Abstract Studying the trace organic matter (OM) in shale is of great significance to develop exploration plans for shale oil and gas exploration. Due to the low OM content, currently there are significant limitations in determining shale trace OM characteristics. This paper reports the analysis of the pyrolyzation products of shale using THz time-domain spectroscopy (THz-TDS) technology combined with pyrolyzation technology, based on the sensitivity of THz to organic and mineral differences. The THz parameters, including the time delay and amplitude of the THz peaks, were extracted to describe the pyrolyzation of shale. In the first-stage of pyrolyzation, the THz response does not change significantly in the range of
