Learning objectives
Preparare gli Studenti al rilevamento geologico ed alla redazione, elaborazione, lettura ed interpretazione delle Carte Geologiche e Tematiche ed alle relative applicazioni di base, tra cui la realizzazione di sezioni geologiche. Il Modulo Carte e Sezioni Geologiche (6 cfu) si integra, non solo ai fini dell'esame, con il Modulo Laboratori di Terreno (8 cfu, distribuiti nei tre anni del Corso di Laurea in Scienze Geologiche).

GEOLOGICAL MAPPING AND FIELDWORK PRACTICALS

The Laboratory activity includes 4 field-work stages, during the three years of the Undergraduate Course in Geological Sciences. The activities are planned as follows.

1) First Year activities:
a - Introductory field trip (1 cfu), aiming to introduce the Students to geological field-work (basic geomorphological, lithological and geological observations)
b - Geological Mapping stage (2 cfu). The Geological Mapping Stage is a 5 days field-work session that is held during summer, after the end of the first year lectures of the undergraduate Course in Geological Sciences. The goals are: i) introduction to observation, description, and interpretation of geological and geomorphological surface features directly in the field, ii) introduction to methods for data collection and management, and iii) first approach to geological mapping. Study Sites and Teachers can vary from year to year. The stage organisation is illustrated to the participants before the end of the first year lectures.

2) Second Year activities:
Geological Mapping stage (2 cfu). This stage is programmed as a field mapping training course over 5 full days, followed by a lab class of one day, devoted to data treatment and to map completion. We illustrate multidisciplinary approaches to the characterization of both rocky substrate and shallow deposits. Macroscopic analysis of sedimentary, igneous and metamorphic rocks is integrated in the regional frame of south Adamello intrusion in the sedimentary sequence of Southern Alps.

3) Third Year activities:
Geological Mapping stage (3 cfu). This stage concludes the compulsory cycle of practical training on geological field-work, aiming to promote the achievement of autonomy in geological mapping, data elaboration (geological map and sections, geological evolution) and applications. The stage will be led by different Teachers, presumably during the months of June or July, in different regions of the Alps and/or the Apennines, that share very high geological and didactical values.

GEOLOGICAL MAPPING AND FIELDWORK PRACTICALS
Classes

1) Introductory notes on contents, scale and types of geological maps
2) Using the geological map and other specific maps;
3) Geological maps as deduced from outcrops and fair copy maps
4) Law aspects and technical report writing
5) Key to map tools: legend (meaning, how it is constructed, etc.), various schemes (stratigraphy, structure, etc), geological cross-sections
6) Computerized maps and GIS (Geographic Information System)
7) Mapping Methodology:
· Sedimentary terranes
· Metamorphic and igneous terrranes
· Volcanic rocks
· Alluvial plains and coasts
Practical exercise:

1) Using the tools of Geological maps/specific maps (e.g., legend, schemes, morphology, symbols)
2) Understanding the geometry (attitude, true dip and apparent dip, thickness, shape) of geologic objects
3) Overlapping and juxtaposition relationships, heteropy
4) Understanding cross-cutting relations: unconformities, dykes, faults, folds
5) Understanding the tectonic structures and structural styles (fold and fault systems, their associations, local vs. regional structural elements, their continuity and geometry)
6) Chronological relations between geologic objects and their geologic evolution
7) Geologic cross-sections:
· Introduction, simple structures
· Continuity, discontinuity, intersection, overlapping relations
· Geologic cross-section in regions with simple folding pattern
· Geologic cross-section in folded and faulted geological settings
· Geologic cross-sections in regions affected by polyphase deformation
8) Writing of the technical report on the geological map and cross-section.
