2. Igneous rock - Wikipedia

   en.wikipedia.org/wiki/Igneous_rock

   Igneous rock (igneous from Latin igneus 'fiery'), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet 's mantle or crust.

3. Large igneous province - Wikipedia

   en.wikipedia.org/wiki/Large_igneous_province

   A large igneous province (LIP) is an extremely large accumulation of igneous rocks, including intrusive (sills, dikes) and extrusive (lava flows, tephra deposits), arising when magma travels through the crust towards the surface. The formation of LIPs is variously attributed to mantle plumes or to processes associated with divergent plate ...

4. Bushveld Igneous Complex - Wikipedia

   en.wikipedia.org/wiki/Bushveld_Igneous_Complex

   Bushveld Igneous Complex geologic map and mine locations. The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion [1] [2] within the Earth's crust. [3] It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin.

5. St. Francois Mountains - Wikipedia

   en.wikipedia.org/wiki/St._Francois_Mountains

   The igneous rocks of the Saint Francois Mts. are interpreted to be a series of caldera complexes, [8] similar in scale to the Yellowstone Caldera complex. However, it is debated whether the igneous activity was related to a hotspot, like Yellowstone, or whether it was related to an ancient subduction zone. [citation needed]

6. Canadian Shield - Wikipedia

   en.wikipedia.org/wiki/Canadian_Shield

   The Canadian Shield (French: Bouclier canadien [buklje kanadjɛ̃]), also called the Laurentian Shield or the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent.

7. List of rock types - Wikipedia

   en.wikipedia.org/wiki/List_of_rock_types

   Claystone – Clastic sedimentary rock composed primarily of clay-sized particles. Coal – Combustible sedimentary rock composed primarily of carbon. Conglomerate – Sedimentary rock composed of smaller rock fragments. Coquina – Sedimentary rock that is composed mostly of fragments of shells.

8. North Atlantic Igneous Province - Wikipedia

   en.wikipedia.org/wiki/North_Atlantic_Igneous...

   The North Atlantic Igneous Province (NAIP) is a large igneous province in the North Atlantic, centered on Iceland.In the Paleogene, the province formed the Thulean Plateau, a large basaltic lava plain, [1] which extended over at least 1.3 million km 2 (500 thousand sq mi) in area and 6.6 million km 3 (1.6 million cu mi) in volume. [2]

9. Magmatism - Wikipedia

   en.wikipedia.org/wiki/Magmatism

   Magmatism. Geological map showing the Gangdese batholith, which is a product of magmatic activity about 100 million years ago. Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. It does so through magmatic activity or igneous activity, the production ...
