The compilation of Sea Beam data from R/VSonne cruises SO43 and SO52, and R/VCharcot cruises Rodriguez 1 and 2 provides an almost continuous bathymetric coverage of a 450-km-long section of the ridge axis. National dishes include sausages with kreolinės, rougaille sauce, octopus with curry, kono-kono (a shellfish) salad and Rodrigues cake. Res. Geophys. North of 22°S, two discontinuities have map geometries that have not been observed previously on slow-spreading ridges. 344, 427–431. Res. However, even in its original state, Rodrigues had some karst, while Mauritius even after suffering 500 years of deforestation can by no means be called "desert" even in a colloquial sense.[6].

Farming was not successful, but there was an abundance of tortoises, turtles, birds, fish and other seafood. Rodrigues is an island that needs to be discovered on foot, whether it is an inland trip or a trip along the edge of the lagoon. Geophys. 9, 73–86. volume 17, pages431–467(1995)Cite this article. The island used to be the tenth District of Mauritius; it gained autonomous status on 10 December 2002, and it is governed by the Rodrigues Regional Assembly. Wessel, P. and Smith, W. H.

A., 1985, Tectonics of Short-Offset, Slow-Slipping Transform Zones in the FAMOUS Area, Mid-Atlantic Ridge,Mar. Res. The ridge is associated with a belt of earthquake epicentres and, hence, is seismically active. During the 18th century several attempts were made by the French to develop the island. - PubMed Google Scholar, Briais, A. 253, 986–994. 3, 295–315. [1] Volcanic rocks from the Rodrigues Island are, however, similar to 1,58-1,30 Ma-old rocks from Réunion and Mauritius and the Rodrigues Ridge can't therefore have originated on the CIR leaving the Réunion hotspot the most likely candidate. Res. Eng. There is also a public swimming pool at Marechal, a village located in the center of the island, and a stadium at Camp Du Rois in the region of Port Mathurin. For statistical purposes, the zones are further subdivided into a total of 182 localities. 72, 441. This diffuse boundary was probably initiated in the Late Miocene and is probably related to opening of Gulf of Aden and the uplift of the Himalayas. [2][1], The only above-water structure near the CIR is the Rodrigues Island, the top of the enigmatic Rodrigues Ridge between Mauritius and the CIR. From the 10th century, Arabs have been known to visit the Mascarene Islands. 15, 153–200. 98, 1793–1812. Res. Part of Springer Nature. Res. The northern section of the CIR, including the Carlsberg Ridge, trends NNW and lacks fracture zones. Plüger, W. L., Herzig, P. M., Becker, K. P., Deissmann, G., Schöps, D., Lange, J., Jenisch, A., Ladage, S., Richnow, H. H., Schulze, T. and Michaelis, W., 1990, Discovery of Hydrothermal Fields at the Central Indian Ridge,Marine Mining Between 21°S and the Marie Celeste Fracture Zone (18°S) the CIR deviates westward. The Rodrigues Ridge is an E-W volcanic structure which extends at 19° S from the Mascarene Plateau (59° 30'E) to 100 km East of Rodrigues Island (64° 30'E). Rodrigues is the only Mascarene island with extensive limestone deposits and caves. The bathymetric data are combined with a GLORIA side-scan sonar swath to visualize the fabric of the ridge and complement the coverage in some areas. [4] Most of the inhabitants are of mixed African and European descent. A 12th-century map by the Arab geographer Ash-Sharif al-Idrisi[verification needed][citation needed] supposedly contains them, and the Cantino planisphere of c. 1500 and some other contemporary maps clearly show the three islands of the Mascarenes as Dina Arobi (or Harobi), Dina Margabin and Dina Moraze.

N., 1988a, A New View of the Mid-Ocean Ridge from the Behaviour of Its Discontinuities,Nature The orthography has been less stable at first, with the name being transcribed Diogo Rodríguez (Spanish maps), Diego Roiz, Diego Ruys (Dutch maps) (or even Diego Ruy's Island), Dygarroys or Bygarroys. Res. 15, 993–997. There are local competitions almost throughout the year and in specific competitions, the winning team travels to Mauritius for sport exchange. The music has an accentuated beat, usually accompanied by an accordion, clapping and the use of improvised percussion instruments like bamboo. Variations in crustal thickness could be related to a broad bathymetric anomaly centered at 19°S, 65°E, which probably reflects the effect of the nearby Réunion hotspot, or an anomaly in the composition of the mantle beneath the ridge near 19°S. Grindlay, N. R., Fox, P. J. and Macdonald, K. C., 1991, Second-Order Ridge Axis Discontinuities in the South Atlantic: Morphology, Structure and Evolution,Mar. Geophys. Reunion hotspot is often viewed as a typical intraplate hotspot, which can be traced back along the southern Mascarene Plateau and the Chagos - Laccadive Ridge to the Deccan flood basalt, caused by the inception of a mantle plume head by the Indian lithosphere. 26, 721–736. The island was home to a now extinct endemic species of flightless bird, the Rodrigues solitaire (Pezophaps solitaria). Small, C., 1994, A Global Analysis of Mid-Ocean Ridge Axial Topography,Geophys. Central Indian Ridge and Reunion Hotspot in Rodrigues Area : Another Type of Ridge - Hotspot Interaction ? 8120 Dynamics of lithosphere and mantle: general. Between the Gulf of Aden and Rodrigues Island, the Mid-Indian Ridge bears the name Carlsberg Ridge. [15], The isolation and location of the island give a microclimate specific to Rodrigues, with two seasons. [7], In 1809, after a brief battle with the French, British troops took possession of Rodrigues.[8]. Rodrigues Ridge connects the Reunion hotspot track with the Central Indian Ridge (CIR) and has been suggested to represent the surface expression of a sub-lithospheric flow channel. The ridge axis deepens and the relief across the axial valley increases from north to south. Fisher, R. L., Sclater, J. G. and McKenzie, D.
