“…A shorter 30-to 35-million-year period (more pronounced during the last 135 million years) was also detected in the ages of LIPs (Figure 2b). These wavelet analysis results agree with Fourier analyses reported in Prokoph et al [2013].…”

“…In addition, the discovery of the 62-million-year cycle in the marine strontium-and sulfur-isotope records [Melott et al, 2012;Prokoph et al, 2013] supports the conclusion that the period is not the result of sampling, as proposed by Smith and McGowan [2005]. The three cycles seen in the LIP eruptions and fossil diversity are negatively correlated; that is, times of high production of lava are generally times of low fossil diversity.…”

“…An additional period of roughly 35 million years was also detected in these data, especially over the last 135 million years (since the early Cretaceous). In the case of the LIP ages, wavelet analysis by Prokoph et al [2013] similarly detected a cycle of about 62 million years and a somewhat weaker 140-million-year cycle. A shorter 30-to 35-million-year period (more pronounced during the last 135 million years) was also detected in the ages of LIPs (Figure 2b).…”

“…To test the idea that mantle plume activity follows cycles, Prokoph et al [2013] chose to search for regular periods in LIP eruptions. They applied continuous wavelet transform analysis to the fossil diversity data of Rohde and Muller [2005] and also to data on the probability distribution of the ages of known LIP events [Courtillot and Renne, 2003] (Figure 1).…”

“…It is difficult to provide a firm answer because, to date, no data confirm a frequency transition in the 9-My cycle. In addition, Japanese data suggest that this disturbance in orbital forcing started much earlier, so that this 25-My-long phenomenon would have exactly prevailed from the Central Atlantic magmatic province flood basalt events to the Karoo-Ferrar eruptions (29) (Figs. 1B and 3G).…”

Eccentricity, obliquity, and precession are cyclic parameters of the Earth's orbit whose climatic implications have been widely demonstrated on recent and short time intervals. Amplitude modulations of these parameters on million-year time scales induce "grand orbital cycles," but the behavior and the paleoenvironmental consequences of these cycles remain debated for the Mesozoic owing to the chaotic diffusion of the solar system in the past. Here, we test for these cycles from the Jurassic to the Early Cretaceous by analyzing new stable isotope datasets reflecting fluctuations in the carbon cycle and seawater temperatures. Our results document a prominent cyclicity of ∼9 My in the carbon cycle paced by changes in the seasonal dynamics of hydrological processes and long-term sea level fluctuations. These paleoenvironmental changes are linked to a great eccentricity cycle consistent with astronomical solutions. The orbital forcing signal was mainly amplified by cumulative sequestration of organic matter in the boreal wetlands under greenhouse conditions. Finally, we show that the ∼9-My cycle faded during the Pliensbachian, which could either reflect major paleoenvironmental disturbances or a chaotic transition affecting this cycle.orbital cycles | carbon cycle | paleoclimate | eustatism | Mesozoic

In the past few years, researchers have uncovered evidence that several kinds of geological and biological events seem to show regular cycles of similar lengths. For example, Rohde and Muller [2005] looked at the record of diversity of marine organisms over the past 540 million years and found evidence for two cycles in the data—a roughly 62‐million‐year cycle and a longer cycle of about 140 million years. This was followed by reports of an approximately 56‐million‐year cycle in long‐term stratigraphic sequences in sedimentary basins [Meyers and Peters, 2011] and a 59‐million‐year period in the marine strontium‐isotope record [Melott et al., 2012]. A similar period may even exist in atmospheric carbon dioxide over the past 542 million years of the Phanerozoic [Franks et al., 2012]. A cycle of about 140 million years was reported by Veizer et al. [2000] and Mayhew et al. [2008] in long‐term fluctuations in global climate.
