Fig. 3: Evolutionary power spectral analysis of terrestrial and marine δ13C record.

From: Terrestrial records of two hyperthermal events in the Cretaceous-Paleogene boundary suggest different control mechanisms

Fig. 3

Evolutionary power spectral analysis of the δ13Ccarb of Nanxiong Basin (a) and the δ13Cbulk of ODP 1262 (b) for the complete records; evolutionary power spectral analysis of the δ13Ccarb from the Nanxiong Basin for two discrete time windows: 65.85–65.0 Ma (c) and 66.6-66.0 Ma (d); evolutionary power spectral analysis of the δ13Cbulk of ODP 1262 for two discrete time windows: 65.9-65 Ma (e) and 66.6-66.0 Ma (f). Blue represents low spectral power, and yellow represents high spectral power.
