Samarskite-(Y) Mineral | 3.4 grams | South Platte Pegmatite Mining District | Jefferson County, Colorado, USA Sodalite because Vesuvianite often appears toSamarskite is a radioactive rare earth mineral. Samarskite crystallizes in the orthorhombic dipyramidal class as black to yellowish brown stubby prisms although it is typically found as anhedral masses. Specimens with a high uranium content are typically metamict and appear coated with a yellow brown earthy rind. Samarskite (Y) is rich in rare earth elements (REEs), niobium (Nb), and tantalum (Ta)all of which are valuable in advanced electronics,
