Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

Abstract

This chapter summarizes geochronologic and other data for major Phanerozoic Large Igneous Provinces (LIPs), Oceanic Anoxic Events (OAEs) and organic-rich petroleum source rocks. It also evaluates the models that support or refute genetic links between the three groups. The evidence appears to favor genetic links between the three groups, however, additional high precision age and geochemical data are needed to validate several events. Furthermore, the chapter provides insights into the importance of LIPs in hydrocarbon exploration.

When and why the Neo-Tethyan subduction initiated along the Eurasian margin: a case study from a Jurassic eclogite in southern Iran

“…The one-way mega-transferring of continents from south to north was a key event of Earth, that occurred during the last 500 million years (Myr), with the Australian continent moving north at a rate of 70 mm/year as a representative active example (DeMets et al, 2010). During this mega-transferring of continents, the sea-land paleogeography changed, which influenced the Earth's surface temperature from an icy to a warmer world (Merdith et al, 2019;Bergman et al, 2021;Scotese et al, 2021). However, the driving mechanism for this one-way/single-directed transfer is still debated.…”
