Instead, it becomes buried under layers of mud and silt, creating a carbon-rich sludge known as kerogen, which is the fundamental building block of fossil fuels. With increasing depth comes increasing temperature and pressure.
Heat Pressure Time: The Transformation of Organic Matter into Oil
Organic Material: The Starting Ingredient The journey of oil begins long before rock layers can trap it. Oxygen-poor, or anoxic, basins on the sea floor prevent bacteria from fully breaking down the matter.
Accumulation Dead organisms settle on the sea floor. Anoxic environment, high sedimentation rate.
Heat Pressure Time: The Transformation of Organic Matter into Oil
Transformation Kerogen converts into hydrocarbons. Anoxic conditions are often found in deep ocean floors or stagnant lagoons, where the lack of water circulation keeps the biological matter intact long enough for burial.
