	Electrically heated glass forehearth - Patent 4247733
		The zones within the forehearth are preferably maintained at temperatures which differ from one another, and a baffle 12 may be provided between zones A, B and C to isolate this difference in temperature is maintained for the glass 14 flowing through the channel 10.
		The conductivity for the molten glass for each of the zones A, B and C is measured throughout the downstream half of each zone and more particularly by an ammeter A fed from a current transformer associated with the electrodes 25, 27 and 29 at the downstream end of each of these zones.
		In the same illustration however the center electrode 28 in zone C was not centered between its common electrodes 27 and 29, but was spaced a distance of 28 inches from the upstream electrode 27, and 26 inches from the downstream electrode 29 to allow for its shorter length.

	Liquid encapsulated zone melting crystal growth method and apparatus - Patent 5007980
		A floating molten zone held in place by surface tension was established in a central section of the rod, but the ends of the feed rod were never melted.
		By maintaining a molten region within the spike zone which is considerably shorter in length than the lengths of the surrounding upper and lower furnace zones, the resulting growth interface shape is slightly convex with respect to the solid phase of the material, and an optimal single crystal can be grown.
		The molten zone is repeatedly reestablished at the interface between the seed crystal and the GaAs compound material, and is traversed across the GaAs material.

	Molten Core Model for Hawaiian Rift Zones
		This "molten core", extending at least 40 km from the summit, transmits pressure and transports magma to the distal portions of the rift zone.
		A molten core within Kilauea's ERZ was first suggested by Eaton and Murata (1960) in order to explain how a dike intrusion and surface eruption in the lower east rift zone in 1960 could have been triggered and fed from the summit reservoir more than 40 kilometers away, without also producing earthquakes along the route.
		The SWRZ and ERZ of Kilauea served as the zone of separation between the south flank slide block and the remainder of the island during the November 1975 earthquake (Lipman et al., 1985).

	Summary: Volcanic Patterns, General
		Volcanic landforms result when molten rock is forced to the earth's surface through weak zones in the crust, and extruded in a variety of forms and by a variety of means.
		Weak zones, i.e., cracks, joints, and faults, are most frequently associated with tectonic forces; which accounts for the alignment of many volcanic features along plate boundaries.
		Depending on source, location, pressure and temperature relations, and the surrounding matrix, the molten rock is a varied mix of mineral entities, gases, water vapor, and chunks of local rock torn off and captured during passage through the crust.

		At subduction zones, molten rock rises, pushing two plates apart and adding new material at their edges.
		Subduction zones are those where one plate overrides, or plunges under (subducts), another, pushing it downward into the mantle where it melts.
		Indeed, major earthquakes occur only at subduction zones, the Sumatra quake at the Sunda subduction zone being the biggest mega thrust event in recent times, the likes of which are unlikely to occur for centuries perhaps.

	The Subduction Factory Science Plan
		Criteria for selection of subduction zones to be studied include the following: the margin should provide ample volcanic and seismic activity, accessibility to both input and output, along-strike variations in forcing functions, cross-arc and historical perspectives, minimal upper plate contamination of magmas, and ability to address the primary science objectives.
		The behavior of material through the upper 40 km of the subduction zone is intimately linked to the nature of the incoming sediment and rock sequence, its compaction dewatering, diagenesis and cementation, fore-arc deformation, and the nature of the seismogenic zone.
		Because subduction zones are among the most complex components of the solid earth system, achieving this goal will require a coordinated effort by a wide range of earth scientists interacting as members of an interdisciplinary team.

	The Nature of Volcanoes
		Driven by buoyancy and gas pressure the molten rock, which is lighter than the surrounding solid rock forces its way upward and may ultimately break though zones of weaknesses in the Earth's crust.
		If so, an eruption begins, and the molten rock may pour from the vent as non-explosive lava flows, or may shoot violently into the air as dense clouds of lava fragments.
		Molten rock below the surface of the Earth that rises in volcanic vents is known as magma, but after it erupts from a volcano it is called Clava.

	Woods Hole Oceanographic Institution (WHOI) - 2002 Annual Report
		Molten rock and hot fluids rise through the rock, creating additional melt.
		Traditional thermal models, left, of subduction zones assumed a rigid plate atop a constant viscosity mantle wedge, leading to cooler temperatures at shallower levels than a model produced by WHOI Senior Scientist Peter Kelemen and colleagues.
		This simple modification of subduction zone models has resolved a decades-old paradox and significantly improved our understanding of arc volcanism.

		Since molten or partially molten rock bodies (magmas) are lighter than solid rock, the magmas ascend buoyantly through the crust.
		Open fault zones, fractures and fracture intersections, contacts between different rock types and shattered zones produced by hydraulic fracturing, and mineral growth areas in rocks all lead to varying degrees of permeability.
		There is typically an upflow zone at the center of each convection cell, an outflow zone or plume of heated water moving laterally away from the center of the system, and a downflow zone where recharge water is actively moving downward.

	Geologic Hazards
		At spreading zones, molten rock rises, pushing two plates apart and adding new material at their edges.
		Subduction zones are found where one plate overrides, or subducts, another, pushing it downward into the mantle where it melts.
		Subduction zones are characterized by deep-ocean trenches, shallow to deep earthquakes, and mountain ranges containing active volcanoes.

	Junction Transistor Manufacture
		The impurities collect in the molten zones and are swept to one end of the bar.
		The molten indium penetrates the germanium to form an alloy of p-type germanium which is in intimate contact with the n-type base material.
		The furnace is divided into three temperature-controlled zones, the temperatures being controlled to within ±1°C on temperatures of the order of 650 °C. This close control is necessary because the depth of alloying, and hence the effective thickness of the base, depends on the furnace temperature.

	Earth's Core-Mantle Boundary Has Core-Rigidity Zone
		The nature of the core-mantle boundary is important because researchers now think it influences phenomena ranging from the behavior of Earth's magnetic field to the massive plumes of hot rock that rise through the mantle and erupt on the surface at volcanic hot spots such as Hawaii.
		In the 1990s, seismic tomography showed the existence of "ultra-low velocity zones" at the base of the mantle, which some scientists interpret as evidence of partial melting of the mantle.
		Rost, a postdoctoral researcher, said an ultra-low velocity zone overlaps the area where he detected a core-rigidity zone, but that doesn't necessarily mean there is a connection between the two.

	NOAA Ocean Explorer: Submarine Ring of Fire
		This multi-year project aims to explore submarine volcanoes within the Ring of Fire in two very different tectonic settings on either side of the Pacific—one in which new seafloor is created and the other in which old seafloor is destroyed.
		Where tectonic plates are moving apart, molten rock—magma—rises up from deep within the Earth to fill the gap, and in doing so, creates new ocean floor.
		At subduction zones, the plate that is forced downward dives back into the Earth and is eventually melted and recycled.

	Paul Hall Research: Subduction Zones (Site not responding. Last check: 2007-10-31)
		Volcanism associated with the subduction of oceanic lithosphere is the primary source of new continental crust and as such is a significant contributor to the chemical differentiation of the crust-mantle system.
		Several conceptual models have been proposed to descibe melt transport at subduction zones, including diapiric flow of a hydrous or partially molten component, distributed porous flow of magma and magma flow through fractures.
		The experiments demonstrated that the diapiric flow model is capable of producing a wide range of transport times, depending on the flux of buoyant fluid (i.e., partially molten material) into the system at depth and the rate of subduction.

	About Flash Butt Welding
		The net effect of this extra time in the molten state is a metallurgically strong weld that is relatively free of harmful impurities.
		After learning the basic dynamics of flash welding, and why it is important to have wide molten regions at the blade ends during welding, some other factors must be understood that cause the molten zones to be too small or too cold.
		The width of the heat-affected zone generally is just smaller than the width of the jaws during annealing, and it should be parallel to the weld area from the tooth edge to the back edge.

	Volcano (Site not responding. Last check: 2007-10-31)
		For other meanings of the word eruption, see eruption (disambiguation)'' ---- A volcano is a geological landform (usually a mountain) where magma (rock of the earth's interior made molten or liquid by high pressure and temperature) erupts through the surface of the planet.
		Although there are numerous volcanoes (some very active) on the solar system's rocky planets and moons, on Earth at least, this phenomenon tends to occur near the boundaries of the continental plates.
		Their magmas are typically "calc-alkaline" as a result of their origins in the upper parts of altered ocean plate materials, mixed with sediments, and processed through variable thicknesses of more-or-less continental crust.

		Pyroclastic flows (ignimbrites) are highly hazardous products of such volcanoes, since they are composed of molten volcanic ash too heavy to go up into the atmosphere, so they hug the volcano's slopes and travel far from their vents during large eruptions.
		Temperatures as high as 1,200 °C are known to occur in pyroclastic flows, which will incinerate everything flammable in their path and thick layers of hot pyroclastic flow deposits can be laid down, often up to many meters thick.
		Volcanic action was often attributed to chemical reactions and a thin layer of molten rock near the surface.

	t42d in fm03
		To date, the primary emphasis in the physical characterisation of molten peridotite has been the determination of a PVT equation of state with contributions from shock-wave and buoyancy studies.
		Temperatures in some parts of subduction zone upper mantle are likely significantly lower than $\sim$1500 K. Consequently, it is crucial to extend these previous studies to lower temperatures and compare these results with microstructures of naturally deformed peridotites from collision zones which were likely deformed at low temperature conditions.
		A distinct low seismicity zone in the Japan Trench region, aseismicity beneath central Oregon, and other aseismic zones in mantle wedges may be attributable to "superplastic" flow under low stresses within the ultra-fine-grained dehydration products in dehydration-induced fault zones.

		Molten aluminum-thermite reactions could explain the rapid intensification of the fires and the many detonations seen and heard moments before and during the collapse of each Tower.
		We observed that the temperature of the molten aluminum in contact with the pre-heated rusty iron simply cooled at about 25 C per minute until the aluminum solidified, so that any thermite reactions between the aluminum and iron oxide must have been minimal and did not compete with radiative and conductive cooling.

	Yellowstone Caldera
		The ring fractures were a surface expression of a huge body of magma or molten rock, forming in upper levels of the earth's crust.
		Near the northeast part of the caldera, seismic velocities are even lower to within about 2 miles of the surface; this may indicate a more continuous magma body that extends from the northeastern part of the caldera to about 10 miles beyond it.
		These conditions are consistent with a large, partly molten magma body at shallow depth that extends northeast of the caldera rim.
