01/03/1994 · Standard petrographic methods were used to study 604 modern sands from South America, of which 351 came from rivers and 253 from beaches. In spite of the wide geomorphic contrasts, these sands belong to only three great families: (1) an immature Andean family of lithic arenites rich in volcanic and metamorphic grains that covers about 30% of South America; (2) a cratonic .

Sands from rivers and sea cliffs were also analyzed as potential sources. Four principal beachsand sources are identified by factor analysis: the Columbia River on the north, a Coast Range volcanic source, sands from the Umpqua River on the south Oregon coast, and a metamorphic source from the Klamath Mountains of southern Oregon and northern California. Most beach sands consist of mixtures ...

We present here a possible solution based on factor analysis of compositions illustrated with a case study. We find two factors on the compositional biplot fitting two noncentered orthogonal axes to the most representative variables. Each one of these axes defines a subcomposition, grouping those variables that lay nearest to it. With each subcomposition a logcontrast is computed and ...
