Experimental study on the detection of metal sulfide under seafloor environment using time domain induced polarization
The induced polarization (IP) method can play an important role in the exploration of seafloor polymetallic sulfide deposits. Compared to frequency-domain IP, time-domain IP (TDIP) requires a simpler apparatus...

Open AccessMultifractal characterization of the Coniacian–Santonian OAE3 in lacustrine and marine deposits based on spectral gamma ray logs
Limited to the Atlantic and its surrounding basins, the expression of the Coniacian–Santonian oceanic anoxic event (OAE3) was discovered in the non-marine Cretaceous Songliao Basin, Eastern Asia not long ago. ...
