Course objectives

The course gives the complex overview of the mineralogical composition of the basic igneous, metamorphic and sedimentary rocks so that the students should be able to work independently with the thin sections within the bachelors works and master theses. Students will learn to find basic types of rocks according to macro-surveys and to specify their names based on microscopic observations, to determine rock structures and textures. They will improve in performing basic petrographic descriptions of igneous, metamorphic and sedimentary rocks.

Syllabus

• The education is focused above all on mastering the practical tasks of optical mineralogy. 1) Work with polarising microscope: Microscopic study of minerals in polarised light: determination of the nicol position, determination of extinction angle, interference colours and birefringence height, function of compensating plates and quartz wedge, their usage, the character of the zone, conoscopy and optical character of minerals: - uniaxial -biaxial 2) The course of determination of minerals in thin sections using polarising microscope: The system of rock-forming minerals:*quartz, potash feldspars, plagioclases (basicity of plagioclase determined with planar table of the polarising microscope), nefeline, leucite, sodalite, nosean, hauyn, analcime, olivine, pyroxenes, amphiboles, muscovite, biotite, phlogopite, cinnvaldite, carbonates, barite, tourmaline, garnets - presumed knowledge from Mineralogy 3) **allanite, zoisite, epidote, klinozoisite, mellilite, chloritoid, chlorite, glaukonite, minerals of the serpentine group, talc, andalusite, sillimanite, kyanite, cordierite, vesuviane, wollastonite, gypsum, anhydrite, fluorite, halite, zeolites , ***skapolite, chondrodite group, prehnite, kankrinite, mullite, periklas, spinels, staurolite, dumortierite, lawsonite, pumpellyite, brucite, corundum, rutile, apatite, zircon, titanite, beryl, topaz, monazite The aim of the microscopic study of rocks are micropetrographic analysis and their confrontation with macroscopic nature of the rocks. The course is focused on the recognition of the following phenomena: Macropetrographic analysis: colour, homogeneity, inhomogeneity, solidity, friability, coherence, incoherence, textural features Micropetrographic analysis: of crystalline phases (minerals) and glass, crystallisation and crystalloblastesis qualitative and quantitative mineral composition (rock classification based on them), grain-size analysis, porosity, mineral and rock alterations, pseudomorphs, form and corrosion of minerals, succession of mineral crystallisation, tokens of rocks contamination and assimilation, structural features, homogeneity and heterogeneity, isotropy and anisotropy of rock texture, crystallisation - deformation, plastic and rupture deformation, healing, cementation, regeneration Petrographic System: 4-6) Igneous rocks: geological position, rock-forming minerals, structures, alterations Classification: - of igneous rocks: alkaline granites, granodiorites, tonalites, diorites, gabbros, peridotites, pyroxenovce, horblendites, syenites, monzonites, alkaline syenites, esexites, theralites, teshinites, umkopaghrites, ijolites, carbonatites,
• - of effusive rocks: rhyolites, dacites, trachytes, andesites, bazalts, fonolites, tefrites, basanites, nefelinites, leucititites, olivinic melilitites Plutonic rocks: distributed mafic and felsic: lamprofyres (a dark-coloured, strongly porfyritic) , aplites, pegmatites and mikrogranites - mikrodiorites - mikrogabbroides volcanic glasses, agglomerates, tuffs and tuffites 7-9) Sedimentary rocks geological position, clastic, chemogenic, organogenic, structural features, groundmass, cement, matrix, porosity. Systematic classification of sedimentary rocks: Clastic sediments: psefites, arenites, aleurites, mudstones, limestones, dolostones, silicites ferrolites, manganolites, phosphorites evaporites Classification principles in individual genetic groups of sedimentary rocks 10-12) Metamorphosed rocks geological position, regionally and contact metamorphosed , structures, groundmass and blastesis Systematic classification of metamorphosed rocks: Contact metamorphosed rocks: cherts, plodové shales, snopkové (sheaf?) shales, blotty (skvrnité) shales Regionally metamorphosed igneous rocks: acidic, intermediary, basic, ultrabasic (ortho-gneisses, granulites, metabasites, green shales, amphibolites, leptinites, serpentinites, krupníky, talc shales etc. Regionally metamorphosed sedimentary rocks: phyllite, mica-schist, para-gneiss Contact and regionally metamorphosed rocks: carbonate marbles Graphitic rocks Metaferrolites Further: skarns, eclogites, metasomatites etc.
