Relation of an Airborne Magnetic Profile to the Geology Along the Kansas-Nebraska Border

Abstract

An airborne magnetic profile made in 1948 is shown in relation to the stratigraphy and structure along the Kansas-Nebraska state line. Rocks ranging in age from Precambrian to Recent are present, and the magnetic profile crosses several major structural provinces, including the Hugoton embayment, Cambridge arch, Salina basin, Nemaha anticline, and Forest City basin.

Variation in the thickness of post-Precambrian rocks produces regional magnetic values that increase to the east. Near-surface disturbances possibly cause numerous minor magnetic irregularities. In western Kansas, the magnetic data indicate the position and configuration of the Precambrian basement, whereas in eastern Kansas they seemingly reveal the general distribution of the Precambrian rock types.
