Method for determination of clay and mica consentrations in underground sandstone formations by radioactivity logging

An underground formation is logged for the registration of natural gamma radiation from trace amounts of thorium, uranium and potassium. Both the clay and mica content for an interesting interval is determined from natural gamma activities in the interval of interest, in a pure sandstone interval and in a shale interval free from mica
