Deformation Processes and Maps

Description

This module represents a progression from Geological structures and tectonics in semester 1, where advanced map interpretation and more complex aspects of structural geology such as stress and strain and strain analysis are introduced.

Thus topics build on elementary structural geology with a focus on geological map interpretation and prepare students for year 2 (level I) Continental Deformation, the Pembrokeshire field course and independent mapping projects.

Geological maps are a 2D representation of 3D geology – the intersection of geological structures with the Earth’s surface.

At one level, they are a means of recording those rock types that crop out at the surface and of inferring their presence in areas of poor exposure. However, they also represent a powerful means of interpreting the geological history of an area, and constitute scientific hypotheses in their own right.

The ability to interpret geological maps in three dimensions, or four dimensions if one considers the time component, is thus a fundamental component of being a geologist.

In addition this module considers the deformation processes that result in complex geological structures and focuses on stress, strain and rheology as a means to understand this.

There are therefore experiments that demonstrate and test ideas about this included alongside map interpretation

Delivery

  • 30 hours (30-40 minute lecture followed by practical class each week)

Assessment

  • 100% coursework: Coursework folder includes a number of class exercises plus two independent map exercises. A check list is provided during term

Opportunities for formative assessment include advice and feedback during class from staff and demonstrators.

One piece of work is handed in for detailed formative feedback. Any work can be sent to the module leader for advice or feedback during term time.
