NEPTUNISM Meaning and
Definition
-
Neptunism refers to the geological theory that suggests that all rocks were formed by the deposition of minerals from a universal ocean. The term "neptunism" is derived from Neptune, the Roman god of the sea, alluding to the idea that the Earth was once entirely covered by water. This theory was prevalent during the late 18th and early 19th centuries before being largely discredited by the emerging science of geology.
According to the principles of neptunism, all rocks, including igneous, sedimentary, and metamorphic, were believed to have originated from the precipitation and consolidation of minerals from a primeval ocean. Neptunists postulated that these minerals gradually accumulated over time, solidifying into layers to form the Earth's crust. They attributed the formation of various rock types, such as granite and basalt, to the crystallization of dissolved minerals in this ancient marine environment.
However, the rise of the plutonist theory, proposed by James Hutton and others, challenged the neptunist perspective by introducing the concept of molten rock beneath the Earth's surface. Plutonism, later known as the igneous theory, argued that rocks were formed through the solidification of magma or lava, and not solely from the deposition of minerals in water.
Ultimately, neptunism lost relevance as further scientific inquiry and observation revealed substantial evidence supporting the igneous theory. The acceptance of the concept of plate tectonics in the 20th century further dispelled the notion of a global ocean covering the entire Earth's surface, solidifying neptunism as an antiquated geological theory.

Etymology of NEPTUNISM
The word "neptunism" originated from the Latin term "Neptunus", which means "Neptune" – the Roman god of the sea. This term was first used in the late 18th century to describe a geological theory that attributed the formation of rocks and minerals to deposition from a primal ocean, similar to the role of Neptune and his domain. The theory posited that the Earth was once completely covered by a vast ocean and that sedimentation from this ancient sea was responsible for the formation of all rocks and minerals. Therefore, the etymology of the word "neptunism" is directly derived from the god Neptune and his association with the sea.
