... and 1.39 Ga ( Peterman et al. 1968 ; Stern et al. 1971 ). The Longs Peak-St. Vrain batholith was emplaced at shallow depth (0.2–0.3 GPa; Anderson and Thomas 1985 ). The presence of Paleoproterozoic xenoliths (mainly <1.76 Ga biotite schist; Selverstone et al. 2000 ) further indicates that the studied...

... for the Silver Plume, St. Vrain, and other peraluminous granites of DePaolo (1981) range from + 0.2 to −2.3. The data are consistent with derivation from melting of older Protero-zoic crust of differing Sm/Nd ratios. Minor incorporation of an Archean component is possible for the Sherman batholith only in its...
