Abiogenic petroleum origin

The abiogenic petroleum origin hypothesis proposes that most of Earth's petroleum and natural gas deposits were formed inorganically, commonly known as abiotic oil. Scientific evidence overwhelmingly supports a biogenic origin for most of the world's petroleum deposits. Mainstream theories about the formation of hydrocarbons on Earth point to an origin…
