FIG. 9. Representative backscattered electron images of sample UWA-B34, showing analyzed monazite grains (white) in apparent textural equilibrium with chalcopyrite (cpy) and magnetite (mgt) in the matrix of ore-bearing breccias of the Igarapé Bahia Fe oxide Cu-Au-(U-REE) deposit. Other associated minerals are siderite (sid), apatite (ap), and chlorite (chl). The locations of SHRIMP analyses for dated grains are shown as circles. All ages are ²⁰⁷Pb/²⁰⁶Pb ages. Discordant data are marked with a (d). A. B34.5.3-1. B. B34.5.2-1. C. B34.4.2-1. D. B34.7.3-1. E. B34.4.1-1. F. B34.6.2-1.
