Siccar Point Field Excursion Preview

Field sketch of Hutton's Unconformity

On all field excursions you will be asked to draw field sketches to illustrate the relationships between rock formations. Keep the following points in mind:

  • Decide whether the sketch is to be a map, a view or a cross-section.

  • Draw a sufficiently good sketch to photocopy and paste into a report.

  • Make the sketch resonably large, say 8 to 12cm wide.

  • Pick out the main features with bold lines (use a HB or 2B pencil).

  • Give the sketch a definite title. For example View of...

  • Give an orientation. For example View of ... looking North.

  • Include a scale, typically a line terminated with arrows and labelled with its length in metres.

This is Siccar Point on a good day - please sketch the relationship between the major rock types and make sure you include the orientation of the layering in each. Help: [1], [2], [3], [Example]
