Book Description
Describes the geology, geochemistry and associated mineralization of the Cross Hills Plutonic Suite. The plutonic rocks give imprecise Rb-Sr ages of about 560 Ma, and intrude late Hadrynian metavolcanic and metasedimentary rocks of the Long Harbour Group. Minor occurrences of Zr-Nb-Y-Th-REE occur in aplite veins and fractures in the peralkaline granite.
