  • Analysis of Plate Spin Motion and Its Implications for Strength of Plate Boundary Takeshi Matsuyama1 and Hikaru Iwamori1,2*
    Matsuyama and Iwamori Earth Planet Sp (2016) 68:36 DOI 10.1186/s40623-016-0405-5 LETTER Open Access Analysis of plate spin motion and its implications for strength of plate boundary Takeshi Matsuyama1 and Hikaru Iwamori1,2* Abstract In this study, we investigate the driving forces of plate motion, especially those of plate spin motion, that are related to the toroidal components of the global plate velocity field. In previous works, numerical simulations of mantle convection have been used to examine the extent to which toroidal velocity components are naturally generated on the surface, by varying key parameters, notably the rheological properties of plates and plate boundaries. Here, we take the reverse approach and perform analyses of observed plate motions, which show an increase in the toroidal/ poloidal ratio at high degrees of spherical harmonic expansion, as well as a rapid change in the plate spin rate and the estimated driving stress around a critical plate size of approximately 1000 km. This quantitative relationship constrains the strength at plate boundaries to 3–75 MPa, which is consistent with several seismological observations, including those from the NE Japan arc associated with the 2011 Tohoku earthquake. Keywords: Plate spin motion, Toroidal–poloidal component, Driving force, Plate boundary, Strength Background simulations of mantle convection that naturally repro- A unique feature of the Earth is active plate tectonics duce the surface motions of plate tectonics (e.g., Richards (Schubert et al. 2001), involving rigid plates that inter- et al. 2001; Tackley 2000a, b).

Geological Evolution of the Red Sea: Historical Background, Review, and Synthesis William Bosworth Abstract The Red Sea is part of an extensive rift system that includes from south to north the oceanic Sheba Ridge, the Gulf of Aden, the Afar region, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Cairo basalt province. Historical interest in this area has stemmed from many causes with diverse objectives, but it is best known as a potential model for how continental lithosphere first ruptures and then evolves to oceanic spreading, a key segment of the Wilson cycle and plate tectonics.

  • The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands
    The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands David Coblentz Earth and Environmental Sciences Division, Los Alamos National Laboratory, Los Alamos, NM Abstract—While the unique geographic location of the Sky Islands is well recognized as a primary factor for the elevated biodiversity of the region, its unique tectonic history is often overlooked. The mixing of tectonic environments is an important supplement to the mixing of flora and faunal regimes in contributing to the biodiversity of the Madrean Archipelago. The Sky Islands region is located near the actively deforming plate margin of the Western United States that has seen active and diverse tectonics spanning more than 300 million years, many aspects of which are preserved in the present-day geology. This tectonic history has played a fundamental role in the development and nature of the topography, bedrock geology, and soil distribution through the region that in turn are important factors for understanding the biodiversity. Consideration of the geologic and tectonic history of the Sky Islands also provides important insights into the “deep time” factors contributing to present-day biodiversity that fall outside the normal realm of human perception. in the North American Cordillera between the Sierra Madre Introduction Occidental and the Colorado Plateau – Southern Rocky The “Sky Island” region of the Madrean Archipelago (lo- Mountains (figure 1).

  • Oil Rights in the Gulf of Suez Richard A
    Louisiana Law Review Volume 38 | Number 4 Summer 1978 Oil Rights in the Gulf of Suez Richard A. Curry Repository Citation Richard A. Curry, Oil Rights in the Gulf of Suez, 38 La. L. Rev. (1978) Available at: https://digitalcommons.law.lsu.edu/lalrev/vol38/iss4/4 This Comment is brought to you for free and open access by the Law Reviews and Journals at LSU Law Digital Commons. It has been accepted for inclusion in Louisiana Law Review by an authorized editor of LSU Law Digital Commons. For more information, please contact [email protected]. OIL RIGHTS IN THE GULF OF SUEZ International law recognizes that coastal nations have the right to exploit natural resources found in continental shelf areas beneath adja- cent water bodies. In most situations the coastal nation entitled to this right is easily identified as the sovereign in actual control of the land immediately adjacent to the water body. However, the nation in physi- cal control of such land may not be the sovereign thereof. In such a case, both the nation having actual control and the nation claiming sov- ereignty may assert the right to exploit natural resources in the adjacent continental shelf. Such a situation currently exists in the Gulf of Suez. When Israel invaded the Sinai in 1967 it acquired the possession but not the sovereignty of that territory. Now, both Egypt, as sovereign, and Israel, as occupant, claim the right to drill for oil in the adjacent conti- nental shelf. The Gulf of Suez is a semi-enclosed body of water which opens into the Red Sea at the south and narrows into the Suez Canal at the north.
