Crushed rock is used as aggregate in concrete, as road sub-base and in flush seals, as facing stone in building construction, and as armour stone and rip-rap. Some dolerite dykes from both massifs show weak negative Eu anomalies, implying the fractionation of plagioclase. The incorporation of 75% dolerite aggregate during pre- and post-heating yielded higher mechanical qualities, based on the findings of an experiment. dolerite bodies; sample (4) is from a lithic breccia zone at the lithologic contact between dolerite and the target granitoids. The contact between dolerite dykes and the host rock, within the weathered zone, remains therefore the most important target for groundwater exploration [ 1 ]. FLAKE is a truly customizable decorative solution for use in a variety of coating systems. These dykes have been emplaced in the older basement composed of granulite. 7Ma (Ekwueme 1994a).
