	Llano Uplift - Wikipedia, the free encyclopedia
		The Llano Uplift is a formation of Precambrian rock, primarily granite, in Central Texas in the United States.
		The area is termed an uplift due to the raised status of the Precambrian rocks in comparison to adjacent, completely buried Precambrian strata.
		The ancient faulting that produced the Llano Uplift is believed to be related to that which produced the Marathon Uplift in west Texas.

		Uplift is responsible for the shapes of some geological basins, valleys, mountain lakes, canyons and it may alter soil patterns and affect earthquake intensity.
		The Himalayas were (and are still being) formed by the uplifting of two continental plates, the Indian and plates, which are colliding with each other.
		In science fiction, an uplift is a common but by no means universal term for the act of an advanced civilization helping the development of another species by bringing a non-sapient one into sentience, or by giving a sapient one spacefaring capabilities.

	Llano River - Wikipedia, the free encyclopedia
		The Llano River (LAN-no) is a tributary of the Colorado River, approximately 105 mi (169 km) long, in central Texas in the United States.
		It is formed in central Kimble County, approximately 4 mi (6 km) northwest of Junction, by the confluence of the North Llano and South Llano rivers, both of which rise on the Edwards Plateau north of the Rio Grande.
		It flows generally ENE across the Llano Uplift, a basin on the west edge of the Hill Country, through rural Mason and Llano counties, passing north of Enchanted Rock and through the town of Llano.

	Handbook of Texas Online: GEOLOGY
		Uplift of mountains, inundation by vast inland seas, river transport of large volumes of eroded sediment, volcanic eruption, and earthquake activity are all processes that have been active throughout the geologic development of Texas.
		During the early phase of the Ouachitan tectonic cycle in the Cambrian Period of the early Paleozoic, rifting of the southern margin of the ancient North American continent led to the development of a marine basin to the southeast, along with several failed rift basins, which are elongated troughs extending inland from the continental margin.
		At the end of the Mesozoic Era and the beginning of the Cenozoic Era, major uplift and mountain building in the western United States during the Laramide Orogeny affected the southwestern and western border regions of Texas.

	The Llano: From Limestone to Granite

		Among the Llano valley's natives, of course, more than a few would like to see development thrive on any terms, for it is not hard to yearn for change if you dwell in tough country that doesn't often compensate hard work with wealth.

	TECTONIC EVOLUTION OF THE WESTERN LLANO UPLIFT, CENTRAL TEXAS: A RECORD OF GRENVILLE OROGENESIS ALONG THE SOUTHERN ... (Site not responding. Last check: 2007-10-09)
		Mesoproterozoic metamorphic rocks exposed in the Llano Uplift, central Texas, were involved in a ~1150-1116 Ma Ga Grenville-age orogenic event along the southern margin of Laurentia.
		Also, no mylonite zones separate major lithotectonic domains in the western uplift, unlike the eastern uplift, and the general direction of tectonic transport is southwest, opposite that of the eastern uplift.
		We propose that the kinematics of the deformation in the eastern uplift was directly related to the northeastward collision of the arc terrane with the generally east-trending Laurentian margin, whereas deformation in the western uplift was controlled by collision of a southern continental block.

	COLLISIONAL MODEL FOR A GRENVILLE-AGED OROGENIC BELT: LLANO UPLIFT, CENTRAL TEXAS (Site not responding. Last check: 2007-10-09)
		The Llano uplift of central Texas exposes the core of a collisional orogenic belt that formed along the southern margin of Laurentia during Grenville time.
		A collisional model is proposed that reconciles differences in structural stacking, apparent tectonic transport, and deformation conditions between the eastern and western portions of the uplift.
		Our model suggests that the Llano uplift exposes different segments of the orogenic belt, and most likely different crustal levels, and records different parts of the overall Grenville orogenic history along the southern margin of Laurentia.
