The former implies the enlargement of a lava dome due to the influx of magma into the dome interior, and the latter refers to discrete lobes of lava emplaced upon the surface of the dome. [2] It is the high viscosity of the lava that prevents it from flowing far from the vent from which it extrudes, creating a dome-like shape of sticky lava ...
Lava domes are common features on volcanoes around the world. Lava domes are known to exist on plate margins as well as in intra-arc hotspots, and on heights above 6000 m and in the sea floor. [1] Individual lava domes and volcanoes featuring lava domes are listed below.
Puy de Dôme (US: / ˌ p w iː d ə ˈ d oʊ m /, [3] French: [pɥi də dom] ⓘ) [4] is a lava dome and one of the youngest volcanoes in the Chaîne des Puys region of Massif Central in central France. This chain of volcanoes including numerous cinder cones, lava domes and maars is far from the edge of any tectonic plate. [5]
Chillahuita is a dacitic lava dome in northern Chile. It may have formed after the Pleistocene, [2] although argon-argon dating on amphibole has indicated an age of 370,000 ± 40,000 years; [3] another age estimate is 107,800 ± 6,400 years. [4] It has an altitude of about 4,750 metres (15,580 ft). It formed in a single non-explosive eruption. [5]
Lava dome, a mound-shaped growth resulting from the eruption of high-silica lava from a volcano; Lunar dome, a type of shield volcano found on the surface of the Earth's moon; Resurgent dome, a volcanic dome that is swelling or rising due to movement in the magma chamber; Salt dome, formed when a thick bed of evaporite minerals (mainly salt, or ...
A lava spine (or lava spire) is a vertical growth of solid lava that is forced from a volcanic vent. A lava spine can either be formed by viscous lava slowly being pushed out of the vent, or by magma that has solidified within the vent before being pushed out.

For example, endogenous substances, and endogenous processes are those that originate within a living system (e.g. an organism or a cell). For instance, estradiol is an endogenous estrogen hormone produced within the body, whereas ethinylestradiol is an exogenous synthetic estrogen, commonly used in birth control pills .
