Geological Cartography
Objectives
Provide methods and knowledge that enable the student to perform a coherent cartographic geological survey on any terrain and geological setting within the various professional-technical-scientific contexts.
The student must acquire skills to carry out geological surveys at various scales in a real situation; to produce a geological map on a topographical surface, tracing the geological limits, and the geometry of tectonic structures, describing the lithology and integrating it into the stratigraphy, and finally, incorporating all the information transposing it to a field report.

Teaching method
(A) First theoretical classes preparing students for field work, using PPT projections and published geological maps.
(B) Geological mapping in the field, based on 1/10000 topographic maps and making photointerpretation.
Also some laboratory classes of analysis of geologically complex maps will be done, where students will interpret them and make geological profiles.
Evaluation method
Students must be present in at least 2/3 of TP classes and field classes.
Final classification (FC):
A - Attendance per class
B - Participation. This criterion considers the student''s participation and performance in classes (continuous training) and the diligence demonstrated during fieldwork. (-1 point to Disturbing Participation);
C - Conducting Formative Knowledge Tests in class.
D - Geological Report after the field work. Carrying out a field report (production of a geological map and subsequent report). The quality of the report is measured through: a) data collection and processing requirements; b) the quality of the Map and the accuracy of the geological cross-sections produced; c) the result of the proposed practical exercise. d) the relevance and graphic quality of the figures (schemes and field photos), e) the quality of the discussion and geological history. (Rating 0 to 20 values).

Subject matter
The academic course contents will be developed in four stages:
- Stage 1. Introduction of theoretical concepts of cartography and analysis / interpretation of maps at different scales with the production of geological profiles.
- Stage 2. In the classroom and in field context (near the college) the student is trained to use the compass to represent the outcrops in the field book, to mark geological boundaries and to trace the attitude of planes and linear structures.
- Stage 3. Field component. During five days the student will have to conduct a geological survey at scale 1/10000.
- Stage 4. Production of a field report, respecting the model proposed by the teacher.
