Course objectives
Volcanic rocks are important in interpretation geological records because of their geochemistry reflect geotectonic settings and petrographical characteristic (textures, structures) are useful for reconstructing paleoenvironment during volcanic eruptions. Five lectures present short summary volcanological terminology and main volcanic processes are demonstrated on the typical examples from the field, also provide summary volcanic structures and types of volcanic eruptions. We will discuss topics such as volcanic and postvolcanic processes, eruptive environments, lava flow and their types, classification and common features of pyroclastic rocks, hydrothermal alteration and erosion of volcanic terrains, volcanic risks and benefits.
Syllabus (in Czech)
  • I. Úvod
  • A. Co je to magma
  • B. Klasifikace produků vulkanické aktivity (Produkty ztuhnutí lávy – výlevné horniny, produkty sopečných explozí - pyroklastické horniny a vulkanoklastické sedimenty)
  • II. Typy erupcí
  • A. Erupce a sopečné tvary
  • B. Rozdělení vulkanických tvarů podle aktivity, délky trvání aktivity, tvaru vulkanického centra, převažujícího produktu exploze, genetické rozdělení
  • C. Rozdělení podle charakteru erupcí (typ havajský, strombolský, vulkánský, peléský (katmajský), pliniovský, trhlinová erupce, hydrovulkanická sopečná činnost, podmořská sopečná činnost, sopečná činnost pod ledem).
  • III. Produkty vulkanické aktivity
  • A. Lávy (kyselé lávové proudy a dómy, bazické a intermediální lávové proudy)
  • B. Produkty sopečných explozí (tefra, ignimbrity, lahary, hyaloklasty, epiklastika)
  • IV. Postvulkanické procesy
  • A. Doprovodné a postvulkanické jevy (výrony plynů, gejzíry, termální prameny, bahenní sopky)
  • B. Hydrotermální alterace
  • C. Eroze a vulkanické tvary
  • V. Důsledky vulkanické aktivity
