University of Texas Institute for Geophysics Technical Reports
The University of Texas Institute for Geophysics (UTIG) research staff present their research findings/results/ scientific summaries as peer-reviewed publications in various journals or at scientific meetings which often have distribution limitations. Research summaries/results may also be presented as technical reports and made public. Some of these are made available here.

Depth and Age in the South Atlantic (Paleoceanographic Mapping Project Progress Report No. 40-0888)
(Institute for Geophysics, 1988)A significant flattening of the relation between depths and age of ocean floor older than 80 Ma can be explained by assuming that the oceanic lithosphere acts as a thermal boundary layer on top of a viscous upper mantle. ... -
Opening of the Central North Atlantic: Revised Seafloor Spreading Isochrons and Tectonic Map from Geosat Data (Paleoceanographic Mapping Project Progress Report No. 39-0888)
(Institute for Geophysics, 1988)Plate reconstructions for the opening of the Central and North Atlantic were made by combining Geosat altimetry and magnetic anomaly data. Geosat deflection of the vertical (horizontal gravity) data, which reflect the short ... -

Plate Tectonic Reconstructions of the Cretaceous and Cenozoic Ocean Basins (Paleoceanographic Mapping Project Progress Report No. 34-1287)
(Institute for Geophysics, 1987)In this paper we present nine reconstructions for the Mesozoic and Cenozoic, based on the sea-floor spreading isochrons published by Larson et al. (1985). The purpose of this study was: 1) to determine if the isochrons ... -

Tectonic Fabric Map of the Ocean Basins from Satellite Altimetry Data (Paleoceanographic Mapping Project Progress Report No. 32-1287)
(Institute for Geophysics, 1987)Satellite altimetry data provides a new source of information on the bathymetry of the ocean floor. This study used the SEAS AT and GEOSA T altimetry data to produce a global map which displays the tectonic fabric of the ... -
Evolution of the Antarctic Continental Margins (Paleoceanographic Mapping Project Progress Report No. 31-1287)
(Institute for Geophysics, 1987)With the exception of the Pacific facing margin of West Antarctica between Thurston Island and the tip of the Antarctic Peninsula, all of the continental margins of Antarctica are either rifted passive margins or sheared ... -
Crustal Structure of the South Florida Bank Derived from Ocean Bottom Seismometer Refraction Profiles (Final Report on Refraction Experiments that were part of the South Florida Bank Study)
(Institute for Geophysics, 1984)In March 1982, six seismic refraction lines, 70 to 90 km long, were shot in the southeastern Gulf of Mexico using the advanced Texas digital ocean bottom seismometers. Five lines were on the South Florida bank region in ... -
Report to Landmark Graphics Corporation, University Partnership Program
(Institute for Geophysics, 1989)Seismic processing requires accurate knowledge of the earth's velocity structure to properly image and interpret multi-fold seismic data. Conventional analysis methods are based on determining the best fit hyperbolas to ... -
Computer Programs to Translate LIS Format, Verical Seismic Profile (VSP) Data to SEG-Y Exchange Data Tape Format
(Institute for Geophysics, 1988-12-23) -
Southeast Asia (Paleoceanographic Mapping Project Progress Report No. 44-0888)

Tectonic History and New Isochron Chart of the South Pacific (Paleoceanographic Mapping Project Progress Report No. 43-0888)
(Institute for Geophysics, 1988)We have developed an internally consistent isochron chart and a tectonic history of the South Pacific using a combination of new satellite altimeter data and shipboard magnetic and bathymetric data. Highly accurate, vertical ... -
Preliminary Tectonic Fabric Chart of the Indian Ocean (Paleoceanographic Mapping Project Progress Report No. 42-0888)

Evolution of the Eastern Indian Ocean since the Late Cretaceous Contraints from Geosat Altimetry (Paleoceanographic Mapping Project Progress Report No. 41-0888)
(Institute for Geophysics, 1988)We propose a new model for the tectonic evolution of the Eastern Indian Ocean from the Late Cretaceous to the present. Two types of data are used to improve previously-published reconstructions. First, reinterpreted seafloor ... -
Development of the Circum-Pacific Panthallassic Ocean during the Early Paleozoic (Paleoceanographic Mapping Project Report No. 10-0386}
(Institute for Geophysics, 1986)Though the Pacific plate is less than 200 million years old, the Circum-Pacific ocean basin (Panthallassic ocean basin) has probably been in existence since Precambrian times. During the Early Paleozoic the Tasman ... -
Cenozoic Evolution of the American-Antarctic Ridge (Paleoceanographic Mapping Project Report No. 09-0286)
(Institute for Geophysics, 1986)New bathymetric and magnetic anomaly data for the American-Antarctic Ridge region of the South Atlantic are compiled and presented. The magnetic anomaly data are used to produce poles of rotation and angles of opening for ... -

Paleomagnetic Constraints on the Fit of the Continents Around the Gulf of Mexico (Paleoceanographic Mapping Project Report No. 07-1285)
(Institute for Geophysics, 1985)Paleomagnetic results from the Heldenberg and Trenton carbonates have been shown to be remagnetizations of Late Carboniferous or Early Permian age, and these results differ in a systematic way from other North American ...
