As others before him, Folk proposed a classification for sandstones based on the relative abundances of quartz (Q), feldspars (F), and rock fragments (R). These are the main poles of the classification diagram. To define the clan name one must normalize the sum of abundances of quartz, feldspars and rock fragments to 100%.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 nonconventional hydrocarbon potential of the Cretaceous Colombian back-arc basin is explored taking into consideration the properties of fine-grained units, including biomicrite, marlstone, and shale, in terms of total organic carbon content, gas content, vitrinite reflectance, porosity, permeability, pyrolysis, and organic geochemistry of ...

It is a form of cross-bedding usually formed by the action of large storms, such as hurricanes. It takes the form of a series of "smile"-like shapes, crosscutting each other. It is only formed at a depth of water below fair-weather wave base and above storm ...Under the Dunham classification (Dunham, 1962 [1]) system of limestones, a packstone is defined as a grain-supported carbonate rock that contains 1% or more mud-grade fraction. This definition has been clarified by Lokier and Al Junaibi (2016) [2] as a carbonate-dominated lithology containing carbonate mud (<63 μm) in a fabric supported by a ...
