Jeffrey Phillips
Jeff Phillips is a Scientist Emeritus (Geophysics) in the Geology, Geophysics, and Geochemistry Science Center in Denver, Colorado. He develops and maintains the USGS potential-field geophysical software package for the PC, a public-domain resource for the geophysical community.
Jeff's research focuses on potential-field theory and its application to geologic problems, including water, mineral, and energy resources.
Dr. Phillips has conducted geophysical research for over 40 years in support of USGS programs on Energy and Mineral Resources. He is a specialist in the analysis of potential-field (gravity and magnetic) geophysical data. He has published more than 70 professional reports and presented more than 60 talks at scientific meetings. Dr. Phillips has worked extensively on Energy Resource studies in Alaska and recently participated in Central Asia Mineral Resource Assessments. His recent work for other Federal Agencies includes a dam safety study in California and a geophysical investigation at the former Nevada Test Site.

In this review, we discuss publications during the last quadrennium (1987–1990) that used aeromagnetic data, marine magnetic data, satellite magnetic data, and rock magnetic and petrologic data to provide information on the sources of magnetic anomalies. Abstracts and papers by non‐U.S. authors are not described.The publications reviewed reflect increased integration of rock magnetic property andAuthorsJeffrey Phillips, Richard J. Reynolds, Herbert FreyE-4 Central Kentucky to the Carolina Trough
E-4 is one of eight Geodynamics transects that cross the Atlantic margin of North America between Georgia and Newfoundland. Five of the transects are in the United States and three are in Canada. Transect E-4, which is 110 km wide and more than 1,100 km long, extends from the stable North American craton just west of the Grenville front near Lexington, Kentucky southeastward across Cape Fear, NortAuthorsDouglas W.

Two North American contributions to the Global Geoscience Transects Program, the Quebec-Maine-Gulf of Maine transect and the Great Lakes portion of the United States-Canadian Border transect, are among the first to produce digital geology in a form that can be combined with gridded gravity and aeromagnetic data.
