“…Existing U-Pb dates from the Umkondo LIP are quite close together in age implying the the province was emplaced rapidly (within ca. 3 million years) as is the case for some other well-constrained intraplate large magmatic events such as the Central Atlantic Magmatic Province (Blackburn et al, 2013) and the Karoo-Ferrar Province (Sell et al, 2014;Burgess et al, 2015). Notably, this magmatic history contrasts with the evidence for prolonged magmatic activity in the Keweenawan Midcontinent Rift wherein applications of paleosecular variation analyses need to be cognizant of the evidence for progressive directional change that is associated with rapid plate motion rather than secular variation (Davis & Green, 1997;Swanson-Hysell et al, 2009, 2014a.…”

“…The entire T-OAE isotopic excursion has been estimated as lasting 0.3-0.5 myr (Boulila et al 2014) or 0.6 ± 0.1 myr (Huang & Hesselbo 2014), with the two major anoxic episodes, termed T-OAE1 and T-OAE2, falling on either side of the 183 Ma age estimate (Ikeda & Hori 2014;Sell et al 2014). The substantial carbon isotopic anomaly has been explained by input of large volumes of isotopically light carbon from the Karoo-Ferrar basaltic province (Suan et al 2010;Burgess et al 2015).…”

“…However, large igneous provinces associated with the arrival of upwelling mantle plumes often result in short (~1 m.y.) pulses of intense and voluminous volcanism (e.g., Blackburn et al, 2013;Burgess et al, 2015;Renne et al, 2015). In contrast, magmatism in the Midcontinent Rift was prolonged over tens of millions of years.…”
