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-pratical 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 previous photointerpretation.
Laboratory classes of analysis of geologically complex maps will be done, where students will interpret them and make geological profiles.
The aim is to focus on thematic Geological Cartography, with special emphasis on the application to georesources and metallogeny, to the different deformation boundaries analyzed considering the structural character evidenced at various scales and to neotectonics, an aspect that is decisive for the practice of a Geological Engineer.
Evaluation method
The Final grade (FG) is obtained through the following weighting coefficient:
FG = 10%A*1 + 20%B*2 + 30%C*3 + 40%D where D cannot be
*1 – Max=13 points (20 points)
*2 – Max=13 points (20 points)
*3 – Average evaluation considering the sum of the 13 classes
A – Attendance per class (Absence - 0 points; Presence - 1 point).
The attendance criterion implies the presence at least 2/3 of the TP (9 classes). The attendance at field classes is mandatory.
B – Participation in classes. This criterion considers the student''s participation and performance in classes, the diligence demonstrated during fieldwork. -1 - disturbing; 0; 1 - active participation. “Active participation” is understood as the demonstration of interest, dedication, diligence and quality of observations during classes and during the field geological survey.
C – Carrying out Formative Knowledge Tests in class (includes a mini-test).
D - Preparation of field report (production of geological map and subsequent report). The quality of the report is measured through a) compliance with the template and organization (index) proposed by the teacher; b) requirement for data collection and processing; c) the quality of the Map and accuracy of the geological profiles produced; d) the result of the proposed practical exercise. e) the relevance and graphic quality of the figures (diagrams and field photos), f) the quality of the discussion and geological history. (Grading 0 to 20 values).
Subject matter
The academic course contents will be developed in four stages:
- Stage 1. Introduction of theoretical-Practical 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 the student is trained to represent the outcrops, to mark geological limits and to trace the attitude of planes and linear structures.
- Stage 3. Field component. For four 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.
