This rock can be weathered and eroded, then redeposited and lithified into a sedimentary rock. Slab avalanches form frequently in snow that has been deposited, or redeposited by wind. The redeposited cementing material is most commonly calcareous or siliceous. The lahar deposits sometimes have been reworked and redeposited by small streams. An even larger problem is the tritium co-deposited with the redeposited graphite. The redeposited Sn might be subsequently removed by atomic hydrogen exposure. Treated soil may be redeposited onsite, used as cover in landfills, or incorporated into asphalt. The majority of Chalk reservoirs are redeposited allochthonous beds. The amber does not appear to have undergone significant transport since hardening or be redeposited. Instead, it redeposited the funds to designated banks at interest. Huge dust clouds were moved and redeposited over broad areas.
