" ... Recent research has identified a global warming event that occurred several hundred thousand years before the end-Cretaceous extinction. Some scientists have linked the eruption of the Deccan Traps to this warming event, but there is debate over whether the lavas that erupted could have released enough CO2 into the atmosphere to cause it. Adding to this mystery, the lava volumes that erupted during this time are relatively small compared to the volumes erupted during subsequent stages of Deccan Traps activity. A major challenge in this debate has been the lack of CO2 data on Deccan magmas from this time. ... "
" ... The lavas probably weren't all that different to those that make up the Hawaiian island volcanoes, says Byrne. There was just more of them, and they erupted over much, much longer timescales than on Earth, hence the bigger volcanoes, he says. ... "
" ... The second factor involves chemistry. The first lavas that were erupted during this sequence were all of a chemical composition assumed to be left over from the 1955 eruption. That magma had been stored underground since 1955, and during that time had been aging, degassing and crystallizing. The result is that makes it stickier, more viscous, harder to move, and resistant to flow. For all those reasons, it took a lot of work to squeeze that magma out. We saw that reflected with seismic and deformation data. ... "
" ... Time sequence of lunar mare -- lava plain -- flows in 0.5 billion year time increments, with red... [+] areas in each time step denoting the most recently erupted lavas. The timing of the eruptions, along with how much lava was erupted, helped scientists determine that the Moon once had an atmosphere and that the lunar atmosphere was thickest about 3.5 billion years ago.
