Increasing temperature causes fading of fission tracks (FTs) in minerals, which has been quantified by many laboratory heating experiments in atmosphere. In order to elucidate whether or not FT annealing at hydrothermally ...
Carbon isotopic analyses of 24-ethylcholest-5-en-3β-ol in a marine sediment core (KH-79-3, C-3) covering the last 30,000 years, using gas chromatography/isotope ratio mass spectrometry (GC/IRMS), are presented. The source ...
