental indicators and provenance

Carbonate Petrography covers:

  • Lithology
  • Depositional texture (Dunham classification)
  • Grain size and texture (sorting, roundness, grain contacts)
  • Present versus original rock components (e.g. grain types, mud, fossils, cements, pores, diagenetic minerals)
  • Pore types and cements (identification, distribution and relationships)
  • Diagenesis and advanced petrographic techniques
