Characterization of non-equilibrium and equilibrium occurrences of paragonite/muscovite intergrowths in an eclogite from the Sesia–Lanzo Zone (Western Alps, Italy)
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-04)
Coexisting muscovite and paragonite have been observed in an eclogite from the Sesia–Lanzo Zone (Western Alps, Italy). The P - T conditions of this eclogite reached 570–650 °C and 19–21 kbar and the rocks show several ...

Changes in Sr/Ca, Ba/Ca and 87Sr/86Sr ratios between trophic levels in two forest ecosystems in the northeastern U.S.A.
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-04)
The variability and biologicalfractionation of Sr/Ca, Ba/Ca and 87 Sr/ 86 Srratios were studied in a soil–plant–invertebrate–bird food chain in two forested ecosystems withcontrasting calcium availability in the ...
