REE Accessory Minerals as Regional Metamorphic Processes
Accessory minerals are commonly used in reconstructions of metamorphic evolutions and geotectonic interpretations – from thin section scale to large regions. Significant role in that play REE- and REE-bearing minerals, such as monazite, xenotime, allanite and apatite. These minerals were previously...

| Summary: | Accessory minerals are commonly used in reconstructions of metamorphic evolutions and geotectonic interpretations – from thin section scale to large regions. Significant role in that play REE- and REE-bearing minerals, such as monazite, xenotime, allanite and apatite. These minerals were previously used as in-dicators of metamorphic processes and their P-T conditions by numerous authors (e.g. Finger et al. 1998, Spear and Pyle 2003, Wing et al. 2003). In this paper we present use of interpretations based on reactions involving monazite, xenotime, apatite and allanite compiled with geochronological data in reconstructions of metamorphic evolution of the Isbjørnhamna Group rocks (see also Majka and Budzyń 2006). Polimetamorphic tectonic block, composed of the metasedi-mentary Isbjørnhamna Group, conformably covered by metavol-canosedimentary Eimfjellet Group, is distinguished in SW part |
