AB  - 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.
