These domains correlate with the internal compositional structure of the crust as revealed by a three-dimensional density model. Pb-Nd isotopic boundaries thus correspond to variations in crustal compositional structure and reflect Proterozoic mafic-dominated and Paleozoic felsic-dominated crustal lithologies. Age and composition (mafic versus felsic) of these domains have controlled the rheology of the Andean crust, have influenced crustal deformation patterns, and correlate with the central Andean plateau segmentation.", doi = "10.1029/2007GC001925", issn = "1525-2027", journal = "Geochemistry, Geophysics, Geosystems", keywords = "central Andes, mafic, felsic, crustal domains, density structure, isotopic composition", number = "3", pages = "n/a--n/a", title = "{C}omposition and structural control of crustal domains in the central {A}ndes", url = "http://dx.doi.org/10.1029/2007GC001925", volume = "9", year = "2008", }
