The
aim of this chapter is to use geochemistry to determine the economic potential
of marble from Ikpeshi area. Nigeria has a variety of rich solid minerals and
rocks such as marble which if fully exploited will boost the economic
potentials of the country. Forty five (45) marble samples were collected and
subjected to petrographic, physical analyses and geochemical analysis using the
inductively coupled plasma –mass spectrometry (ICP-MS). Geochemical data
indicated that the marble deposits at Ikpeshi has variable geochemical
characteristics; some have low dolomite CaMg (CO3)2 (1.35-7.44%) and high
calcite CaCO3 (82.78-95.61%) while the Golden Girl quarry has moderate dolomite
(41.38-41.42%) and moderate calcite (61.03-61.58%). Physical tests indicated
high tensile strength (17.342-31.550MPa), compressive strength
(259.515-3892.73MPa) and shear strength (44.70-68.51MPa), respectively.
Petrographic studies revealed that the marble contains calcite, dolomite,
quartz, opaque mineral, actinolite, lead, feldspar and chlorite at various
proportions. Based on these characteristics, the marble from Ikpeshi is
suitable as raw materials for manufacture of lime, drugs, toothpaste, paper and
paint. It is also important in the production of livestock feed, electrical insulators,
flooring tiles and terrazzo chips. The marble is unsuitable as a raw material
for the production of cement unless blended.
