Purpose: Aeromagnetic data were collected within the region to identify magnetic features as a basis for geophysical interpretations. Supplemental_Information: High resolution aeromagnetic data were collected by EON Geosciences, Inc. using Geometrics G-822A cesium magnetometer for the airborne measurements and GEM System Overhauser GSM-19 magnetometer for the ground measurements. Lines were flown in a northeast-southwest direction and were spaced 800m apart. Northwest-southeast tie lines were also flown spaced 8000 m apart. The survey was flown at a nominal 305m above topography.

Although the digital form of the data stores location and attribute values to several decimals of precision, the data is subject to the accuracy and precision inherent in the data due to data collection and processing limitations. Where this data is used in combination with other data, the precision and accuracy of the resulting dataset is limited by the precision and accuracy of the input datasets. Acknowledgement of the U.S. Geological Survey is appreciated for products derived from these data.
