The Quaternary is the youngest period of the Earth's history. Students will get acquainted with the definition of the Quaternary and its position in chronostratigraphic scale. The Quaternary is typical by complicated stratigraphy based on chronostratigraphic, lithostratigraphic, biostratigraphic, chemostratigraphic and magnetostratigraphic principles and archaeological evidences. This results in development of many regional time scales with complicated mutual correlation. Detail Quaternary stratigraphy is associated with need for precise dating methods. An overview of these methods will be one of the contents of the course. Repeated climatic perturbations are characteristic feature of the Quaternary. Their correct interpretation is essential for understanding of current climate change and future climate evolution. The course will present the main theories that explain the causes of climate changes during the Quaternary, including the historical evolution of these theories. The theories are based on long-term records, reconstructed by geological, glaciological, biological and historical proxy data. Repeated climate overturns result in changes in the intensity of weathering processes, erosion and sedimentation, which contribute to the formation of present landscape. They are also related to the migration of animals and plants. Sediments reflecting glacial and periglacial environment are preserved in the Czech Republic. We can observe sedimentary rocks formed by glacial, aeolian, gravitational, fluvial and chemogenic processes.
The student should be able to: - explain the importance and position of the Quaternary in the geological evolution of the Earth. - define the principles of its chronostratigraphic, biostratigraphic and magnetostratigraphic classification. - explain the causes of global worldwide climate cooling and its consequences. - describe the Quaternary glacial and interglacial cycle and its impact on erosional, denudational, and weathering processes. - describe the geological evolution and processes on the territory of the Czech Republic in Quaternary (pedogenesis, aeolic activity, fluvial activity, action of frost and glaciers, periglacial processes, cave sediments, travertines, young tectonic movements). - define the relationship of man and nature in the Quaternary.
