plutonism

A rival theory known as plutonism (or vulcanism) held that rocks were formed in fire.

These ideas supported the theories of plutonism and uniformitarianism.

Later the system was stabilised and the present continents slowly built up and extended by plutonism.

In fact, both men shared the same volcanistic, or in de Charpentier's case rather plutonism assumptions, about earth history.

AMCG plutonism is generally associated with asthenospheric upwelling under thinned lithosphere.

In the Precambrian, extensive plutonism caused metamorphism and deformation of the region that would become the Teton Range.

Darwin was rather bored by Robert Jameson's natural history course which covered geology including the debate between Neptunism and Plutonism.

His theories of geology and geologic time, also called deep time, came to be included in theories which were called plutonism and uniformitarianism.

The creation of the inner magmatic arc is characterized by terrestrial clastic deposition and the early stages of acidic volcanism and plutonism.

The first phase of regional plutonism started 210 million years ago in the late Triassic and continued throughout the Jurassic to about 150 million years BP.

Thomas Beddoes and John Hailstone were engaged in a geological controversy upon the rival merits of the Plutonism and the Neptunist hypotheses.

The main phase of plutonism was followed by localized strain and shear-zone-hosted gold mineralization, particularly in the Little Stull Lake area near the Ontario-Manitoba border.

He was one of the leading advocates of plutonism in the early debate that confronted plutonism to neptunism, making him described by some authors as an ultraplutonist.

A largely buried orogen along the western margin records amphibolite-grade deformation and granitoid plutonism at 1.35-1.2 Ga and is inferred to connect with the Namaqua belt to the south.

Hutton's innovative 1785 theory based on Plutonism visualised an endless process of rocks forming under the sea, being uplifted and tilted, then eroded to form new strata under the sea.

This is derived from the theory that AMCG plutonism is driven by ponding of olivine tholeiite basalt at the base of the continental crust during tectonic extension.

Hutton proposed the theory of Plutonism; the Earth formed through the gradual solidification of a molten mass at a slow rate by the same processes that occurred throughout history and continues in present day.

The evidence for the Acadian orogeny is abundant and widespread in the northern Appalachians, recorded by the plutonism and the migration of the northern Appalachian deformation front toward the craton.

Early Mesozoic and Neogene plutonism in Bolivia's Cordillera Central created the Bolivian tin belt as well as the famous, now depleted, deposits of Cerro Rico de Potosí.

John Henry Pepper merges Antonio Snider-Pellegrini's map, Evan Hopkins' proof of northward shifting of the continents of his neptunist book and his plutonism ( and cited in ).

However, renewed high temperatures are indicated by Superior-wide leucogranite plutonism and metamorphism (2.66-2.64 Ga), as well as regional deep crustal metamorphism and ductile, orogen-parallel flow, correlated with ubiquitous subhorizontal reflectivity.

In the central to southern Appalachians, evidence for the Acadian orogeny is poor, and is found primarily in the plutonism of the Blue Ridge and metamorphism of the Cat Square terrane.

This was one of the findings that led him to develop his theory of Plutonism and the concept of an immensely long geologic time scale with "no vestige of a beginning, no prospect of an end."

Potassium-argon ages of Neogene to Recent igneous rocks from the Halmahera region record a history of intra-oceanic arc development since the late Middle Miocene following an earlier phase of collisional plutonism.
