...Paolo ORLANDI; Marco PASERO; Nicola ROTIROTI; Filippo OLMI; Francesco DEMARTIN; Yves MOËLO Abstract Gramaccioliite-(Y) is a new mineral within the crichtonite group. It was found in the gneiss of the Hercynian Massif of Argentera, at Sambuco (Stura Valley, Piedmont, Italy). It occurs as black...

... ), and gramaccioliite-(Y), (Pb,Sr)(Y,Mn)Fe 2 (Ti,Fe) 18 O 38 , from Stura Valley, Italy ( Orlandi et al. , 2004 ). Interestingly, a new structural sub-unit, consistent with the “ M 20 O 39 ” formula, has been reported for an unusual senaite enriched in U, the A site of which is occupied by O ( Armbruster & Kunz...

...-seated gravitational slope deformation (DSGSD), had a dramatic impact on the morphology of the study area, namely on its slope-plain system,from the top of slopes to valley floors. Distinctive characteristics of these phenomena are creep deformations ( Zischinsky 1969 ; Nemcok 1972 ; Mahr 1977...

Present river sands were sampled from the Maira, Stura, and Tanaro Rivers ( Fig. 1 ). The Maira drains the polymetamorphic HP-UHP units of the southern part...

The geomorphological criterion is based on the identification of morpho-tectonic and drainage elements, such as rectilinear or segmented patterns of valleys, scarps, and ridges, drainage pattern offsets, and stream-segment alignments...
