Stratigraphic correlation potential of magnetic susceptibility and gamma-ray spectrometric variations in calciturbiditic facies (Silurian-Devonian boundary, Prague Synclinorium, Czech Republic)
2010
Abstract
Magnetic susceptibility (MS) and gamma-ray spectrometry (GRS) stratigraphy were used for correlation and characterization of eight Silurian-Devonian (S-D) sections in the Prague Synclinorium (Czech Republic). They represent two different facies developments: lower subtidal to upper slope deposits and slope-to-basin-floor distal calciturbidites.
The MS and GRS fluctuations between the sections are indicative of a patchy paleoenvironmental mosaic of non-sedimentation, erosion and various sediment accumulation conditions on the sea floor, including also disturbances by syndepositional growth faults and biogenic patchiness effects on the quantity and composition of the source materials.
