Within a 20x20 km area near Gakara metasediments, gneisses and granites are cut by sets of veins and veinlets, which often form dense stockworks that are concentrated in three zones. The veins consist of quartz, baryte, microcline and biotite with a broad range of rare earth and other minerals, including bastnaesite, monazite, cerianite, fluocerite, pyromorphite, Ce and La rhabdophane, galena and other sulphides. There are potassic metasomatic zones adjacent to the veins. The principal REE mineral in the veins is bastnaesite and analyses of this using several techniques are given and discussed by Lehmann et al. (1994), while further REE data of this and other RE minerals are given by Van Wambeke (1977). This location is included here because Van Wambeke, and some earlier writers, have suggested that this occurrence is related to carbonatite, although carbonates do not occur in the veins. Others have suggested an association with granite. The position is unclear at present.
