Major Minerals The abundance of antimony in the Earth's crust is estimated to be between 0.2 and 0.5 ppm, comparable to thallium at 0.5 ppm and silver at 0.08 ppm. Although this element is not abundant, it is f
Due to Th's radioactivity, minerals containing it are often metamict (amorphous), their crystal structures having been destroyed by the alpha radiation produced during thorium decay. An extreme example is ekanite, (Ca,Fe,Pb)2(Th,U)Si8O20, which nearly never is found in crystalline form...
