why are the petroleum occurences in the precambrian and the pleistocene rare? Please answer urgent question
And got the following answer:
The relationship of Rock to Oil is one of host. Rock acts as a reservoir for holding petroleum, but the creation of that oil was not contemporaneous with the genesis of the rock. If you think of geology as layer cakes, the Precambrian is at the bottom. The natural migration path for petroleum is upwards as it is lighter than water. So oil does not readily "sink" to the bottom of the layer cake. Secondly, very few Precambrian rocks have a permeability that would allow petroleum to flow into it, so it makes a very poor reservoir. Any hydrocarbons that were trapped would metamorphose into graphite. There are plenty of Pleistocene occurrences of petroleum. They are called oil seeps and act as an escape valve for oil coming up from depth. Most Pleistocene deposition is of permeable rock types, so much so that they rarely trap a significant quantity within themselves. Seeps were used originally as a marker to where drilling deeper could find a host rock with a larger quantity trapped.
