Extract

Interfacial methods are a group of newly emerging techniques for recovering phosphatic microfossils from disaggregated sediment residues by exploiting the lipophilic surface properties of apatite (Freeman, 1982). When a sediment residue is placed in a two-phase mixture of water and a water-insoluble organic liquid, the organic liquid wets the phosphate particles in preference to the gangue minerals, most species of which are wetted by the water instead.
