WebWeddellite can be found as authogenic crystals in sea floor mud. It also has been reported in peat bearing sediments and in calcite bearing lacustrine sediments. It occurs with whewellite, urea, phosphammite, and aphthitalite. Together, whewellite and weddellite are the most common renal calculi (kidney stones).
