Microscopic photograph shows the backing Fossiliferous limestone (Biomicrite) blocks of Mykerinos pyramid. The rock is very fine to fine-grained. Significant amount of microfossils of different sizes and shapes are present in the matrix. Few pore spaces (irregular shapes and sizes) are present in heterogeneous distribution in carbonate matrix of the rock. The rock is composed mainly of calcite as the essential component associated with minor amount of iron oxides and rare amounts of quartz, gypsum and opaque minerals. Calcite represents the majority of the matrix of the rock and occurs as very fine-grained aggregates, anhedral crystals interlocked with each other’s. Iron oxides occur in considerable amount as fine-grained aggregates and also as patches stained some parts of the sample
