 What is Plate Tectonics?
Plate tectonics is the study of how the Earth's plates are driven and shaped by geological forces that keep them in constant motion.
A thin oceanic plate converging with a thick continental plate will be pushed beneath the continental plate, creating a subduction zone -- an area marked by a deep submarine trench where the oceanic plate is being driven downwards, eventually returning to the molten mantle.
This plate moves northwesterly at a rate of about 2 inches (5 cm) per year, while the North American plate on the opposite side of the San Andreas fault is moving in a southerly direction.

 Plate Tectonics - MSN Encarta
Early in the plate tectonic revolution, geologists proposed that transform faults were a new class of fault because they “transformed” plate motions from one plate boundary to another.
As a transform plate boundary cuts perpendicularly across the edges of the continental crust near the borders of the continental and oceanic crust, the result is a system such as the San Andreas transform fault system in California.
The African plate is splitting into two plates and moving away from the Arabian plate as the Red Sea meets the Gulf of Aden.

 Plate Tectonics - Crystalinks
The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which "float" on the fluid-like asthenosphere.
Tectonic plates are comprised of two types of lithosphere: continental and oceanic lithospheres; for example, the African Plate includes the continent and parts of the floor of the Atlantic and Indian Oceans.
Tectonic plates across the globe are constantly shifting - though slowly, usually by a few centimetres a year - with the magma beneath the crust.

Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear.
Even though the Nazca Plate as a whole is sinking smoothly and continuously into the trench, the deepest part of the subducting plate breaks into smaller pieces that become locked in place for long periods of time before suddenly moving to generate large earthquakes.
Land on the west side of the fault zone (on the Pacific Plate) is moving in a northwesterly direction relative to the land on the east side of the fault zone (on the North American Plate).

This movement of continental plates continues today and some plates, such as the Arabian continental plate drifting away from Africa, travel at a rate of 5 centimetres a year.
At the margins of these plates there are two types of phenomena; "active" events caused by colliding plates and "passive" events where the plates are spreading apart.
Material of an oceanic plate is more dense than that of a continental plate, so that when the two collide the oceanic plate is forced beneath the continental plate.

 Plate Tectonics, the Cause of Earthquakes
The plates consist of an outer layer of the Earth, the lithosphere, which is cool enough to behave as a more or less rigid shell.
Plate boundaries in different localities are subject to different inter-plate stresses, producing these three types of earthquakes.
The numerous north-south mountain ranges that dominate the landscape from Reno to Salt Lake City are the consequence of substantial east-west extension, in which the total extension may be as much as a factor of two over the past 20 million years.

Paleozoic Hydrocarbon Habitat in the Arabian Plate, by Abdulkader M. Afifi, #10075 (2004).
The main challenges to exploration and development are: (1) the difficulties in seismic imaging of the Paleozoic section due to multiples, seismic transparency, and near-surface problems; (2) the prediction of porosity in the tight, deeply buried reservoirs; and (3) the hostile subsurface environments.
During the Paleozoic, the plate was affected by drift and rotation that resulted in changes from equatorial to high southern latitudes and back to equatorial (at the end of the Triassic), with two periods of glaciation (Figure 2).

The Oman Mountains represent the the margin of the Arabian continental paltform.
The mountains are geogically distinct from the rest of the Arabian Peninsula because of the presence of extensive nappes of pleagic sedimentary deposites and ophiolites which overly the shelf carbonate rocks tectonically.
The Oman ophiolite is a remnant of the Tethysian oceanic lithosphere obducted on the Arabian continental margin during the Maastrichtian (around 70 Ma).

 Locating Different Plates
According to the theory of plate tectonics, the Earth's crust and upper mantle are broken into moving plates of "lithosphere." The Earth has two types of crust.
Because the plates are rigid, they tend to stick together, even though they are constantly moving.
When the strength of the rocks at the plate boundary is exceeded, they move rapidly, "catching up" with the rest of the plates.

 Tectonic Plates
Where an oceanic plate collides with a continental plate, the oceanic plate tips down and slides beneath the continental plate forming a deep ocean trench (long, narrow, deep basin.) An example of this type of movement, called subduction, occurs at the boundary between the oceanic Nazca Plate and the continental South American Plate.
Where plates diverge, hot, molten rock rises and cools adding new material to the edges of the oceanic plates.
Plate tectonics, the branch of science that deals with the process by which rigid plates are moved across hot molten material, has helped to explain much in global-scale geology including the formation of mountains, and the distribution of earthquakes and volcanoes.

From a geological standpoint, the Arabian Platform encompasses not only present day Arabia but also the shallow Arabian Gulf (which is not a true ocean basin) and the rocks of the coastal Zagros Mountains of Iran.
Movement of the Afro-Arabian plate during the Palaeozoic twice caused Arabia to pass near the South Pole (in the Ordovician and Carboniferous), and the UAE may have become glaciated.
Earth movements driven by plate tectonics caused the ocean floor of the deep ocean then lying to the north-east to be forced over the edge of the Arabian Platform and its cover of shallow water sediments.

 Geomorphology: Chapter 6 Plate C-9
The Makran coast is on a converging tectonic plate margin, where oceanic lithosphere of the Arabian plate is subducting under the continental Eurasian plate.
Seaward of the Pakistan portion of the Makran shown in this image, the Arabian Plate is subducting northward at a very shallow angle of about 2°, and is dragging Tertiary marine sediments many kilometers in thickness into an accretionary prism at the southern edge of the continent (White and Louden, 1983; Platt et al.
The young sedimentary rocks are being scraped off the downgoing lithosphere and crumpled against the continental margin to form the wide belt of fold mountains that dominates the image.

Major tectonic elements such as the Arabian shield, Central Arabian arch, basalt extrusives (harrats), the Bahrain anticline, Qatar arch, Ghawar anticline, and Central Arabian graben system are clearly expressed on the SIR-C radar images, some of which also reveal structures and geologic features not previously recognized, for example, the Wadi Sabah fault.
Arguably, the most spectacular geology in the world is found in Oman, on the SE corner of the Arabian plate, where ophiolites (oceanic crustal rocks which are derived from depths corresponding to the Mohorovicic discontinuity and upper mantle) have been obducted (shoved, ramped) up onto the Arabian plate.
Subtle evidence of this compression on the periphery of the Arabian plate is represented by warping, erosion, and unconformities in the interior of the Arabian plate.
