The Rock-Eval pyrolysis parameter [S.sub.1] values vary between 0.04 and 16.16 mg HC/g rock (average 5.26 mg HC/g rock) for bituminous rock samples, whereas the Rock-Eval pyrolysis parameter [S.sub.2] values for the samples range from 0.07 to 115.56 mg HC/g rock (average 38.42 mg HC/g rock).
PY values for the investigated bituminous rock samples are usually high, ranging from 110 to 131 720 ppm (average 43 674.5 ppm).
(6) 10-14 cm greyish-brown to dark brown bituminous mudstone containing accumulations of shelly faunas in the lower part and microlaminated, seemingly bituminous rock
in the upper part.
Alternatively, the puzzling presence could in some way be related to transport from an adjacent bituminous rock (or to a joke by a malicious mineral collector).
also determined that there are no reported occurrences of bituminous rocks, which could possibly release the compound, at the contact or in proximity of the "Garofiro" around the mine.
However, geological studies have demonstrated that Morocco ranks seventh in bituminous rock reserves in the world with an estimated 50 billion barrels of oil of bituminous rock deposits found in the northern, central and southern regions of the country .
During the past few decades, there has been an increasing interest in the utilization of these bituminous rock deposits as an alternative energy source .
Kazakhstan mainly exports wheat, oil products obtained from bituminous rocks
and rolled iron.
With an energy sector dominated by a single primary source of energy, shale oil from its bituminous rocks
, Estonia is the exception rather than the rule in the EU.
1991, 1999), the CM of sedimentary rocks of the Hatrurim basin was due to internal combustion of the bituminous rocks
. The extensive combustion caused a high-temperature low-pressure metamorphism followed by consequent retrograde alterations (hydration, carbonization, and sulphatization).
<p>The country is aiming mainly to secure the energy supplies through diversifying resources, she said, noting that Moroccans' consumption of electricity is expected to quadruple by 2030.aaMorocco is now turning towards using gas as an important energy source, either through the Maghreb-Europe gas pipeline, or the liquefied natural gas (LNG).aa She did not rule out the possibility of resorting to the nuclear energy, and the promotion of bituminous rocks
, with the creation of a 100-MW electricity plant in the southern region of Tarfaya.
