SiO2 and Rb-Sr ratios vs crustal thickness in central and south western America (NERC grant NE/K008862/1)
A GEOROC (http://georoc.mpch-mainz.gwdg.de/georoc/) compilation of 8,531 analyses of SiO2, Rb and Sr concentrations, in crustal rocks sampled in central and southwestern America, at sites of various crustal thickness. These data were used in Dhuime et al. (2015, Nature Geoscience 8, 552-555) to establish a positive correlation between Rb/Sr (or SiO2) and crustal thickness in sites of generation of new continental crust.

The crustal thickness is calculated from the latitude and longitude coordinates of the samples and the Crust 1.0 model (http://igppweb.ucsd.edu/~gabi/crust1.html), as summarised in Dhuime et al. 2015 (Nature Geoscience 8, 552-555).
