To assess if the heat-treated <italic>E</italic>1′ centre in quartz is suitable for fluvial sediment provenance tracing, eight granitic samples from sediments and their source rocks with distinct geological ages and origins were collected for electron spin resonance (ESR) measurements.

The heat-treated <italic>E</italic>1′ signal intensity of quartz in sediment samples also shows significant correspondence to those of their source rocks as well as their formation age.
