## Summary

Attached is the single-grain apatite and zircon data obtained for the Karatau-
Talas Terrane, Kazakhstan-Kyrgyzstan. In addition to modelling parameters used
and raw outputs for transparency.  
  
Figure S1. Radial plots for apatite fission-track calculating central ages.
  
Figure S2. Observed vs Predicted mean track length Distribution and Observed
Ages vs Predicted Ages for thermal modelling using QTQt 5.7.0.

Figure S3. Tera-Wasserburg (T-W) concordia diagrams of apatite U-Pb data from
samples A16-34, B15204, and 06-TN-12. Ellipses are plotted at 2 sigma
uncertainties. The dashed lines correspond to linear regressions through the
apatite U-Pb data that were used to obtain an estimate of the initial
207Pb/206Pb ratio (upper intersect of the concordia curve) and the apatite
U-Pb (AUPb) date (lower intercept with the concordia curve).

Table S1. Apatite fission track age and chemical data: ρs is the density of
spontaneous tracks within the region of interest and is expressed as 10^5
tracks/cm2. Ns is the total number of counted spontaneous tracks per sample.
238U is the concentration in ppm of uranium 238 measured in each grain. 35Cl
is the concentration in ppm of chlorine 35 measured in each grain. BLOD is
below limits of detection, and thus could not provide a concentration value
and was not used in calculating sample concentration averages. Dpar is the
average length of spontaneous track etch pits in μm. t is the age of the grain
age in Ma.

Table S2. Zircon fission track age and chemical data: Ns and Ni is the number
of spontaneous and induced fission-tracks respectively. Area is the region of
interest counted. RhoS is the density of spontaneous tracks, RhoD is the
density of dosimeter tracks, RhoI is the density of induced tracks.  
Table S3. Thermal history model input table for simulations of the Karatau-
Talas, Kazakhstan and Kyrgyzstan, based on framework established by Flowers et
al. (2015).

Table S4. 238U/206Pb and 207Pb/206Pb ratios and their associated standard
deviation, as well at their individual error corrections.
