Resumen
Among the Spanish Central System plutons, La Pedriza granite pluton (Sierra de Guadarrama) is the one with richest Rb, Ga, Nb, Y, REE,, Th and U contents. As a consequence, this pluton shows a wide variety of accessory minerals rich in those components. We have found scarce (Y,HREE,NbjlNbl-, (Mn,Fe)1 Nb2, UINbl- and (Y,HREE) 1 Ti2-minerals, which probably correspond to yttroco!umbite-(Y), manganocolumbite, uranopyrochlore, aeschynite-(Y), respectively. In addition to these, thorite, uraninite, zircon, monacite-(Ce), xenotime-(Y), allanite-(Ce), rutile and bastnäesite-(Ce) also occur.
