Introduction to Clastic or Carbonate Petrography


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


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

Learning Objectives

The aim of the course is to give the participant the necessary skills to undertake clastic and carbonate petrography.
