TANGO (TransANdean Great Orogeny) is a multi-disciplinary project focused on identifying processes responsible for variations in crustal thickness and uplift along the Andes by exploring the combined roles of the lithosphere, asthenosphere and lower mantle. TANGO is funded by the NSF FRES program.
• How did the crust thicken and why is crustal thickening variable along strike?
• Is crustal thickening responsible for surface uplift?
• Are along-strike differences in shortening responsible for differences in orogen width or are such variations a function of differences in erosion, climate, or inherent continental plate structure (top-down control)?
• Alternately, are deeper lithospheric-mantle scale processes operating to control these attributes (bottom-up control)?
• How are mantle-generated stresses transferred into the continental orogenic lithosphere?
• Why was Andean crustal thickening delayed until the Cenozoic, despite a longer history of convergence between the South American and Nazca plates?
