Resumo
New U‒Pb (SHRIMP II) data on the age (2661.8 ± 7.1 Ma) and isotopic (Sm‒Nd) composition of the Patchemvarek gabbro‒anorthosite massif located in the junction zone between the Neoarchean Kolmozero-Voron’ya greenstone belt and Keivy paragneiss structure are discussed. The established age and geological‒tectonic position of gabbro‒anorthosites allow the prognostic metallogenic estimate of Ti‒V‒Fe mineralization to be extended to the entire Kolmozero-Voron’ya‒Keivy infrastructural zone of the Kola‒Norwegian province of the Fennoscandian shield.
