How to… A virtual classroom

measuring dip

A virtual classroom for Earth Scientists

The posts here provide an outline of method and theory for some of the basic tasks that geologists undertake in the field and lab. They are directed primarily at undergraduate geology students, but should be useful for anyone wanting a refresher. They are not encyclopedic descriptions – refer to the many fine textbooks, and journal papers for examples of more complex geological problems.

The How to… posts are more technical than those elsewhere on this website

The list of tasks will evolve. The emphasis initially is on stratigraphy, sedimentary and volcanic strata, sedimentary basins, geochemistry and mapping, but because sedimentary strata are commonly deformed, there is an obvious cross-over to structural analysis and tectonics.

How to…

Common structure – mapping problems

Describing sedimentary rocks

Lithofacies

Stratigraphy – sedimentology

Sequence stratigraphic principles

The polarizing microscope

Mineralogy of sandstones

Mineralogy of carbonates

Mineralogy of evaporites

Seds in outcrop

Volcanics in outcrop

Sedimentary basins

Hydrogeology

Soils and weathering

Planetary geology

Model are representational descriptions are written in different languages - diagrammatic, descriptive, mathematical, and conceptual. They commonly contain variables and dimensionless quantities that permit quantitative analysis of the physical systems the models represent.
