Graptolites as fossil geo-thermometers and source material of hydrocarbons: An overview of four decades of progress
Sign Up to like & getrecommendations! Published in 2020 at "Earth-Science Reviews"
DOI: 10.1016/j.earscirev.2019.103000
Abstract: Abstract The thermal maturity of lower Paleozoic graptolite-bearing marine sediments, which host many hydrocarbon deposits worldwide, has long been difficult to determine due to the absence of wood-derived vitrinite particles for conventional vitrinite reflectance. In… read more here.
