Description including Unit Aims

The overarching aim of this unit is for students to learn how to acquire, process and visualise spatial data at a range of scales with applications to all fields of Earth Sciences. There is a focus on geological expressions of dynamic tectonic regimes, including the analysis of active stress and strain fields, geomechanics, 3-D interpretation of geological maps, geospatial data analysis in GIS and state-of-the-art satellite remote sensing.

  1. Plate tectonic framework including the scientific evidence for plate tectonics, the use of Euler poles for understanding current and past plate motions, and the link to earthquakes and faults in active tectonic regions.
  2. Geomechanics covering the fundamental principles of stress, strain and rock mechanics and the use of Mohr circles to understand fault structures.
  3. Geological Mapping including the interpretation of subsurface geology and structures, visualising 3-D structures through constructing cross sections, and understanding the geological history of an area.
  4. Geological Information Systems (GIS) focussing on analysing geospatial data, including an introduction to digital data structures and ArcGIS.
  5. Satellite Imagery introducing the principles of remote sensing, the capabilities of state-of-the-art satellite systems and applications across the Earth Sciences.

As this is an integrated unit, each session starts with a short introductory lecture covering fundamental principles, followed by practical exercises. This gives students the opportunity to learn through manipulating real-world data and problem solving.

Intended Learning Outcomes

On successful completion of the unit you will be able to:

  • understand the evidence underpinning the theory of plate tectonics and use of relative plate motions to understand modern plate boundaries and reconstruct past positions of plates
  • use seismic and geodetic data to describe the tectonics of actively deforming regions and understand the relationship to faulting and earthquake activity.
  • describe the principles of stress and strain analysis and show how these can be applied in understanding rock deformation;
  • apply Mohr circle analysis to determine the state of stress of a rock and calculate the stress required for brittle failure;
  • understand the difference between brittle and ductile rheological regimes and the implications for crustal deformation and global tectonics
  • interpret 3-D structures using 2-D geological maps and interpret the causal deformation process and tectonic regime in which they formed;
  • understand the physics of remote sensing, and the application of different parts of the electromagnetic spectrum.
  • describe Earth Observation systems as a function of spatial and temporal resolution and relate their spectral sensitivity to different targets
  • understand the principles of GIS, including the underpinning data structures (objects, including points, lines and polygons; fields, raster, vector) and their relationship to real world examples
  • use industry standard software (ArcGIS and ENVI) to interrogate and process digital images

Teaching Information

The unit will be taught through a combination of

  • asynchronous online materials and, if subsequently possible, synchronous face-to-face lectures
  • synchronous office hours
  • asynchronous directed individual formative activities and exercises
  • guided, structured reading
  • practical work in the laboratory

Students who either begin or continue their studies in an online mode may be required to complete practical work, or alternative activities in person, either during the academic year 2020/21 or subsequently, in order to meet the intended learning outcomes for the unit, prepare them for subsequent units or to satisfy accreditation requirements.

Assessment Information

100% coursework

Coursework will comprise:

  • a mapping report - a five page written desciption of the field area and a digital map and cross section derived from fieldwork during EASC20029
  • 2 practical submissions.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EASC20045).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
