Module aim (aims)

The aim of course is to introduce in an easy and comprehensible way the methods and goals of modern geological fieldwork. The field activity of a geologist and genenerally geoscientist is shown as an example of modern fieldwork in natural sciences. The course presents different scopes of fieldwork from the most important one, which is the basic geological mapping through deposit prospecting and exploitation to environmental protection and geotourism. This objective refers to different topographic areas (from mountainous and highland regions built of lithified crystalline and/or sedimentary rocks to lowlands covered by young, soft deposits). In a friendly way, the course combines basic theoretical knowledge with practical exercises, both in-class and open-air ones. Its main part is a field practicum (field trip to the mountains), aimed to give a student the possibility of trying to practice geoscientific fieldwork. As the course is established on the basic level, it is addressed not only to the students of geology (international and Polish ones), but also to the students of other natural sciences (geography, environmental sciences, biological sciences) as well as other disciplines (archaeology, tourism, biology, etc.). The additional purpose of Field Geology course is to develop scientific English vocabulary of the participants, with a special concern to its practical use, trained during the group tasks. The major component of the course is a 4-day field trip to the Polish mountains (Sudetes) with intruguing geological history and fascinating rocks and minerals. This field trip will be an great opportiunity to visit numerous attractive Polish geological exposures (with practical work there). The students will have a chance to observe the landscape in relation to geology of the area, to visit places connected with mineral and rock resources exploitation, today and in the distant past (even several hundred years ago), to visit the geotouristic attractions (some of the most beautiful geosites in Poland). Generally, to meet with beautiful Polish nature.

Pre-requisites in terms of knowledge, skills and social competences (where relevant)

Basic knowledge in the Earth sciences (at the secondary school level).

Syllabus

7 weeks of classroom meetings (15 hrs) plus 4-day field trip (30 hours)
Week 1 Introduction to field geology; objectives of fieldwork in geology, role of fieldwork in modern basic and applied geology, elements of geologist’s field equipment, rules of save and efficient fieldwork.
Week 2 Basics of geological mapping in the field, part 1 - modern methods: preparatory materials (aerial and satellite images, topographic maps, archive materials), application of GIS and airborne techniques in field geology, techniques of mapping in mountainous and Quaternary cover areas, vegetation as an indicator in geological fieldwork. Strategies of geological mapping.
Week 3 Basics of geological mapping in the field, part 2 – map construction techniques: orientation data in geology (orientation notations and symbols), geological compass. Exercises on presentation of orientation data (recalculation of numerical notations, graphic presentation of orientations).
Week 4 Geological structures at the maps and in the field: geometrical fundamentals of geological maps and cross-sections (structure contours, intersection line, intersection module). Organization of geological fieldwork documentation. Rules of geological notebook, techniques of outcrop description and rock sampling.Graphical exercises on presentation and interpretation of uniformingly-dipping strata at geological maps (horizontal, inclined and vertical bedding).
Week 5 Igneous rocks in the field: description of igneous rocks (composition, classification, structures, textures); volcanic, pyroclastic and plutonic rocks and bodies in the field. Types of igneous features. Laboratory (1 h): Drawing of geological cross-section.
Week 6 Sedimentary rocks in the field: description of sedimentary rocks (composition, classification, structures, textures); identification and description of mesoscopic features in organogenic, chemical and clastic deposits, loose and lithified sediments. Paleontological record – field observations, sampling strategies, role in stratigraphy. Week 7 Metamorphic rocks in the field: mesoscopic description (composition, classification, structures, textures); deformation structures in metamorphic rocks (foliations, lineations etc.). Tectonic features in the field, identification and measurements of small-scale tectonic structures (folds, faults, joints etc.), interpretation of large, map-scale tectonic structures (folds, faults, shear zones etc.). Summary of the classroom part of the course.
4-day field trip Field exercises: field excursion to the Sudety Mountains (SW Poland) - preferentially to the Karkonosze Mountain Range.
Objectives: visits in the natural outcrops and artifical exposures; routes in the mountains (Karkonosze National Park and in the Izera Mountains), field description of rocks (with a special concern to magmatic and metamorphic rocks), observation of landforms shaped by past ad current geological processes, recognition and intepretation of basic geologic structures, outcrop profiling, sampling in rock exposures, practical measurements of orientation of geological structures with a geological compass, synthesizing knowledge from field observations, use of the topographic maps and GPS data, learning geotouristic aspects of the visited exposures.
