If possible, I am willing to help and participate in the discussion. My research is similar to yours. I am very concerned about the research and progress of global LIPs.
Dear Liu: in southern Venezuela, and spanning parts of northern Brazil, , eastern Colombia, Guyana, and Surinam (a total area of over 2 million km2), we have a LIP, but its age is around 1.8 Ga, Proterozoic, so there are no basalt plateaus left, but an array of very large (up to 10,000 km2) and thick (up to 400-600 m) diabase sills with the corresponding swarm of deep feeding dykes (one of them is over 250 km long, and has a thickness estimated in 60-80 m). It is called the Avanavero-Roraima Magmatic Province. Surely younger LIP's, like the Siberian and the Deccan trapps, and the Paraná-Etendeka are much better exposed and preserved, and could have affected greatly the climate, and even cause mass extinctions.
Regards, Sebastián.
