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.

No abstract available.AuthorsS. L. Snyder, J. D. PhillipsStudies related to the Charleston, South Carolina, earthquake of 1886 — Tectonics and seismicity
Since 1973, the U.S. Geological Survey (USGS), with support from the Nuclear Regulatory Commission, has conducted extensive investigations of the tectonic and seismic history of the Charleston, S.C., earthquake zone and surrounding areas. The goal of these investigations has been to discover the cause of the large intraplate Charleston earthquake of 1886, which dominates the record of seismicity iAuthorsDavid Gottfried, C. S.

A study was made of the relationship between lineaments observed on Landsat satellite images and the geologic framework of a portion of the Allegheny Plateau of south-central New York and northern Pennsylvania. The area is underlain by a relatively thick sequence of salt and other evaporites in the Silurian Salina Group and is a potential site for deep-storage of solid nuclear waste. A combinationAuthorsM. H. Podwysocki, H. A. Pohn, J. D. Phillips, M. D. Krohn, T. L. Purdy, I.S. MerinADEPT: a program to estimate depth to magnetic basement from sampled magnetic profiles
A fortran program computes depth to magnetic basement from the spatially varying autocorrelation function of a sampled magnetic profile. The depth calculation assumes a particular form for the autocorrelation function, and this assumption is tested against the measured autocorrelation function in order to reject invalid depth estimates.AuthorsJeffrey D.
