(2,650 ±140 m.y.; Sims and others, 1977). The granitoid rocks that have been dated have an initial ^Sr/^Sr ratio of 0.7015 ±0.0017, which is interpreted as indicat­ ing a lower-crust or mantle source. As described in chapter A , a belt of gneiss, amphibo- lite, and granitoid rocks, about 5 to 10 km wide, lies

nant granitoid rocks. Intercalated with the granitoid rocks in small to large conformable bodies are biotite gneiss, amphibolite, and local tonalite gneiss. Metagabbro dikes of probable Early Proterozoic age as much as 15 m thick cut the Archean rocks. Rubidium-strontium whole-rock data indicate a Late Archean age in Granitoid Rocks and Constituent Minerals, Central Sierra Nevada Batholith, California By F. C. W. DODGE, H. T. MILLARD, JR., and H. N. ELSHEIMER GEOLOGICAL SURVEY PROFESSIONAL PAPER 1248 A geochemical study of the lateral compositional variations in granitoid rocks across the central Sierra Nevada batholith Perturbation on the simplex is an operation which can be used to numerically describe changes in the composition of, for example, soils, sediments, or rocks. The combination of perturbation and power transformation provides a strong tool for Granitoid rocks can be subdivided in two main ways: (1) by referring to geographically contiguous bodies (batholiths); and (2) by reference to groups of rocks which have similar chemistry, mineralogy, and usually age (suites). Batholiths On the basis of the definition of batholith given above, the granitoid rocks of Westland-Nelson can A granitoid is a generic term for a diverse collection of coarse-grained igneous rocks that consist predominately of quartz, plagioclase, and alkali feldspar.
