Alkaline basalts of Bafang and its environs are consisted of feldspars, olivines, pyroxenes and oxides which appear as phenocrysts, microphenocrysts and microcrysts. Feldspars are plagioclases (An 67.97-15.84 Ab 69.19-30.43 Or 20.59-1.51 ) and anorthoclases (Ab 68.11-61.20 Or 33.87-20.91 An 10.98-4.93 ). Plagioclases are the most abundant amount these feldspars. Anorthoclases appear only in mugearite (BAF 3 and BAF 37) the most differentiated of the studied alkaline-basalts. In High Magnesian basalt, (HMg-B) plagioclases are labradorites (An 67.97-59.30 Ab 38.74-30.43 Or 2.75-1.60 ) and sanidine (An 45.44-31.82 Ab 62.66-51.79 Or 5.52-2.77 ), whereas in Low Magnesian basalt (LMg-B) there are labrador (
