Quantitative characterization of orogens through isotopic mapping
Abstract The relationship between orogens and crustal growth is a fundamental issue in the Earth sciences. Here we present Nd isotope mapping results of felsic and intermediate igneous rocks from eight representative and well-studied Phanerozoic orogens. The results illustrate the distribution of is...

Abstract The relationship between orogens and crustal growth is a fundamental issue in the Earth sciences.
