The document provides a student's feedback summary from a field mapping exercise. It includes: - An overall grade of B1, with strengths in geological thinking and room for improvement in time management and neatness. - Feedback on specific mapped features, praising the student's geological problem-solving skills and noting areas like linking sketches more clearly. - The student expresses pleasure in showing potential and a desire to improve data collection and presentation in future fieldwork.

4. Feedback Summary
Grade: 17/22 = B1, strong 2:1, 1 grade
point below 1st
Strengths:
• Geological thinking and
understanding as shown by
differentiation of rock units, boundary
placement, and interaction of
multiple faulting events.
Areas for improvement:
• Time management in field and when
inking in map.
• Neatness and presentation under
time-limited conditions.
Personal thoughts:
• I am very pleased to see that I have
shown strong potential for geological
problem solving. I look forward to the
challenge of future fieldwork where I
will work hard to improve data
quantity and presentation quality.

5. Areas of Interest
Including brief personal
analysis based on feedback
and discussions with lectures.

6. Inferred Isograd and Polymetamorphism Sketch
Strengths:
• Isograd distance between outcrops is
weighted based on estimated
metamorphic grades.
• Isograd is curved since topography was
considered.
• Well-plotted, relevant measurements.
Suggested improvements:
• Link sketch to map location more
definitively.
• Add sketch title and clearly label what
the sketch is (i.e. Kyanite crystal with
preserved reaction texture of partial
phase change to Andalusite due to
contact metamorphism overprint)
• Clearer definition of significance of the
preservation of the reaction texture.

7. Transition Unit and Large-scale Boudinage
Strengths:
• Use of a transition unit to take into account
large area of interbedding between Pelite and
Marl units. Not used by many other students.
• Boundaries consider unit dip and topography.
• Well-spaced, relevant measurements (though
readability is still an issue)
Suggested improvements:
• Brief explanation of significances of boudinage.
• Label viewpoint for sketch (i.e. plan view).
• General neatness of pen-work.

8. Igneous Intrusions and Complex Faulting
Strengths:
• Recognition of two separate dyke intrusions and
their displacement across multiple faults.
• Conveying the relative age of the mylonite fault
by inferring displacement from cross-cutting
younger faults on the beach.
• Use of mappable Quartzite unit within the Pelite
unit to infer fault displacement.
• Intrusions, boundaries and faults consider dip
and topography.
Suggested improvements:
• Perhaps overzealous with connecting faults to
the East (screen right) of the mylonite fault.
• Take and display on more measurements e.g.
more measurements for dyke intrusions and
Quartzite unit.
• Spacing and neatness of measurements.

9. Faults Cross-cutting Folds, with Sketch
Strengths:
• Identification of three possible phases of faulting.
• Continuation of fault up the hillside, following observed breaks in topography.
• Measurement of S and Z type parasitic folds.
• Mapped displacement of faults through fold structures.
• Attempted to convey the complex interaction of folds and multiple phases of faulting.
Suggested improvements:
• Link sketch to area on map and add title.
• Add a written explanation of each step in diagram for clarity.
• Consider different diagram style or use of multiple colours.
• Neatness of pen-work, particularly with red pen.
