由石英和随机取向的磁性颗粒的混合物组成的湿合成沉积物在几十小时内获得沿外加弱磁场定向的剩余磁化作用。这些结果表明，沉积后颗粒的身体旋转假说是一种物理上可信的机制，通过该假说，含有碎屑铁矿物颗粒的沉积物可以获得沿地磁场精确对准的剩余磁化。
Wet synthetic sediments consisting of mixtures of quartz and randomly oriented magnetic grains acquire, in the course of a few tens of hours, a remanent magenetism directed along an applied weal magnetic field. These results show that the hypothesis of post-depositonal bodily rotation of grains, which has been previously invoked to explain the observed natural remanent magnetization of certain slump, beds, is a physically plausible mechanism by which a sediment containing detrital iron mineral particles can acquire a remanent magnetization accurately aligned along the geomagnetic field.
