The crystalline rocks in the igneous suite of some part of southern Benue trough, mainly the Anambra basin and the Afikpo basin were studied. The petrographic results show that the rocks are mostly intrusive rocks with few extrusive rocks. The mineral components of the extrusive rocks (basalt and pyroclastics) and some of the intrusive rocks (dolerite, gabbro) are femic, comprising pyroxene, olivine, amphibole, plagioclase feldspar and biotite. The intermediate intrusive rocks (syenite and diorite) are felsic comprising quartz, potassium feldspar and muscovite. These rocks are embodiments of elements (major and trace elements). Quarrying of these rocks into different aggregates create entrance of the elements especially the trace elements into the human system. Some of these trace elements are needed for human sustainability but when the tolerable limit is exceeded, the element becomes hazardous to human health. Most of the trace elements are causative factors to some terminal diseases such as cardiac problem, lungs cancer, skin cancer, kidney damage, stomach irritation, nervousness, weakness, high blood pressure, respiratory organs infection, suffocation, dizziness, unconsciousness, loss of concentration and confusion, tremor, rapid breathing, coma and death. Knowledge of the effects of some of these trace elements are crucial in order to avoid some terminal diseases associated with them.
