Ceramic clays from the western part of the Tamnava Tertiary Basin, Serbia: Deposits and clay types

Abstract

Based on geological, mineralogical, physical, chemical and technological investigations in the Tamnava Tertiary Basin near Sabac town (western Serbia), deposits of ceramic clays were studied. These ceramic clays are composed of kaolin-illite with a variable content of quartz, feldspars, mica, iron oxides and hydroxides, and organic matter. Four main types of commercial clays were identified: i) red-yellow sandy-gravely (brick clays); ii) grey-white poor sandy (ceramic clays); iii) dark-carbonaceous (ceramic clays); and iv) lamellar (?interspersed?) fatty, poor sandy (highly aluminous and ferrous clays). Ceramic clays are defined as medium to high plastic with different ranges of sintering temperatures, which makes them suitable for the production of various kinds of materials in the ceramic industry.

The Environmental Impact of Radionuclides From Soil and Clay Material Found in "Zbegovi" Deposit in Donje Crniljevo

“…Basalt In the middle part of the 20 th century, economically interesting quantities of ceramic clay deposits were discovered in the western part of the Tamnava tertiary basin (Western Serbia) [9]. The studied deposits of plastic pottery clays are rather small and mainly located in the wider area of the village of Donje Crniljevo.…”

“…Clays usually appear at a depth of 2-35 m [9]. The Miocene productive series ends with various sands, gravels and conglomerates.…”

“…On the basis of mineral, physical, chemical and technological examination of the quality of composite crude ceramic clays from active deposits in Donje Crniljeve [9], following four types of commercial clay were isolated in the sediments of the Jovanovića Brdo, the Bele Vode and the Zbegovi (opened in 2007): a) red-yellow sandy-gravel clay (brick clay); b) grey-white poor sandy clay (ceramic and refractory clay); c) dark coal clays (ceramic clay); d) interspersed (lamellar), fatty and poor sandy clay (distinguished by the high content of aluminum and iron). Brick clays are intended for internal use, and the most important is the grey-sandy ceramic clay, which was used for the production of white facade brick.…”

“…Brick clays are intended for internal use, and the most important is the grey-sandy ceramic clay, which was used for the production of white facade brick. All three types of ceramic clays from the Tamnava tertiary basin can be widely used in non-metal processing industry; therefore, these deposits could greatly contribute to further economic development of this part of Southeast Europe [9].…”

“…Location and geological map of the Tamnava tertiary basin [9] By analyzing the obtained data on the mineralogical composition of the examined ceramic clay deposits in the Tamnava basin, it can be concluded that they differ in the granulometric composition (different proportions of sand, dust and clay fraction) and they contain other substances (quartz, smectite clay, iron minerals, organic matter).…”
