Distribution and origin of sulfur in Colorado oil shale ...

In one core hole, the average sulfur content of a sequence of oil shale 555 m thick, which represents nearly the maximum thickness of oil shale in the basin, is 0.76 weight percent. The vertical distribution of sulfur through the oil shale is cyclic. As many as 25 sulfur cycles have lateral continuity and can be traced between the core holes.

Greenish-gray shale and shaly mudstone is pyritic, silty, and locally concretionary. Illite is the chief clay mineral and muscovite is common. Upon weathering, the shale slakes to yellowish gray clay, less resistant than the weathered black shale, and commonly produces recessive layers which are readily covered by talus from overlying units.

data), and consist of interbedded carbonaceous silty shale, dolomitic clayey shale, and siltstone. In siltstone layers, dolomite crystals with rounded impure cores suggest a detrital dolomite component. Detrital silt and mud sized dolomite was probably swept into the basin from dolomitic mudflats along the basin margin (Schieber, 1992a).

Small carbonaceous fossil - Wikipedia

Small carbonaceous fossils (SCFs) are sub-millimetric organic remains of organisms preserved in sedimentary strata.. The category of fossils includes robust or thick-walled entities such as plant spores, acritarchs and chitinozoa, but the most interesting components are fragile remnants of animals that can only be extracted through a delicate maceration technique.

Oil shale - Wikipedia

Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced, called shale oil (not to be confused with tight oil—crude oil occurring naturally in shales).

Jul 21, 2015· As such carbonaceous sediments have not been observed in any modern oceanic environments, obviously, in this case, the present cannot be the key to the past. During the Cretaceous Period, black shale deposition occurred mainly during the early Aptian and around the Cenomanian–Turonian boundary.
