Answer :
Mineral fuels may be those hydrocarbon-containing natural fossil fuel resources which are not derived entirely
from biological sources. They have high quantities of carbon. Generally, coal, petroleum, and natural gas are mineral fuels.
Mineral fuels are found in sedimentary rocks largely as these rocks form under very low temperature and pressure conditions. As the fossil sediments gets compressed into the rocks, with time and after gradual decay and dissolve of the fossil, the minerals finally seep deeply into them and finally changes the entire chemical make-up.

Mineral fuels are found in sedimentary rocks because they are porous and carbon particles can reside within them. Shale is the sedimentary rock in which oil and gas are formed. Sandstone is another type of sedimentary rock in which mineral fuels reserve.
