Figure 3.

Results of new Sr/Y and La/Yb proxy calibration applied to data from the Tibetan Magmatism Database (Chapman and Kapp, 2017) located in the eastern Gangdese Mountains in southern Tibet. (A) Filtered Sr/Y and La/Yb data extracted from 29 to 31°N and 89 to 92°W. (B) Values from part A converted to crustal thickness using Equations 1, 2, and 3 (see text). (C–D) Temporal trends based on multiple linear regression of Sr/Y–La/Yb–km; trends are calculated from 10,000 bootstrap resamples, with replacement. (C) Gaussian kernel regression model to determine a continuous thickening history. (D) Linear regression to determine linear rates for critical time intervals.
