Quizplus · Accepted Answer

Volcanic rock is not required for an oil or gas deposit to form. Source rock, cap rock, and reservoir rock are essential components of an oil or gas deposit. Source rock is where the oil or gas originates from, cap rock is a impermeable layer above the reservoir rock that traps the oil or gas in place, and reservoir rock is a porous and permeable rock that acts as a storage unit for the oil or gas. Volcanic rock does not play a role in the formation of oil or gas deposits.
