Richard G. Gordon (born 1953) is an American geophysicist, known for his research on global tectonics, including global plate motions and palaeomagnetism. He is noteworthy for leading two global plate motion projects: NUVEL (Northwest University Velocity) and MORVEL (Mid-Ocean Ridge Velocity). [1] [2] [3] [4] [5] In the geosciences, NUVEL and MORVEL are standard models for global plate motions. [1]

Education and career

Richard G. Gordon was born in California and grew up in east San Jose in the Diablo Range foothills. [6] He graduated in 1975 from the University of California, Santa Cruz with a B.A. in geophysics. At Stanford University he graduated in geophysics with an M.S. in 1975 with a Ph.D. in 1979. [7] His Ph.D. thesis was supervised by Allan V. Cox. For the academic year 1978–1979 Seth Stein was a postdoc at Stanford University. Stein and Gordon began a collaboration on global plate motions — their collaboration lasted over a number of years. In 1979 Stein joined the faculty of geological sciences of Northwestern University. After a postdoctoral year of teaching and research at Stanford, Gordon also joined Northwestern University faculty of geological sciences. He spent 15 years on Northwestern's faculty. [6] Two of Gordon's former doctoral students Charles "Chuck" DeMets (Ph.D. 1988) [8] and Donald Argus (Ph.D. 1990) [9] at Northwestern University were eventually elected Fellows of the American Geophysical Union (AGU) [1] (DeMets in 2011 [8] and Argus in 2018 [9] ). Gordon, Stein, DeMets, and Argus collaborated extensively. [10] [11] [12] In 1995 Gordon joined the faculty of Rice University, [6] where he is currently W. M. Keck Foundation Professor in Geophysics, Earth, Environmental and Planetary Sciences. [13] In 2020 he gave a lecture at Beijing's China University of Geosciences (CUG). [14]

Gordon's research on global tectonics, tectonophysics, and paleomagnetism has earned him an international reputation. [1] In 1984 Gordon coauthored, with Allan V. Scott and Scott O'Hare, an important paper on palaeomagnetic Euler poles. [15] [1] Gordon's research in tectonophysics has made use of marine geophysics, space geodesy, geodynamics, and numerical modeling. [6] [13] The research of Gordon and his colleagues have quantified relative motions within major tectonic plates and thereby identified at least three major problems with the original theory of plate tectonics. First, the global plate interiors are less rigid than originally hypothesized. Second, the earliest models of plate tectonics need the incorporation of diffuse boundaries among oceanic plates. Third, global plate reconstructions sometimes need the incorporation of effects of horizontal thermal contractions found in geologically young oceanic lithosphere — such thermal contractions are relevant to understanding relative motions among hot spots. [1]

Gordon was awarded an Alfred P. Sloan Foundation Research Fellowship for the academic year 1984–1985. [13] In 1989 he was elected a Fellow of the American Geophysical Union (AGU) [16] and also received the AGU's James B. Macelwane Medal. In 1998 he gave the AGU's Birch Lecture. In 2002 he received the Arthur L. Day Medal from the Geological Society of America (GSA). [13] Upon the occasion of Dan McKenzie's winning of the 2002 Crafoord Prize in Geosciences, Gordon was honored as one of six Earth science Lecturers in the 20002 Crafoord Prize Symposium. [17] In 2019 Gordon was elected a Fellow of the American Association for the Advancement of Science. [18] [19] In 2023 he was awarded the Stephan Mueller Medal of the European Geosciences Union (EGU). [1]

<span class="mw-page-title-main">Plate tectonics</span> Movement of Earths lithosphere

Plate tectonics is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. Plate tectonics came to be accepted by geoscientists after seafloor spreading was validated in the mid-to-late 1960s.

<span class="mw-page-title-main">Mid-ocean ridge</span> Basaltic underwater mountain system formed by plate tectonic spreading

A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. The rate of seafloor spreading determines the morphology of the crest of the mid-ocean ridge and its width in an ocean basin.

Allan Verne Cox was an American geophysicist. His work on dating geomagnetic reversals, with Richard Doell and Brent Dalrymple, made a major contribution to the theory of plate tectonics. Allan Cox won numerous awards, including the prestigious Vetlesen Prize, and was the president of the American Geophysical Union. He was the author of over a hundred scientific papers, and the author or editor of two books on plate tectonics. On January 27, 1987, Cox died in an apparent suicide.

The Rodrigues Triple Junction (RTJ), also known as the Central Indian [Ocean] Triple Junction (CITJ) is a geologic triple junction in the southern Indian Ocean where three tectonic plates meet: the African Plate, the Indo-Australian Plate, and the Antarctic Plate. The triple junction is named for the island of Rodrigues which lies 1,000 km (620 mi) north-west of it.

The Nankai Trough is a submarine trough located south of the Nankaidō region of Japan's island of Honshu, extending approximately 900 km (559 mi) offshore. The underlying fault, the Nankai megathrust, is the source of the devastating Nankai megathrust earthquakes, while the trough itself is potentially a major source of hydrocarbon fuel, in the form of methane clathrate.

<span class="mw-page-title-main">Balmoral Reef Plate</span> Small tectonic plate in the south Pacific north of Fiji

The Balmoral Reef Plate is a small tectonic plate (microplate) located in the south Pacific north of Fiji. Clockwise from the north, it borders the Pacific Plate, the Australian Plate, Conway Reef Plate, and the New Hebrides Plate. The northern and western borders are a divergent boundary while the rest of the borders are transform and convergent boundaries. The Balmoral Reef Plate's ocean crust is less than 12 million years old and is spreading between the New Hebrides and Tonga subduction. The plate forms the west central part of the seafloor of the North Fiji Basin.

<span class="mw-page-title-main">Conway Reef Plate</span> Small tectonic plate in the south Pacific west of Fiji

The Conway Reef Plate is a small tectonic plate (microplate) located in the south Pacific west of Fiji. The western boundary is with the New Hebrides Plate while the eastern is with the Australian Plate. A short transform boundary also exists with the Balmoral Reef Plate. Much of the plate underlies the south central portion of the North Fiji Basin.

Plate reconstruction is the process of reconstructing the positions of tectonic plates relative to each other or to other reference frames, such as the Earth's magnetic field or groups of hotspots, in the geological past. This helps determine the shape and make-up of ancient supercontinents and provides a basis for paleogeographic reconstructions.

The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses. The continental drift/ Airy-Heiskanen isostasy hypothesis had many flaws and scarce data. The fixist/ Pratt-Hayford isostasy, the contracting Earth and the expanding Earth concepts had many flaws as well.

The Lwandle Plate is one of three tectonic microplates, along with the Rovuma Plate and Victoria Plate, that make up the African Plate with the Somali Plate and the Nubian Plate. Its discovery is very recent, so the velocity of the plate is neither well known nor well understood. Many experiments are ongoing to quantify this. The Lwandle Plate lies between 30°E and 50°E, sharing a boundary with the Nubian, Somali, and Antarctic Plates.

Oblique subduction is a form of subduction for which the convergence direction differs from 90° to the plate boundary. Most convergent boundaries involve oblique subduction, particularly in the Ring of Fire including the Ryukyu, Aleutian, Central America and Chile subduction zones. In general, the obliquity angle is between 15° and 30°. Subduction zones with high obliquity angles include Sunda trench and Ryukyu arc.
