A high is in structural geology and tectonics an area where tectonic uplift has taken place relative to its surroundings. Highs are often bounded by normal fault s and can be regarded as the opposites of basin geology basins . A related word is a massif , an area where relative old rocks layers are found at the surface. A small high can be called a horst geology horst . Because of the relative uplift the accommodation space for sediments was relatively small and a high will have thinner sedimentary layers deposited on it compared to the surrounding basins. Therefore, highs are not good places to study stratigraphy stratigraphic sequences as the sequence may be less detailed or even absent. Category Tectonicstectonics stub ... more details

Deformation styles In areas of thrust tectonics two main styles are recognized thin skinned deformation and thick skinned deformation .

The interplay between erosion and tectonics has been a matter of debate since the early 1990s. While Tectonics tectonic effects on surface processes such as erosion for example, the river entrainment subsequent to a tectonic rock uplift have been long recognized, the reverse the effects of erosion on tectonic deformation has only recently been addressed thanks to the availability of computer modelling techniques. ref Willett, Sean D., et al., Tectonics, Climate and Landscape Evolution , Geological Society of America Special Paper 398, 2006 ISBN 0 8137 2398 1 http earth.geology.yale.edu brandon Eprints Willett 20etal2006GSASP390 Introduction.pdf PDF of Introduction ref Tectonics modify erosion because it modifies the surface topography , which is the most important parameter controlling surface processes of mass transport. Erosion might be reduced on a flat landscape before a normal fault generates a topographic gradient for example. Landforms are generally considered as the result of the interaction between the tectonic and isostatic uplift and the response of surface erosion. The way the tectonic deformation is influenced by erosion is more subtle and is produced by the weight of the mass removed eroded from the surface and the weight of the deposited sediments, which in some circumstances can become relevant enough as to modify the state of stress at depth and the pattern of tectonic deformation. Although originally proposed for continental collision settings, presently the effects of erosion on tectonic deformation have been extended to a diversity of tectonic settings including continental margin s, plate subduction , and high plateau s.

No footnotes date February 2011 Plume tectonics is a geophysical theory that finds its roots in the mantle doming concept which did not accept major plate movements and continental drifting which was especially popular during the 1930s, and survived throughout the seventies up till today in various forms and presentations. It has slowly evolved into a concept that recognises and accepts large scale plate motions such as envisaged by plate tectonics , but placing them in a framework where large mantle plume s are the major driving force of the system. The theory focuses on the movements of postulated mantle plumes under tectonic plate s viewing them as the major driving force of movements of parts of the Earth s crust. It tries to reconcile in one single geodynamic model the horizontalistic concept of Plate tectonics, and the verticalistic concepts of mantle plumes and Hotspot geology hot spots , together with the existence of various super continent s in Earth history. This theory has little support in mainstream geology. More plausible is the view that mantle plumes do not make an appreciable contribution to plate motions, or to volcanism on Earth s surface. ref name Foulger cite book title Plates vs. Plumes A Geological Controversy author Foulger, G.R. url http www.wiley.com WileyCDA WileyTitle productCd 1405161485.html year 2010 isbn 978 1 4051 6148 0 publisher Wiley Blackwell ref References Reflist Cite journal last Fukao first Y last2 Obayashi first2 M last3 Inoue first3 H last4 Nenbai first4 M year 1992 title Subducting slabs stagnant in the mantle transition zone journal .......97.4809F Cite journal last Maruyama first Shigenori year 1994 title Plume tectonics journal ...

Extensional tectonics is concerned with the structures formed, and the Tectonics tectonic processes associated with, the stretching of the Crust geology crust or lithosphere . Deformation styles The types of structure and the geometries formed depend on the amount of stretching involved. Stretching is generally measured using the parameter math beta math , known as the beta factor where math beta frac t 0 t 1 math , math t 0 math is the initial crustal thickness and math t 1 math is the final crustal thickness. It is also the equivalent of the Strain materials science strain parameter stretch . ref http books.google.co.uk books?id ycASqdxSG3YC&pg PA64&dq stretch Foundations of structural geology&lr &ei HjYVSrq3EZrEzASuzrH7Ag Park, R.G. 1997.

image SaltTectonics1.jpg 500px thumb right Salt tectonics is concerned with the geometries and processes associated with the presence of significant thicknesses of evaporite s containing rock salt within a stratigraphy stratigraphic sequence of rocks. This is due both to the low density of salt, which does not increase with burial, and its low strength. Passive salt structures Structures may form during continued sedimentary loading, without any external tectonic influence, due to gravitational instability. Pure halite has a density of 2160 kg m sup 3 sup . When initially deposited, sediments generally have a lower density of 2000 kg m , but with loading and compaction their density increases to 2500 kg m , which is greater than that of salt. ref McGeary.

multiple issues notability December 2009 original research December 2009 primarysources December 2009 Overview Cloud Tectonics is a one act play by Jos Rivera , a dreamlike and ultimately tragic love story about its two protagonists, An bal de la Luna and Celestina del Sol. It is set in Los Angeles , with most of the action taking place in An bal s house. It is somewhat of the archetypal boy meets girl story but it is truly told by a master of the form. Rivera puts magical realism he studied screenwriting with Gabriel Garc a M rquez at the Sundance Institute in 1989 to good use in the play by distorting our conceptions of time, space, and even although not to the same extent sound. He additionally makes use of poetic and occasionally absurd language to enhance the characters and the world of the play. Production history The play premiered at the 19th Annual Humana Festival in 1995, and was subsequently produced at the La Jolla Playhouse and later at Playwrights Horizons in NYC.
