Limestone.
Oil is commonly formed in rock or in sealed pockets under the seabed and it is from the Latin for 'rock oil' that the word 'Petroleum' is derived
lime stone
Sedimentary rock (limestone, slate, etc) forms when small particles sink onto the seabed, along with dead animals or plants, forming deep layers of mud. Over a very long time, the lay may be subjected to enough pressure to form sedimentary rock, encasing the fossils.
shelly seabed
easy, mining on the seabed, or mining on the bottom of the sea
International Seabed Authority was created in 1994.
Petroleum is a dark, stick and viscous liquid. It is formed by the deposition of the remains of algae and animals on the seabed. These piled up to form a sedimentary rock. The pressure hardened the rock and the bacterial activities convert it to crude. Natural gas is usually formed along with the crude oil(which may possibly be the waste product of the bacteria). The crude, being less dense moves up the rock and finally trap under the rock where it could no longer finds porous channel.
The seabed and land are connected, however ,seabed is covered with water and therefore lies largely undiscovered to man. Due to the different organisms using the land or seabed as their habitat, the mineral make-up of the two may differ.
As Methane Hydrants form at low temperature and at high pressure, they can be found on the seabed and in arctic perma-frost.
