摘要：

Clay mineral content, composition, and solution conductivity are found to affect the postdepositional remanent magnetization (pDRM) strongly. With increasing clay concentration or electrolyte concentration, pDRM intensity decreases. Clay minerals may also be responsible for the inclination shallowing of pDRM. Different clay minerals behave differently. Colloid coagulation is seen as the key to explaining the results. -after Authors
