Abstract

Natural gamma-ray spectrometry on coastal sections from Redcar and Robin Hood's Bay permits the radioactive characterization of five different mudstone units and the construction of an outcrop gamma-ray log for the Lower Lias. Correlation of these five units with their equivalents in the gamma-ray log of the Felixkirk Borehole, located 40 km to the west, has been established. A spline curve fitted through the total radioactivity data emphasizes low frequency cyclicity in the outcrop section. These cycles appear to be correlatable with cycles of comparable wavelengths in the low-pass filtered gamma-ray log of the Felixkirk Borehole. Sedimentological evidence confirmed high radioactivity peaks correspond to transgressive phases. -from Authors
