Airborne geophysical survey: Corbin 1° x 2° Quadrangle

Aeromagnetic and aeroradiometric data were collected along flight lines by instruments in an aircraft that recorded magnetic-field and radiometric values and locations. The magnetic data set presents latitude, longitude, altitude, and magnetic-field values. Geologic symbols or codes are also included. The geologic symbols were picked from surficial geologic maps. The radiometric data set presents latitude, longitude, altitude, geologic symbols or codes, apparent Uranium (Bismuth 214), Thorium (Thallium 208), and Potassium (K 40), the element ratios, and ancillary information.航空磁测数据（Aeromagnetic data）与航空放射性测量数据（aeroradiometric data）沿飞行测线由机载仪器采集，该类仪器同步记录了磁场值、放射性测量值及点位坐标。 该磁测数据集涵盖纬度、经度、飞行高度及磁场值，同时附带地质符号或编码。 上述地质符号源自地表地质图件。 该放射性测量数据集涵盖纬度、经度、飞行高度、地质符号或编码、视铀（铋214）、钍（铊208）、钾（钾40）、元素比值及辅助信息。
