	Batholith - Wikipedia, the free encyclopedia
		A batholith is a large emplacement of igneous intrusive (also called plutonic) rock that forms from cooled magma deep in the Earth's crust.
		Batholiths are almost always made mostly of felsic or intermediate rock-types, such as granite, quartz monzonite, or diorite.
		One such batholith is the Sierra Nevada Batholith, which is a continuous granitic formation that forms much of the Sierra Nevadas in California.

		Batholiths form the core of some large mountain ranges like the Sierra Nevada of western North America.
		The solidified magma becomes the central axis of a rising mountain range, resulting in the deformation (folding and overthrusting) of rocks on either side.
		In the UK, a batholith underlies SW England and is exposed in places to form areas of high ground such as Dartmoor and Land's End.

		Batholiths usually are granitic (see granite) in composition, have steeply inclined walls, have no visible floors, and commonly extend over areas of thousands of square miles.
		Batholiths are formed either as one large mass or many smaller masses at great depths in the earth's crust and are exposed at the surface only after considerable erosion of the overlying mountain mass.
		One of the largest single batholiths in North America is the Coast Range batholith of W Canada and Alaska, encompassing an area of about 73,000 sq mi (182,500 sq km).

		The preserved dike swarms are almost entirely restricted to the western and eastern blocks of the batholith, contrasting with their rarity in the uplifted central block.

		batholith, enormous mass of intrusive igneous rock, that is, rock made of once-molten material that has solidified below the earth's surface (see rock).
		They are commonly associated with lithospheric plate boundaries, where the interactions between plates can produce sufficient heat to melt crustal rocks on a large scale and form batholiths (see plate tectonics).
		Important batholiths in the United States include the Idaho batholith, 18,000 sq mi (45,000 sq km), and the Sierra Nevada batholith, 16,000 sq mi (40,000 sq km).

	Mesozoic Plutonism in the Sierra Nevada Batholith

		Evidence in the Sierra Nevada batholith as described by Bateman (1988) would seem to suggest that all of these methods of emplacement were active at least in some part.
		The gabbroic to granitic intrusives of the Tehachapi Mountains represent the deepest exposures of batholithic cumulates formed at depth of 25-30 km.

		Distinctive porphyritic quartz syenite occurs in ring dikes in the western (the Mount Garfield) and the eastern (the Albany) halves of the batholith.
		Igneous activity commenced in the western batholith with emplacement of the porphyritic quartz syenite (201 Ma and 193 Ma) and the quartz porphyry (195 Ma) of center W1 and the syenite and trachyte of center W2 (193 Ma).
		The porphyritic quartz syenite is similar in appearance across the batholith but occurrences in the eastern and western parts of the batholith are distinguished as the Albany and the Mount Garfield, respectively.

		Exposure of the Idaho batholith is confined to the central region of the state and encompasses approximately 20,000 square miles.
		Subsequent post batholithic emplacement throughout the region involved Tertiary dike swarms which trend in a northeast direction and seem to be related to the metallogenic epochs within the Idaho batholith.
		The batholith is divided into two distinct lobes, the Bitterroot lobe to the north and the Atlanta lobe, including the Atlanta Project, to the south.

	A PRIMARY LITHOSPHERE SECTION FOR THE SIERRA NEVADA BATHOLITH (Site not responding. Last check: 2007-11-06)
		A primary lithosphere section is reconstructed for the Sierra Nevada batholith based on the convergence of rock types that occurs between the base of its southern oblique crustal section and batholith-related lower crust-mantle xenoliths that were entrained in Miocene lavas erupted through shallow levels of the batholith to the north.
		The upper ~35 km of the section is predominately tonalitic to granodioritic batholithic rock with subordinate wallrock screens.
		The roof of the batholith is predominately its own silicic volcanic cover, and there is no evidence for the batholith having spread out over a mid-or deep crust regional metamorphic substrate.

		The Chinamora Batholith (Zimbabwe) frequently is stated as a type-locality for the emplacement mechanism of ballooning, however its emplacement mechanism is still the subject of an ongoing discussion.
		The Chinamora Batholith is a composite batholith comprising numerous lithologies ranging from dioritic to granitic which may be grouped into the marginal gneissic granites, the equigranular granites and the central porphyritic granite.

		We infer that the Indus molasse thus records a significant proportion of the early unroofing history of the batholith.

		We propose that the compositional boundary decouples the eastern and western portions of the batholith, and that the eastern portion has thinned in response to regional Miocene extension, or Salton trough rifting, or both.
		The Mesozoic Peninsular Ranges batholith is a major component of the southern California crust between the International border and the Transverse Ranges (Fig.
		We hypothesize that the steep Moho slope under the eastern Peninsular Ranges batholith is due to the crustal thinning and rifting associated with the opening of the Gulf of California and the Salton trough.

	granite
		Most geologists now agree that the batholith owes its existence to the process of tectonic-plate convergence during which melting occurred as a consequence of subduction of oceanic lithosphere (the rigid crust and upper part of the mantle) beneath the margin of the North American continent during Mesozoic time.
		The Sierra Nevada batholith is an amalgam of many plutons of varied compositions that intruded the continental crust during subduction.
		The batholith as exposed in Yosemite Valley and regions west contains mostly Cretaceous rocks with the rocks in general becoming younger towards the east (Bateman, 1992).

	Great Stone Dome and the Global Flood
		An infinitely long batholith that is 11 km wide, 16.5 km thick, and is buried 20 km below the surface of the ground, when at zero rock permeability (that is, conductive cooling only) needs a few million years to cool.
		This was then intruded by the batholith which metamorphosed the sediments next to the stock.
		David Tyler will say that the batholith cooled off quickly, but it was originally under a mile of sediment and even if we grant that hydrothermal flow cools the batholith, according to the Creationist, Woodmorappe, such things would require about 3000 years.
