The mica mines of the Kodarma area in the Hazaribagh district of Bihar contribute as a single unit the largest quantity of muscovite (locally known as "Ruby mica") to the world. The mica-pegmatites of this area have attracted the attention of geologists and mining engineers since the beginning of the last century, but still many petrological problems connected with them have not been satisfactorily solved. During recent years the present authors have studied the geology of the Government Reserve Forest of Kodarma; and they intend to discuss in this paper the origin and the characteristic features of the Kodarma pegmatites and to review the literature already existing on this subject.
