What was Abraham Gottlob Werner's theory on the Earth's origin?

German geologist Abraham Gottlob Werner proposed a late 18th-century theory of the Earth known as Neptunism, which stated that rocks formed from the crystallization of minerals in the early Earth's oceans. Named after the Roman sea god Neptune, the theory helped establish early concepts of rock stratification and geological formations. While most of its tenets were eventually set aside in favor of theories like plutonism, Werner is remembered for demonstrating chronological succession in rocks.

What we know

• Abraham Gottlob Werner proposed a history of the Earth and rock stratification that came to be known as Neptunism. [2, 3, 4]
• Neptunism posits that rocks formed from the crystallization of minerals in the early Earth's oceans. [4]
• Werner used the concept of a geologic formation during the development of his theory from 1774 until his death. [3]
• Neptunism was debated against a rival theory called plutonism, which gave a significant role to volcanic origins. [4]

Still open

• Vivianite was named by Werner in 1817 after either John Henry Vivian or Jeffrey G. Vivian, leaving some ambiguity about the exact namesake.
