Principles of application of fluid inclusions for the study of hydrothermal mineralizations

The bachelor thesis is subdivided into two review parts and one experimental part. The first part focuses on petrography and microthermometric study of fluid inclusions. Petrography chapter lists genetic types of inclusions, and various mechanisms that determine their shape and digree of fill. Emphasis is placed especially on the microthermometric study of fluid inclusions. The phase changes in H2O - NaCl and H2O - CO2 - salts systems at low and high temperatures are described in detail. A separate chapter is dedicated to interpretation of microthermometric data and to their use in determination of pressure-temperature conditions of minerals formation. The second part of the thesis lists several examples of using the fluid inclusions in the study of hydrothermal deposits and in prospecting of ore deposits (Pb - Zn - fluorite deposits of Mississippi valley type, porphy - type, Cu - ores at Bingham). One chapter is dedicated to Bleïda deposit (Morocco), Kanmantoo deposit (Australia) and San Cristobal vein (Peru). This chapter discribes geology, mineralogy and fluid inclusion data of these deposits. Third, experimental, chapter deals with hydrothermal mineralization in the Ševětín quarry. It includes the regional geology of Ševětín massif, geology of the quarry and the mineralogy of hydrothermal..
