Brick clay geology and mineral planning

Rocks and Minerals, Kentucky Geological Survey, University ...

Eastern Kentucky has several brick plants that mine clay for common brick. Many of the clays beneath coal beds (called underclays) have potential for various types of brick, including common clay. One plant near Grayson has been in operation for many years and produces clay from Pennsylvanian rocks.

Clay | geology | Britannica.com

Clay, soil particles the diameters of which are less than 0.005 millimetre; also a rock that is composed essentially of clay particles. Rock in this sense includes soils, ceramic clays, clay shales, mudstones, glacial clays (including great volumes of detrital and transported clays), and deep-sea clays (red clay, blue clay, and blue mud).

Online Rock and Mineral Kit - Ohio Geological Survey: Home

Clay becomes very hard when heated to a high temperature, so it is used to make pottery, bricks, ceramic tile, and other clay products. Ohio is one of the leading states in the production of clay and shale. Because of abundant clay deposits, Ohio has long had a large and important ceramic industry.

Environmental Characteristics of Clays and Clay Mineral ...

Clay minerals have a wide range of particle sizes from 10's of angstroms to millimeters. (An angstrom is a unit of measure at the scale of atoms.) Thus, clays may be composed of mixtures of finer grained clay minerals and clay-sized crystals of other minerals such as quartz, carbonate, and metal oxides.

Kaolin - Earth Resources

The kaolin-forming clays are all hydrous aluminium silicates, essentially kaolinite [Al 2 (Si 2 O 5)(OH) 4], that are formed by the decomposition of other aluminous minerals, especially feldspars. Kaolin deposits can be nearly pure kaolinite or may contain impurities that affect the characteristics of the clay.

Clay is a very fine grained natural rock or soil material made up of one or more clay minerals. As with most things in geology there is no academic consensus on clays – specifically on the groups of clays. Clays are much more complicated than people think – but can be broken down into kaolinite, montmorillonite-smectite, illite +/- chlorite.

The Division of Geology and Mineral Resources collected ten samples of clay, shale, and related materials in Loudoun County during a survey of potential resources in the early 1960s. Shales from selected localities east of Lucketts, near Arcola, and north of Hillsboro were found potentially useful for the manufacture of brick.

The Geology of Bricks - thoughtco.com

The main ingredient of bricks is clay, a group of surface minerals that arise from the weathering of igneous rocks. By itself, clay is not useless—making bricks of plain clay and drying them in the sun makes a sturdy building "stone." Having some sand in the mix helps keep these bricks from cracking.
