Abstract
The Sara-Fier granite suite is one of the several anorogenic younger granite complexes that is located approximately 120 km South East of Jos, Nigeria. The complex is found to comprise of felsic rocks like; biotitegranites, biotite microgranites, hornblende biotite granites, pyroxene fayalite granites and syenite. They are also found to be associated with mafic rocks like gabbroic diorites and diorites which at some portions have formed hybrid rocks. The complex intruded the basement rocks of central Nigeria. Structural trends on these rocks suggest that they were controlled by some deep seated structures of the basement. Mineral suite identified include; fayalite, pyroxene, amphibole, k-feldspar, biotite, quartz, iron-oxide and accessory minerals like zircon, apatite and allanite. Generally, the petrography of these rock samples reveal the presence of a mafic magma which has two pulses (a mafic and felsic pulse) of injection.
