Magnetic susceptibility was measured on outcropping rock in the eastern Adirondack Mountains, New York. A Terraplus KT-20 was used for the measurements. The corresponding rock type was identified using standard field geologic approaches. Locations of the outcrops were determined using a handheld GPS.

Radiometric (gamma spectrometry) measurements were made on outcropping rock and during walking surveys in the eastern Adirondack Highlands, New York using a GF Instruments Gamma Surveyor. Outcrop measurements were made over 2-minute intervals directly on rock. Walking surveys involved recording measurement averages over 30-second intervals while holding the instrument approximately 1 meter above the ground. Locations were obtained via a handheld GPS. For the outcrop measurements, rock types were identified using standard field methods. Walking surveys were conducted near magnetite-apatite deposits and in areas with mine tailings. For more information on radiometric methods, please see the International Atomic Energy...

Petrophysical data were collected in the eastern Adirondack Highlands during several field campaigns in 2016-2017. This data release provides magnetic susceptibility, gamma spectrometry, and density measurements on rock outcrops, hand samples, and during walking surveys. Rock types for the outcrops and samples were identified using standard field methods. Locations of the outcrops or samples were determined using a handheld GPS.

The density of rock samples collected 2016-2017 from the eastern Adirondack Highlands in New York was measured in the laboratory using standard immersion methods. The corresponding rock type was identified using standard field geologic approaches. Rock locations were determined in the field using a handheld GPS.
