COVER: A series of sill intrusions in Mussentuchit Canyon, Utah (USA). The sills were emplaced at ca. 5 Ma within Middle Jurassic rocks aged ca. 165 Ma, providing a good example of the “overthickening” of overburden above petroleum source rocks by igneous intrusions, as described by Gardiner et al. in “Modeling petroleum expulsion in sedimentary basins: The importance of igneous intrusion timing and basement composition”, p. 904–908.
