Dimension Stone Exploration and Development in Boki Area Southeastern Nigeria.
Rock specimens can be cut to size and used as slabs, blocks and
columns, where the strong and durable stone has been correctly selected
it has stand the test of time, crushed into aggregates or treated by
cutting and polishing to make them suitable for display or for use in
jewelling. Attractive small irregular shaped specimens can be given a
high polish by hand or by thumbing them in a tumbling machine. Very
hard specimens can need a great deal of work to give them a perfect
polish. Flat surfaces can be given a high polish by hand using
sandpaper. Polishing faceted stones can be quite difficult. All the
cutting of all the faces should be completed before any of them is
polished. In Boki, large deposits of quarry rocks exist which can be
crushed, cut, polished, screened to various sizes and marketed for
different uses such as tiles, roads, bridges, buildings, foundations
and piles construction. This report outlines the availability of
granite and charnockite igneous rocks and granite gneiss metamorphic
rock in Boki area, processes involved in dimension stone production and
investment opportunities in Boki area
