Fig. 7: Plots of compiled multi-disciplinary evidence.
From: Final closure of the Paleo Asian Ocean basin in the early Triassic
It shows the spatial-temporal evolution of a inherited & detrital zircon εHf(t), b bulk-rock Sr/Y; data distribution of scatter plot is evaluated by Voronoi density134. c εNd(t) and d Nb/Yb of arc intermediate rocks among the MFAB, CTS, ETS region, and NTC; crustal thickness is derived from the method of ref. 135; yellow and red arrows indicate the evolution of mantle “signal” respectively beneath ETS and CTS Arc regions. e KDE plot of ages of regional arc intermediate rocks; ages marked by numbers 1–4 with black star are respectively cited from refs. 68,135,136,137,138. f KDE plot of ages of regional metamorphism, depositing, and main strike-slip faulting & thrusting events; ages marked by numbers 5–10 with black, colored stars are respectively cited from refs. 3,139. The widespread rapid cooling signal85,86,87,88,89 from low-temperature thermochronology across the STOB, in response to the final amalgamation of southern Altaids, is highlighted by cyan column. g Bulk-rock εNd(t)-zircon εHf(t) isotope diagram for ~260–330 Ma arc or plume-related intermediate rocks from regional tectonic untis; the error bars are derived from the variation of zircon εHf(t) values of individual intermediate rock in region. Relevant data are presented in Tables S2–S4. Compiled regional data are listed in Tables S6–S7.
