This study reports precise and accurate data for rare earth elements (REE) measured on eight geological reference materials, five enriched in REE (BE-N, BHVO-2, BR, BR-24 and RGM-1) and three very depleted in REE (BIR-1, UB-N and DTS-2). Data were acquired by quadrupole ICP-MS after isolation of the REE using an ion-exchange chromatography procedure. All the measured REE abundances are similar ...

The studied serpentinites occur as isolated masses, imbricate slices of variable thicknesses and as small blocks or lenses incorporated in the sedimentary matrix of the mélange. They are thrusted over the associated island arc calc-alkaline metavolcanics and replaced by talccarbonates along shear zones. Lack of thermal effect of the serpentinites upon the enveloping country rocks, as well as th...

Glaucophane-bearing rocks — indicators of high-pressure metamorphism were earlier found in the Polar Urals Neoproterozoic deposits Nyarovey series, northern part Marunkeu eclogite-amphibolite-gneiss complex, and foot ultramafic massifs Main Ural Fault (MUF) zone. We have discovered western endocontact Kharbey amphibolite-gneiss where they are represented by garnet-glaucophane, garnet-glaucophan...
