The rocks are rich in organic matter (up to 30% in the biomicrite) that has provided a significant potential for spontaneous combustion. Spontaneous combustion of the bituminous marl (oil shale) in Jordan was a multiple phase metamorphism (Khoury 1989, 1993, 2006, 2012, 2014a, b, 2015; Khoury and Nassir 1982a, b; Khoury et al. 1984, 1992).The yellow biomicrite is overlain by beige-white marl layers.
