Experimental work by the writers suggests that electrical currents and potentials affect some diagenetic processes; this may be termed "electrodiagenesis." It was discovered that currents (produced chiefly by ionic exchange processes) flowing through sediments may stimulate cementation and the formation of authigenic minerals such as gibbsite, limonite, calcite, hydrohematite, hydrogoethite (lepidocrocite), hisingerite, allophane, allophanoid, gypsum, hematite, magnetite, nontronite, trona, and natron (Na 2 CO 3 .10H 2 0). Currents may also cause selective ion drive and explain zonation of some trace elements, various minerals, etc.
