Molecular parameters of maturation in the Toarcian shales, Paris Basin, France—III. Changes in aromatic steroid hydrocarbons☆
TL;DR: In this article, three series of monoaromatic steroid hydrocarbons (basepeak = m/z 239, 253 and 267) and four series of triaromatic sterols (base peak =m/z 217, 231, 245 and 259) have been recognized by computerized gas chromatography-mass spectrometry in a variety of samples of Lower Toarcian shales from the Paris Basin.
