Uranium is a widespread commodity throughout the crystalline Bohemian Massif and the basins of its platform cover in the Czech Republic. Most uranium mined occurred in vein- and sandstone-type deposits that cluster in a number of districts within eight uranium regions. Small deposits and occurrences also occur isolated elsewhere in the country. $Figure 3.1 shows the uranium regions with districts and deposits and $Table 3.1 lists reported data of districts and deposits. Since uranium mining was resumed after World War II,74 deposits were mined in 6 districts and at several localities scattered throughout the country.

Uranium deposits and major occurrences have been reported in nine regions and some isolated locations (>Fig. 6.1). Deposits with resource estimates and mining potential are known from six regions: Kokshetau (Kokchetav), N Kazakhstan, Pricaspian, SW Kazakhstan, Chu-Sarysu Basin, south-central Kazakhstan, Syr-Darya Basin, S Kazakhstan, Pribalkhash or KendyktasChuily-Betpak Dala region, SE Kazakhstan, and Ily Basin, SE Kazakhstan. Deposits of limited economic interest are known from the Turga-Priyrtish region, N Kazakhstan, and the Granitnoye and Zhalanshiksky regions in central Kazakhstan.Principal types of uranium deposits include sandstone, veinstockwork, volcanic stockwork, lignite/coal and a special variety of organic phosphorite-type, viz. clay-hosted phosphatized fossil fi sh bone.

Uranium deposits are known from fi ve uranium provinces and some separate areas (>Fig. 1.1, and discussed below) but no complete uranium inventory of China is published since uranium resources are a state secret. Available information on resources is scanty, incomplete, and burdened with discrepancies. It is unclear whether reported fi gures document original resources or the resource status at a specifi c mining stage. Th erefore, data on resources should to be treated with caution. Taking this into account, available information suggests the following general picture of China’s present resource situation (status 2002).

An important prerequisite to the long-term use of nuclear energy is information on uranium ore deposits from which uranium can be economically exploited. Hence the basic purpose of this book is to present an overview of uranium geology and data characteristic for uranium districts and deposits in the United States of America and Latin American countries. With respect to the classification terminology of uranium deposits used in this volume, the reader is referred to the typological classification system of uranium deposits presented in Part I Typology of Uranium Deposits in the first volume of the series Uranium Deposits of the World - Asia (Dahlkamp 2009).
