Preferred Citation: Francis Raymond Boyd Papers, 1912-2003, Geophysical Laboratory, Carnegie Institution of Washington, Washington, D.C. Processing: This collection was processed by Ann Mulfort, Library/Archives Intern, in September 2004, through the generous support of the National Historical Publications and Records Commission. F. R. Boyd Biographical Sketch Francis Raymond Boyd, Jr., known as “Joe” Boyd, was born in Boston, Massachusetts on January 30, 1926. He received an AB degree in 1949, an MS degree in 1951, and a PhD degree in 1958 all in geology from Harvard. He also received an MS degree in geology from Stanford in 1950. His Ph. D. work was entitled: “Geology of the Yellowstone Rhyolite Plateau,” and his research was featured in the 1998 IMAX film, “Yellowstone.” Boyd began work for the Geophysical Laboratory (GL) of the Carnegie Institution of Washington (CIW) in 1953, and conducted geological research throughout his entire career there. He continued researching and contributing to the scientific world of geology even after his retirement in 1996, until just before his death on January 12, 2004. Boyd’s contributions to the field of high-pressure experimental studies and petrologic investigations are many. His first major achievement was the development of a piston-cylinder apparatus in the early 1960s. In collaboration with GL machinist, Joe England, the Boyd- England device has been used by hundreds of scientists around the world to create synthetic diamonds by simulating high pressure on minerals in the earth’s mantle. The apparatus allowed Boyd to conduct studies on pyroxene-garnet phase relations, and created a career long interest in studying mantle xenoliths. This interest led him to his involvement in the studies of kimberlites found in Lesotho, Africa being collected by Peter Nixon in the early 1970s. Francis Raymond Boyd Papers, 1912-2003 Page 1 The First International Kimberlite Conference (IKC) was held in Cape Town, South Africa in 1973. The work presented at this conference, in collaboration with Nixon, paved the way for Boyd’s continued involvement in the seven subsequent conferences held worldwide through 2003. His expertise in this field was widely recognized and he remained an active member of the Advisory Committee for the conferences. Because of his wide-ranging studies in this area, his interest in the mantle root of the Kaapvaal craton in southern Africa also developed. He traveled extensively for his investigations, and collaborated with scientists from around the world. His major collaboration included work with petrologists and geochemists at the Institute of Mineralogy and Petrology at Novosibirsk, Russia, and the Department of Earth Sciences at the University of Leeds, UK. This work, presented at the fifth IKC in 1991 with Nixon; Graham Pearson, Louis Brown, Steve Shirey and Richard W. Carlson of the Department of Terrestrial Magnetism at CIW; and N. P. Pokhilenko, focused on similarities and differences between lithospheres forming the Siberian Platform and the Kaapvaal craton. Boyd authored or co- authored over 75 research papers, and was generous in his sharing of information with fellow scientists. In 1974, he was elected to the National Academy of Sciences, and in 1982, he received a medal of honor from the town officials while at the third IKC in Clermont-Ferrand, France. He was a fellow in the Mineral Society of America, the Geological Society of America, the American Geophysical Union, and served as both the secretary and president of the Geochemical Society. He was called upon by many institutions to lecture on the numerous subjects within his expertise for which he became widely known. In his later career, he collaborated with fellow CIW staff member, Yingwei Fei, to create a cubic-anvil apparatus. This device allows scientists to conduct phase studies providing data that aid in the understanding of the processes of the earth’s formation. Dr. Boyd will be remembered as one of the great contributors to the understanding of the evolution of the earth’s upper mantle. Scope and Contents Note The collection includes correspondence, photographs, apparatus design drawings, meeting and lecture notes, and laboratory notebooks that document the work of Francis Raymond Boyd, Jr. throughout his career at CIW, which spanned over 40 years. His research involved high-pressure experimental studies and petrologic investigations of mantle rocks, including kimberlites. The materials are housed in five records center cartons and two document boxes. There are also oversized materials contained in two map case drawers. Arrangement The collection is arranged in four series. Series 1. Correspondence, n.d., 1912-2003 Series 2. Meeting and Lecture Notes, 1969-2003 Series 3. Single Stage Designs, n.d., 1930-1974 Series 4. Laboratory Notebooks, n.d., 1957-1969 Francis Raymond Boyd Papers, 1912-2003 Page 2 Series 1: Correspondence, n.d., 1912-2003 This series contains Boyd’s extensive correspondence. He organized his files by correspondent, and by topic. Maintaining Boyd’s organization of these materials, files previously placed in storage by Boyd were reintegrated into his main files resulting in several folders for a few correspondents. The first set of files is alphabetical by correspondent followed by topical categories. For the researcher’s ease of use, these topical categories are alphabetized and within each category original order was maintained. Boyd’s topical categories, when not included in the folder title, are supplied in brackets preceding the folder title. The materials in this series demonstrate Boyd’s congeniality and willingness to share information within his scientific community. There are also examples of his enthusiasm for making recommendations of colleagues in the profession. Communication between correspondents began on strictly professional bases, but many personal relationships developed which illustrate the respect and admiration that Boyd enjoyed from his colleagues. The last folder in this series contains the correspondence gathered from his desk after his passing. Series 2: Meeting and Lecture Notes, 1969-2003 The materials in this series well document Boyd’s extensive travel, as he conducted geological research and shared his scientific discoveries in meetings and presentations. It concludes with the International Kimberlite Conference materials, which comprised a major portion of Boyd’s professional life. Boyd’s original order of the folders is maintained, and is in roughly chronological order. Series 3: Single Stage Designs, n.d., 1930-1974 This series includes original drawings presumably created by Boyd and his colleagues which document designs for high pressure devises. These drawings were maintained separately from Boyd’s files. The original order of the drawings was preserved. Series 4: Laboratory Notebooks, n.d., 1957-1969 These notebooks detail Boyd’s experimental runs of high-pressure studies on geological samples. There were eight separate notebooks, only one of which bore a title. They are arranged in chronological order by the earliest date within each notebook and numbered accordingly. Due to the size of the notebooks, each notebook spans several folders. Where it was possible to determine discreet experimental runs by the coding and titling found in the data, these notebook sections were placed in separate folders. Otherwise, folder breaks are based on volume of pages. Francis Raymond Boyd Papers, 1912-2003 Page 3 Folder Listing Box Folder Series 1: Correspondence, n.d., 1912-2003 P.H.

The history of the explordtion of the Central Arctic Ocean is reviewed.It has been only within the last 15 years that any signifi- cant number of depth-sounding data have been collected.The present study uses seven million echo soundings collected by U. S. Navy nuclear submarines along nearly 40, 000 km of track to construct, for the first time, a reasonably complete picture of the physiography of the basin of the Arctic Ocean.The use of nuclear submarines as under-ice survey ships is discussed. The physiography of the entire Arctic basin and of each of the major features in the basin are described, illustrated and named. The dominant ocean floor features are three mountain ranges, generally paralleling each other and the 40°E. 140°W. meridian. From the Pacific- side of the Arctic basin toward the Atlantic, they are: The Alpha Cordillera; The Lomonosov Ridge; andThe Nansen Cordillera. The Alpha Cordillera is the widest of the three mountain ranges. It abuts the continental slopes off the Canadian Archipelago and off Asia across more than550of longitude on each slope.Its minimum width of about 300 km is located midway between North America and Asia.In cross section, the Alpha Cordillera is a broad arch rising about two km, above the floor of the basin.The arch is marked by volcanoes and regions of "high fractured plateau, and by scarps500to 1000 meters high.The small number of data from seismology, heat flow, magnetics and gravity studies are reviewed.The Alpha Cordillera is interpreted to be an inactive mid-ocean ridge which has undergone some subsidence.

    INFORMATION TO USERS This material was produced from a microfilm copy of tha original document. Whila the most advanced technological meant to photograph and reproduce this document have been used, tha quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Pegs(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pagas to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find » good image of the pege in the adjacent frame; 3. Whan a map, drawing or chart, etc., was part of the materiel being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at tha upper left hand comer of a large sheet and to continue photoing from left to right iii equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.

  • Seismological Monitoring of the World's First
    Appendix A Seismological Monitoring of the World’s First Nuclear Detonation— The Trinity Shot of 16 July 19451 Seismology played a modest role in the Trinity test, thereby establishing, at the very birth of the “atomic age,” a mutual interaction between seismology and nuclear testing that would become of increasing significance to both technologies as the century pro- gressed. Because the Trinity “gadget” was designed to be an atmospherically detonated military weapon for which principal damage effects were expected to be air blast and accompanying ground shock of intensities heretofore unexplored, extensive new effects data were needed to plan military applications. When the need for a full-scale test of the implosion design became clear by late 1944, Los Alamos scientists began to devise field experiments to measure both air blast and ground shock.Also, they wanted to esti- mate how each would scale with explosive energy release (yield), range, and height of burst within a principal target area (nominally, within about 20 km of ground zero). In March 1945, Herbert M. Houghton, an exploration geophysicist with Geophys- ical Research Corporation (GRC) and Tidewater Oil, was recruited to work with Los Alamos physicist, James Coon, to perfect earth shock instrumentation for the 100-ton TNT calibration rehearsal shot of 7 May 1945, as well as the unique multikiloton Trin- ity nuclear event planned for July. Houghton and Coon modified a dozen GRC Type SG-3 geophones to record both vertical and horizontal-radial components of strong ground motion at ranges between 0.75 and 8.2 km from both the calibration and nuclear shots, which were air bursts suspended on towers.

Virginia 22092 Inferring principal stress directions from geologic data, focal mechanisms, and in situ stress measure­ ments, we have prepared a map of principal horizontal stress orientations for the conterminous United States. Stress provinces with linear dimensions which range between 100 and 2000 km were defined on the basis of the directions and relative magnitude of principal stresses. Within a given province, stress orientations appear quite uniform (usually within the estimated range of accuracy of the different meth­ ods used to detennine stress). AvailabJe data on the transition in stress direction between the different stress provinces indicate that these transitions can be abrupt, occurring over <75 km in places.
