Age of rare-metal pegmatites from the Vasin-Myl’k deposit (Kola region): Evidence from U-Pb geochronology of microlite

Rare metal pegmatites occur worldwide being Pre cambrian to Paleozoic in age. Most of them represent Archean and Proterozoic rocks. A peculiar feature of rare metal pegmatites is their confinement to Pre cambrian greenstone belts [1]. The main problems related to these rocks to be investigated are t...

Description
Summary:Rare metal pegmatites occur worldwide being Pre cambrian to Paleozoic in age. Most of them represent Archean and Proterozoic rocks. A peculiar feature of rare metal pegmatites is their confinement to Pre cambrian greenstone belts [1]. The main problems related to these rocks to be investigated are their genetic relation, if there is any, with granites and the age of ore mineralization. They may be solved by car rying out isotopicgeochronological investigations aimed at dating the formation of parental granites and immediately pegmatites themselves.
