“…This mineral is enriched in rare earth elements (REE), and is an ideal candidate for U-Pb dating because of its high content of U and negligible content of common Pb. Currently, in situ dating of xenotime is commonly conducted by ion microprobe [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], which can yield precise and accurate ages. However, the expense of this instrumentation hinders the wide application of this technique.…”

“…2), os depósitos auríferos também estão associados a veios de quartzo e brechas que se hospedam nas lavas andesíticas e dacíticas da Unidade Maria Preta, bem como em seus equivalentes subvulcânicos. As paragêneses hidrotermais são carbonato, clorita, ankerita, pirita e arsenopirita (Rocha Neto & Pedreira 1994, Silva et al 2001, Mello et al 2006, Yamana Gold Inc., 2007.…”
