Marble is a metamorphic rock composed essentially of calcite (CaCO3), dolomite [CaMg (CO3)2], or a combination of the two, with a fine- to coarse-grained crystalline texture (Serra, 2006). Marble is a metamorphosed limestone. Limestone and marble are carbonate rocks, dominated by the mineral calcite (CaCO3).

The high demands for crushed rocks as construction materials in the Cross River State and elsewhere in Nigeria have led to the establishment of many granite quarries by investors for the production of rock aggregates. In southeastern Nigeria, basement rocks are known to occur at Oban and Obudu regions (Ekwueme, 1988, 1990, 2003).
Coarse aggregates from three different natural parent rock materials were obtained viz igneous- crushed granite stone, sedimentary rock -limestone and metamorphic rock -marble stone [28, 29]. The fractions of different sizes of the aggregates as shown in Table 1 were in the ranges as specified in [29].
