“…Os isotope data from pelagic successions of Japan show a sharp 187 Os/ 188 Os increase in the Julian (Fig. 4 ), that is interpreted as unradiogenic Os input from Wrangellia emplacement 16 .
Figure 4 A comparison of our Western Tethys composite Hg/TOC stratigraphy with Os-isotopes through the same period associated with the Carnian Pluvial Episode recorded in Japan.

“…A huge amount of Hg was plausibly released by the Carnian Wrangellia oceanic plateau at the time of the CPE. Given the temporal overlap between Wrangellia LIP and the CPE, substantiated by biostratigraphic, radioisotopic, and geochemical data 9 , 16 , 25 , 46 , and in the absence of clear evidence for other dominant Hg drawdown and transport mechanisms, it is plausible to assume a volcanic origin of the additional Hg during the CPE. Wrangellia erupted a minimum of 1 × 10 6 km 3 of basalts onto the Panthalassa ocean floor (Fig.…”
