Airborne geophysical survey: Shiprock 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.

本数据集包含沿飞行航线采集的航空磁测与航空放射性测量数据，由机载仪器同步记录磁场强度、放射性参数及观测点位坐标。其中航空磁测数据集涵盖纬度、经度、高程、磁场强度值，同时包含地质符号或编码，该地质符号源自表层地质图。航空放射性测量数据集则涵盖纬度、经度、高程、地质符号或编码、视铀含量（以铋214等效表征）、钍含量（以铊208等效表征）、钾含量（钾40）、元素比值及辅助信息。
