Airborne Magnetic Total-Field Survey, Iron Mountain-Menominee Region, Michigan-Wisconsin, USA This data release includes the airborne magnetic survey data collected from the Iron Mountain-Menominee region of Michigan and Wisconsin. The Mineral Resources Program of the U.S. Geological Survey is tasked with understanding the nation's mineral resources. Precambrian rocks in the region are poorly mapped and understood. Detailed high-resolution airborne magnetic surveys, ground gravity surveys, and limited borehole data are being used to better understand the lithology and structure of both exposed and concealed Precambrian rocks. The primary goal of the airborne magnetic survey is to map lateral variations of magnetization that are related to differences in rock type.

This data set, as well as its documentation, are available in U.S. Geological Survey Open-File Report 2004-1001 (https://mrdata.usgs.gov/geochem/doc/home.htm). The titanium concentrations were measured in 3,457 samples of stream sediments from the coastal plain of the southeastern United States; this area includes parts of Virginia, North Carolina, South Carolina, Georgia, Florida, and Alabama. The samples were collected between 1975 and 1999 during several field surveys, and the concentrations were measured using inductively coupled plasma-atomic emission spectrometry.
