Training objectives
- The purpose of the course is to provide students with the following skills:
• knowledge for reading and interpretation of a geological map; basic techniques for mapping (position finding on maps, description and interpretation of outcrops, tracking limits of stratigraphic and tectonic structures);
• skills to prepare a geological map in all its components (geological map, geological cross-sections, stratigraphic schemes, legend and geological report). Prerequisites
- It is essential that the student has learned well the topics discussed in the courses Geology I and has followed the courses of Physical Geography and Geomorphology and the Laboratory of Stratigraphy and Sedimentology.
Course programme
- The course consists of 18 credits: 4 theory + 2 laboratories + 8 exercise.
Introduction to the course: Geological Mapping as an interdisciplinary technique and approach. Organisation of the course, class lectures, field excursions and field course. Final examination. Field Equipment: hammers and chisels, lens, compasses and clinometers, handlenses, map Cases, Field notebooks, scales, protractors, pencils and erasers, acid bottles, Global Positioning System (GPS), field clothing.
Cartography: Notions of Topography, classification of geographic charts. The IGM cartography as Italian standard for the topographic maps: Different IGM products (1:100.000; 1:50.000; 1:25.000). Geographic coordinates and Metric Grids. Coordinates of a point on a IGM’ charts. The CTR. The webgis and the national and regional online cartographic sites. The LIDAR, the DTM, aerial photographs and orthophotos. The concept of mapping at different scale. Construction of topographic profiles. Three-dimensional visualization of the topography. Recognition of the ridge line and the watershed.
Geological mapping and stratum contours: Structure of a Geological maps. Legend, profiles and patterns. Stratigraphic and chronostratigraphic schemes. Orientation of a plane in space; Defining direction, dipping and inclination. Introduction to stratimetry. Marking the geological boundaries on topographical maps. Layers dip slope (more or less inclined), anti- dip slope, horizontal and vertical. Real and apparent tilt angle. Interaction between formational boundaries, faults or folds and the topographic surface, intersections of structure contours and topographic contours. Recognition of thickness. Construction of geological cross-sections. Reading and interpretation of geological maps. Reconstruction and interpretation and relative dating of structures and events through reading a geological map.
Introduction to the GIS and questions related to the digitization of geological maps. Georeferencing topo sheet and scanned maps. Tracing of polygons and lines in GIS environment. The open source programs.
Methods of geological mapping: The graphic techniques for the transport and interpretation of geological data on maps. Organization of the survey, literature search, acquisition of topographic and geological bases. The drafting of a geological report: text organization, thematic maps, tables and attachments. The CARG procedure.
Geological field camp: The geological survey camp will be held in the Dolomites and will last 8-10 days, including 2-3 days dedicated to the introduction to the stratigraphic succession of the Dolomites and the remainder dedicated to the mapping of the areas assigned by the teacher. Each student will have to perform the geological survey (at 1: 10,000 scale) of a mountainous area of about 6/8 square kilometres. Each student will have to produce an outcrop’ map and an interpreted geological map, complete with geological cross-sections. The final report must include: the geological map of the area, geological cross-sections, the description of the lithostratigraphic units (including deposits and forms of the Quaternary), the main tectonic structures and a brief summary of the geological evolution of the area. Didactic methods
- Theoretical/practical lessons.
Part of the course will be in the field Learning assessment procedures
- The examination consists of three parts:
1) written test at the end of the course: the resolution of a geological mapping problem (geological cross-section);
2) practical part: it consists of producing a geological map through the geological survey of a given area. The geological map must be accompanied by an explanatory report with imagery, stratigraphic schemes, stratigraphic series and at least 3 cross-sections including 2 intersecting.
3) Oral part: is the discussion of what made during previous tests.
The final course results, will be the average of the written exam (geological mapping problem) and oral part (discussion of cartographic documents and report). Reference texts
