Lithology refers to the principal geological formation exposed at the surface in the sampling site (see Figure 3 for geological formation descriptions). Source refers to the principal rock type or parent material occurring in the sampling site. LOI = loss-on-ignition (reported in wt.%); bdl = below detection limit.
