Learning outcomes

Competencies: Knowledge: Deepening and practical application of what have been learned in BSc Sedimentology Knows that models based on data/ observations are used as approximations to describe sedimentation processes Knows and appliess the main principles and concepts of sedimentology and sequence stratigraphy, facies models of the most important depositional environments, factors that form sequences. Distinguishes facies, facies associaton, depositional processes and environments Recognises the elementary building blocks of sequences, their stacking patterns in scale of outcrops, boreholes and basins Distinguishes litho- and chronostratigraphic correlation, applies to interpretation of stratigraphic sequences Knows the possible directions and limitations of sedimentology and sequence stratigraphy Knows the terminology of sedimentology and sequence stratigraphy in both native language and English Ability: Able to recognize geological and applied geological problems that can be solved by sedimentology and sequence stratigraphy Recognizes facies (lithology, sedimentary structures), interprets them from the perspective of depositional processes, documents observations in text and graphics Able to interpret simple sedimentary successions based on knowledge of facies models Able to typify facies and facies assemblages, to describe, document and interpret sedimentary successions independently in terms of processes to changes in the depositional architecture of the environments Recognizes and interprets parasequences, system tracts or sequences in basic well-log and seismic sections Able to carry out chronostratigraphic correlation using geological and geophysical data Based on his/her knowledge, is able to present and discuss his/her results in sedimentology and sequence stratigraphy in a concise and understandable way to other disciplines in Hungarian and English Attitude: Seeks to understand the relationship between nature and man Open to collaboration with other professionals e.g. applied geology, geophysics Committed to quality work, completing assignments accurately and on time Have the creativity, problem-solving skills and flexibility to complete complex tasks Committed to acquire new competencies, expanding knowledge and expertise… Autonomy and responsibility: Has a high degree of autonomy and takes the responsibility for his/her work and professional opinions … Independently recognises basic sedimentological and correlation problems and is able to answer them on the basis of provided information and data Evaluates the results of his/her own work realistically and responsibly. Is prepared to solve independently problems related to sedimentology in the fields of exploration of georesources, environmental and hydrogeology

Course content

Documentation of sedimentary successions: Panoramic view, Sedimentary logs Facies of clastic rocks: Bedforms vs transport and depositional processes (ripples, dunes, mud drapes, mud-clasts Recognition of primary sedimentary structures (planar-, cross-lamination, cross-bedding, hummocky cross bedding, imbrication, Products of mass transport (gradation; fabric); soft-sediment deformation structures, sole marks Reconstruction of depositional environments – facies models: Meandering, braided and anastomosing fluvial systems. Transport directions, water depth, channel depth, width, channel belts, connectedness of sand bodies, alluvial architecture Deep-water slopes, canyons and turbidite systems Wave-dominated shoreface to offshore, tidal signatures, associated ichnofacies, deltaic systems Sequence Stratigraphy: Parasequences and their significance Reconstruction of Parasequences on well logs Parasequence sets, Litho- vs. Chronostratigraphic correlation Depositional Sequences in well-logs: incised valleys, comparison of forced and normal regression, transgression Depositional Sequences in seismic Sequence stratigraphy in the Pannonian Basin

Assessment method

Term mark (five-grade scale) Three tests (20-20%), regular hand-ins and core report (40%)
