Rare earth elements (REE)–thorium−bearing minerals form pods and lenses within pegmatites hosted by the Proterozoic Burro Mountain granite in the western part of the White Signal district. Quartz, muscovite, and microcline are the primary minerals of these pegmatites. Large euhedral crystals of euxenite [Y,Ca,Ce,U,Th)(Nb,Ta,Ti)2O6] are found locally, and some crystals are several inches long (Gillerman, 1964). Other REE-bearing minerals reported in the pegmatites are allanite and samarskite (Richter and others, 1986). In the Gold Hill area, near the crest of the Burro Mountains, the same REE-bearing minerals are hosted in similar but larger pegmatites that also cut the Burro Mountain granite (Hedlund, 1978). The primary pegmatite minerals are milky quartz, microcline, albite, and muscovite with accessory biotite, magnetite, garnet, fluorite, and REE-bearing minerals such as allanite, euxenite, and samarskite.
