This collection (known internally at Maryland Geological Survey as Component 8) consists of 211 infrared, 9 in. by 9 in. aerial photographs (211 unique frames) flown on a 7.5-minute U.S. Geological Survey (USGS) quadrangle basis. The photographs date from 1988-1989 and were flown or otherwise acquired by the USGS National Aerial Photograph Program (NAPP). The Maryland counties covered by these photographs include Allegany, Anne Arundel, Calvert, Cecil, Charles, Dorchester, Kent, Prince George’s, Queen Anne’s, Somerset, St. Mary’s, Talbot, Washington, and Worcester Counties. The scale of these photographs is not printed on the photographs; however, Maryland Geological Survey (MGS) calculates the scale to be approximately...

The current database consists of location 9,032 entries. The surface-based, point data include 5,272, 6,939, and 903 density, magnetic susceptibility, and NRM measurements, respectively. Downhole data from 146 drillcore have also been incorporated, yielding an additional 1,145 and 9,622 measurements of density and magnetic susceptibility, respectively. Geologic interpretation of gravity and magnetic anomaly data in a given area is greatly enhanced if density, magnetic susceptibility (MS) and natural remanent magnetization (NRM) data are available for representative rock-types (Chandler and others, 2008). Along with geologic information from outcrop and drill-holes, rock property data help relate geophysical anomaly...

Kelsey Boltz has been a registered mining engineer and geologist in Arizona since the mid 1960s. A 1953 graduate of the Colorado School of Mines, he founded Colamer Corporation and Nuclear Dynamics, both companies active in the uranium industry in the Grants Uranium Region of New Mexico in the '50s, '60s and '70s. In 1981 he co-founded Century Capital, Inc., an investment banking and retail brokerage firm which provided several hundred million dollars financing for various industries including natural resource companies. In 1990 he started his exploration consulting company, Boltz Group International, which initiated and managed several mining projects in Mexico, Chile and Bolivia. The collection consists of geologic...

This collection primarily contains economic geologic information on mines in Mohave County, but also includes more general files on other states and mineral commodities. William Crutchfield, Jr. earned his master's degree from The University of California in 1953. He began working for Santa Fe Mining, Inc. in California in the 1960s as a Mining Engineer and later as Exploration Manager. He stayed with the company until the 1980s.
