Geotagging - geological information to your mobile phone (Bohemian Paradise Geopark, Prachov Rocks locality)
Novotná, Jana ; Matějka, Dobroslav (advisor) ; Kühn, Jiří (referee)
In my bachelor work is described the use of geotagging which is information technology for giving geological information and knowledge to tourists or experts. In the text states how geotagging works, how to use tags - or QR codes (Quick Responce) to obtain information about the location or phenomena that are frequented by tourists. Furthermore, there is about technological parametres of tags and their generation. For the practical use was chosen European Geopark Bohemian Paradise. In this Geopark were selected locations in the Prachov rocks that will be soon tagged; these sites are described in geological detail and have a brief historical information. Some tags also contain images and accompanying animations. For completion contains work map of geopark, map with trails and detailed photo documentation. The aim of this work is to provide other important geological sites in the Bohemian Paradise Geopark by tagglists with information about the geology and formation of Rock city. This work is based on project: "Information technology in Bohemian Paradise Geopark.".

Mineralogy in the School curricula
Kálalová, Anna ; Matějka, Dobroslav (advisor) ; Ziegler, Václav (referee)
This bachelor thesis is focused on teaching geology and mainly mineralogy on grammar schools. Questionnaire was made for purposes of this bachelor thesis. Objective of this questionnaire was to ascertain information about organization teaching geology and mineralogy on these types of schools and their inclusion in the school curricula. The questionnaire results showed that each school is very different in organization of teaching geology. Mineralogy is most often taught in first classes of four-year, or an equivalent multi-year study. Mineralogy is at some schools taught only in classes corresponding to an elementary school. Optional subject in which is the geology taught students may choose only to nearly forty percent of surveyed schools. Schools use a lot of sorts of material - textbooks for elementary and secondary schools, university textbooks, professional books and Internet resources. The most common tools used in the teaching of geology are collections of samples. Very frequent are also models of crystals and the geological maps. Fewer common are paintings, photographs and films with a geological theme. Uncommon are tools for microscopy and geological compass. 48 % of grammar schools incorporate to education laboratory work and geological or mineralogical excursion, 4 % only laboratory...

Raw materials of Manětín area and their presentation in the form of educational patthway
Čada, Martin ; Přikryl, Richard (advisor) ; Matějka, Dobroslav (referee)
This bachelor thesis focuses on the geological history (Late Proterozoic to Quaternary) of the Manětín Permian-Carboniferous basin. It also studies the historical and present use of raw materials (ores, non-metallics, caustobiolites) in the Manětín area, the northern part of the Plzeň-sever district. In appendix, information panels of the educational pathway are proposed. The Manětín basin consists of two structural levels. The lower one (Proterozoic metapelites) forms the base of the basin. The upper one (Permian-Carboniferous clastic sedimentary rocks) is the filling of the basin. There are also a few Proterozoic and Tertiary volcanic bodies. In the past, ore deposits (gold, silver, iron) had been exploited in the Manětín area. Non-metallics (glass sand, ocher, pyrite-slate, roof-slate, structural clay products, arkose) had been largely used, too. There was only a small scale extraction of caustobiolites (humites). Today's extraction is focused on natural stone (crushed stone) only (Zahrádka and Březín deposits). The proposal of the educational pathway contains seven information boards, that show the geological history of the Manětín basin and the use of local mineral raw materials (gold, slate, natural stone) with it's influence on the landscape, society and industry, particularly glass production. The...

Phosphates and accessory oxides in selected granitoids and paragneisses of the Moldanubian area in southeastern and southern Bohemia
Procházka, Václav ; Matějka, Dobroslav (advisor) ; Štemprok, Miroslav (referee) ; Petrík, Igor (referee)
The thesis deals with granites and paragneisses prevalently in the area of northern Moldanubian Batholith (especially the Melechov massif). The main object are accessory minerals, also some information replenishing the knowledge about geochemistry and petrography of studied rocks has been obtained. The research has been focused mainly on phosphates and Fe-Ti oxides. Fluorapatite (only "apatite" in the following text) is common in all granitoids as well as paragneisses. In metamorphic rocks and in little fractionated granites (the Lipnice and Pavlov types), apatite is very homogeneous and only exceptionally corroded. In more fractionated granites, complicated evolution of apatite has been documented with the usage of cathodoluminescence. The cathodoluminescence is influenced mainly with admixtures of Fe, Mn, Y and REE, as documented in literature. In addition, irradiation (mainly from monazite inclusions) darkens the luminescence, and the influence of uneven surface is also significant. The contents of Na, Fe, Mn, Y and REE are higher in the interior of unaltered crystals. Trace-elemnt determination (LA-ICP-MS) in apatite in granites of Melechov massif also shows that the unaltered primary apatite has also higher U and lower Sr content, deeper negative Eu-anomaly, and more pronounced M-type tetrad...

Low-temperature evolution of granulites in the Moldanubian Zone of the southern Bohemian Massif
Kořínková, Dagmar ; Svojtka, Martin (advisor) ; Matějka, Dobroslav (referee)
The Variscan orogeny occured during Devonian to Carboniferous convergence between peri- Gondwanan crustal segments and the northern European plate (Baltica). Due to the convergence, Bohemian Massif represents the easternmost and largest exposure in the European Variscan belt. In the southern part of the Bohemian Massif, the Moldanubian Zone consists of several crustal segments with different polyphase tectonometamorphic histories. Moldanubian Zone is considered to represent the Variscan orogenic root, being surrounded by rigid and less metamorphosed blocks to the NW and SE. Structurally highest unit of the Moldanubian Zone is the Gföhl Unit, which is built by heterogeneous assemblage of high-pressure crustal and upper-mantle rocks comprising granulites, peridotites, pyroxenites and eclogites exhumed during Variscan orogeny. The apatite samples studied in my diploma thesis come from different types of granulites from the Blanský les granulite massif (BLGM) located SW of the town of České Budějovice. BLGM is the largest granulite body of the southern Bohemian Massif, is an integral part of the Gföhl Unit. BLGM consists mainly of calc-alkaline high-pressure felsic garnet ± kyanite granulites, which enclose up to several kilometers long lenses of ultrabasic rocks, numerous boudins of mafic...

Education trail along "Blažejovický potok" brook
Neubauerová, Kristýna ; Holcová, Katarína (advisor) ; Matějka, Dobroslav (referee)
This thesis deals with the characteristic of the Vysočina region and with a project of founding an educational natural trail "Povodím Blažejovického potoka". The thesis consists two parts. The first theoretic part describes the Vysočina region in light of geomorphological, biological, geological, natur protection and in which chapter is emphasization the area, in which is situated the lane of educational trail. It is compilatory text, which is composion like guide book to the Vysočina region for teachers, who decide for visit with their students not only this education trail, but another places in the Vysočina region too. They can find in the text another interesting places to visit. On the end of theoretic part are two chapters, historical interests and explication the concept of the education trail. The second, practical part include individual information boards with thematic content and their graphic layout. The education trail has 7 km with 12 information boards. It is the combination education trail, it has 1 introductory board, 3 boards with historical informations, 1 geological board, 2 botanical board, 1 zoological board, 2 ecological boards and 1 board about technical memory.
